The invention provides a micro-grid construction data processing method of a bidirectional charging pile, which is shown in fig. 1 and comprises the following steps of S1-S4:
s1, obtaining bidirectional charge and discharge nodes in a micro-grid where the bidirectional charge piles are located, and obtaining an intra-node circuit and an extra-node circuit corresponding to the bidirectional charge and discharge nodes based on the division of the bidirectional charge and discharge nodes on the micro-grid.
The bidirectional charging pile is a charging pile capable of charging and discharging, and the micro-grid is a small power generation and distribution system consisting of a distributed power supply, an energy storage device, an energy conversion device, a load, a monitoring device and the like, and is expected to be a small power grid. For example, the power grid of the home may be a micro-grid, i.e. a power network of the home connected to a mains powered node. The bidirectional charging and discharging node is the node where the bidirectional charging pile is located in the micro-grid.
It should be noted that, the circuit connected to the bidirectional charge-discharge node is a circuit for charging and discharging the energy storage device, such as a storage battery, an electric automobile, etc., and the other circuits connected to the outside are load circuits, such as electric devices in a household power grid, such as a bulb, a water heater, etc.
Therefore, the server can acquire the bidirectional charge and discharge node in the micro-grid where the bidirectional charge and discharge pile is located, and then the micro-grid is divided based on the bidirectional charge and discharge node to obtain an intra-node circuit and an extra-node circuit corresponding to the bidirectional charge and discharge node, wherein the intra-node circuit is a circuit which takes the bidirectional charge and discharge node as a starting point and wants to extend to an end node, and the extra-node circuit is a circuit except the intra-node circuit in the micro-grid.
In some embodiments, in step S1 (obtaining a bidirectional charge-discharge node in a micro-grid where the bidirectional charge pile is located, dividing the micro-grid based on the bidirectional charge-discharge node, and obtaining an intra-node circuit and an extra-node circuit corresponding to the bidirectional charge-discharge node), the method includes S11-S13:
And S11, determining a mains connection point of the micro-grid, sequentially extending to all end nodes of the micro-grid based on the mains connection point as a starting point, and stopping extending when the extension is judged to be the end nodes or the bidirectional charge and discharge nodes.
The utility power connection point is a grid connection point for connecting the micro-grid with the utility power network.
It is to be understood that the lines connected to the bidirectional charge and discharge nodes are lines that can be charged and discharged, and the rest of the lines in the micro-grid are load lines that need to consume electric energy.
Therefore, the utility power connection point of the micro-grid is determined first, and then the utility power connection point is used as a starting point to sequentially extend to all end nodes of the micro-grid, namely, to extend to all power-using devices in the micro-grid line in the direction of power supply of the utility power until the utility power connection point extends to the end nodes, such as power supply sockets corresponding to electric devices such as electric lamps, or the extension is stopped when the utility power connection point extends to the bidirectional charge-discharge node, and then the circuit of all the electric devices is traversed. The end node corresponding to the mains supply connection point as the starting point may be a power supply socket corresponding to the power supply device.
And S12, adding a first mark to the lines extending to the end node or the bidirectional charge-discharge node, and counting all the lines with the first mark to obtain an external node circuit.
It will be appreciated that the server will add the first tag to the lines extending to the end node or the bi-directional charge-discharge node starting from the mains connection point and count all the lines of the first tag to obtain the off-node circuit.
S13, taking the bidirectional charge and discharge node as a starting point again, extending towards the end node until reaching the end node, adding second marks to the corresponding lines, and counting all the lines with the second marks to obtain the intra-node circuit.
It can be understood that, the bidirectional charge and discharge node is taken as a starting point, and extends towards the end node until reaching the end node, and a second mark is added to the corresponding circuit, that is, the bidirectional charge and discharge node is taken as the starting point, to add the second mark to the circuit for supplying power to the energy storage devices such as the storage battery, the electric automobile and the like, wherein the end node corresponding to the bidirectional charge and discharge node which is taken as the starting point can be a conversion socket corresponding to charge and discharge.
And then, counting all the lines marked by the second marks to obtain the intra-node circuit.
S2, receiving energy storage equipment which is respectively configured for circuits in the nodes by users, wherein the energy storage equipment comprises fixed energy storage equipment and non-fixed energy storage equipment, receiving load equipment which is respectively configured for circuits outside the nodes by users, and monitoring and processing the fixed energy storage equipment, the non-fixed energy storage equipment and the load equipment to obtain monitoring data.
The energy storage device may be a storage battery, an electric vehicle, or the like, which may be charged and discharged, and the energy storage device includes a fixed energy storage device, for example, the fixed energy storage device may be a storage battery, and an unfixed energy storage device, for example, the unfixed energy storage device may be an electric vehicle.
Further, the server receives load devices configured by the user on the external circuits of the nodes respectively, and monitors and processes the fixed energy storage devices, the non-fixed energy storage devices and the load devices to obtain monitoring data.
In some embodiments, in step S2 (receiving the energy storage devices configured by the user for the circuits in the node, where the energy storage devices include a fixed energy storage device and an unfixed energy storage device, receiving the load devices configured by the user for the circuits outside the node, and performing monitoring processing on the fixed energy storage device, the unfixed energy storage device, and the load devices to obtain monitoring data) includes S21-S23:
S21, receiving energy storage equipment configured by a user for circuits in the nodes, wherein the energy storage equipment at least comprises fixed energy storage equipment which is a storage battery and non-fixed energy storage equipment which is an electric vehicle.
It will be appreciated that the in-node circuit is a circuit that can be charged and discharged, and therefore, the server receives energy storage devices configured by the user for the in-node circuit, respectively, the energy storage devices including at least a fixed energy storage device that is a storage battery, and at least a non-fixed energy storage device that is an electric vehicle.
S22, receiving load equipment configured by a user on the external circuit of the node respectively, and extracting load labels of the load equipment.
It will be understood that, similarly, the user may configure a corresponding load device, such as a home electric device, an electric lamp, a computer, etc., for an external circuit of the node, and extract a load tag of each load device, where each load device has a corresponding device tag, such as device 1 and device 2, and then determine an electricity consumption condition of the corresponding load device according to the corresponding device tag, where the load tag is a tag corresponding to each load, and then the subsequent user may determine an electricity consumption condition of each load according to the load tag, so as to perform targeted adjustment.
S23, monitoring and processing the fixed energy storage equipment, the non-fixed energy storage equipment and the load equipment based on the detection unit to obtain fixed energy storage information, non-fixed energy storage information and corresponding load information.
It is to be understood that the fixed energy storage device, the non-fixed energy storage device and the load device are monitored and processed by the detection unit, so as to obtain the fixed energy storage information, the non-fixed energy storage information and the corresponding load information. The load information is electric quantity use information monitored by the fixed energy storage equipment, the non-fixed energy storage equipment and the load equipment.
And S3, acquiring the electricity utilization habit of the micro-grid corresponding to the user, and determining the user use strategy based on the monitoring data and the electricity utilization habit.
It should be noted that, a fixed scheduling policy is often adopted in the conventional micro-grid, and the relationship between the electricity utilization habit of the user, the load device and the energy storage device is not considered, so that the operation of the micro-grid is difficult to reach the optimal state.
Therefore, the method and the device can acquire the electricity utilization habit of the micro-grid corresponding to the user, and then determine the user use strategy based on the monitoring data and the electricity utilization habit.
In some embodiments, in step S3 (obtaining the electricity usage habits of the corresponding micro-grid of the user, determining the user usage policy based on the monitoring data and the electricity usage habits), S31-S33 are included:
S31, based on electricity utilization rules in electricity utilization habits, available combination time and available combination electric quantity of fixed energy storage information and non-fixed energy storage information are determined, and data combination is performed, so that energy storage function information is obtained.
It should be noted that, the bidirectional charging pile may perform charging and discharging, for example, charging the energy storage device in a valley period with a lower electricity price, and discharging the energy storage device in a peak period with a higher electricity price. Therefore, for the bidirectional charge and discharge node in the micro grid, only the charge or discharge is performed in the corresponding period.
Moreover, as work and life work and rest of different users are different, the time period of using the electric vehicle by the user is different, the time period of discharging after parking is also different, and the charging and discharging habits of different users are different.
The available combined time is the time for discharging, and the available combined electric quantity is the electric quantity discharged in the time for discharging.
Therefore, the invention can determine the available combination time and the available combination electric quantity of the fixed energy storage information and the non-fixed energy storage information based on the electricity utilization rule in the electricity utilization habit and perform data combination to obtain the energy storage function information. The energy storage function information is obtained by carrying out statistical combination on the discharge amount of the energy storage device in each time period, wherein the electricity utilization rule can be the electricity utilization habit of a user during the discharge period of the energy storage device.
In some embodiments, in step S31 (determining the available combination time and the available combination power of the fixed energy storage information and the non-fixed energy storage information based on the electricity usage rule in the electricity usage habit and performing data combination to obtain the energy storage function information), the method includes S311-S314:
s311, acquiring fixed energy storage time and fixed energy storage electric quantity of the fixed energy storage device in a user-controlled energy storage scene, and acquiring non-fixed energy storage time and non-fixed energy storage electric quantity of the non-fixed energy storage device in the user-controlled energy storage scene.
It can be appreciated that the server may obtain the fixed energy storage time and the fixed energy storage power of the fixed energy storage device in the user controlled energy storage scenario, that is, may obtain the discharge time and the corresponding discharge power of the fixed energy storage device in the micro-grid based on the habit of the user.
For example, if the micro-grid is discharged from the storage battery from 9 am to 9 pm based on the habit of the user, the fixed energy storage time is from 9 am to 9 pm, and the amount of electricity discharged from the storage battery from 9 am to 9 pm is counted as the fixed energy storage amount.
And similarly, the non-fixed energy storage time and the non-fixed energy storage electric quantity of the non-fixed energy storage device in a user-controlled energy storage scene can be obtained. That is, the discharge time and corresponding discharge amount of the non-stationary energy storage device in the micro grid may be obtained based on the habit of the user.
Through the embodiment, the power grid can be discharged in the peak time and the energy storage equipment can be charged in the valley time, so that the power grid stability is improved and the expenditure can be reduced.
S312, dividing the fixed energy storage time based on a preset time period to obtain a plurality of fixed energy storage sub-time periods, and counting the fixed energy storage sub-information of the fixed energy storage information under each fixed energy storage sub-time period.
The preset time period may be a manually preset time period, for example, 1 hour.
Therefore, the invention divides the fixed energy storage time based on the preset time period to obtain a plurality of fixed energy storage sub-time periods, for example, the fixed energy storage sub-time periods are divided from 9 in the morning to 9 in the evening for 1 hour to obtain 12 time periods.
Subsequently, the fixed energy storage sub-information of the fixed energy storage information under each fixed energy storage sub-time period is counted, that is, the discharge amount corresponding to each fixed energy storage sub-time period is counted, for example, the discharge amount of the storage battery from 9 a.m. to 10 a.m. is counted.
S313, dividing the non-fixed energy storage time based on a preset time period to obtain a plurality of non-fixed energy storage sub-time periods, and counting the non-fixed energy storage sub-information of the non-fixed energy storage information under each non-fixed energy storage sub-time period.
It can be understood that, similar to the principle of step S312, the present invention performs a segmentation process on the non-fixed energy storage time based on a preset time period to obtain a plurality of non-fixed energy storage sub-time periods, and counts the non-fixed energy storage sub-information of the non-fixed energy storage information under each non-fixed energy storage sub-time period. Namely, the discharge capacity of the electric vehicle in each non-fixed energy storage sub-period can be obtained later.
And S314, obtaining energy storage function information based on the combination of the fixed energy storage sub-information under each fixed energy storage sub-time period and the non-fixed energy storage sub-information under each non-fixed energy storage sub-time period.
It can be understood that the subsequent server can obtain the energy storage function information based on the combination of the fixed energy storage sub-information under each fixed energy storage sub-period and the non-fixed energy storage sub-information under each non-fixed energy storage sub-period. That is, the power applications corresponding to each time period are combined and connected later, so that energy storage function information is obtained.
In some embodiments, in step S314 (the energy storage function information is obtained based on the fixed energy storage sub-information under each fixed energy storage sub-period and the non-fixed energy storage sub-information under each non-fixed energy storage sub-period) includes S3141-S3144:
S3141, constructing a corresponding function coordinate system based on a preset time period, wherein the abscissa of the function coordinate system is a plurality of periodic points corresponding to the preset time period, and each periodic point corresponds to a fixed energy storage sub-period and a non-fixed energy storage sub-period.
It can be understood that the server constructs a corresponding function coordinate system based on the preset time period, where the abscissa of the function coordinate system is a plurality of periodic points corresponding to the preset time period, for example, 24 periodic points, 24 hours a day, so that the corresponding periodic points of each hour are constructed in the function coordinate system. Each cycle point corresponds to a fixed energy storage sub-period and an unfixed energy storage sub-period. It is understood that 24 hours a day, for discharging the storage battery and the electric vehicle, there may be a period of simultaneous discharge, and if there is no discharge, the discharge amount corresponding to the period may be 0, and the ordinate of the function coordinate system may be the electric quantity.
S3142, determining a fixed coordinate point based on the periodic point and the fixed energy storage sub-information corresponding to each fixed energy storage sub-time period, and determining an unfixed coordinate point based on the periodic point and the unfixed energy storage sub-information corresponding to each unfixed energy storage sub-time period.
It will be appreciated that the server will determine the fixed coordinate point based on the periodic point and the fixed energy storage sub-information corresponding to each fixed energy storage sub-period. For example, if the discharge amount from 9 a.m. to 10 a.m. is 10KWh, a fixed coordinate point is determined at the position of 10 a.m. on the abscissa and at the position of 10KWh on the ordinate. Similarly, the server determines the non-fixed coordinate point based on the periodic point and the non-fixed energy storage sub-information corresponding to each non-fixed energy storage sub-period.
S3143, adding the fixed energy storage sub-information and the non-fixed energy storage sub-information corresponding to the same period point to obtain combined sub-information, and determining a combined coordinate point.
It will be appreciated that the server will add the fixed energy storage sub-information and the non-fixed energy storage sub-information of the same periodic point to obtain combined sub-information and determine a combined coordinate point. For example, the fixed energy storage sub-information and the non-fixed energy storage sub-information of the position of the 10-point on the abscissa are added to obtain combined sub-information, for example, the electric vehicle is discharged for 10KWh, the combined sub-information is 20, and the combined coordinate point is determined according to the 10-point on the abscissa and the 20-point on the ordinate.
And S3144, obtaining energy storage function information based on the combination of the fixed coordinate points, the non-fixed coordinate points and the combined coordinate points.
It is understood that the server may obtain the energy storage function information based on the combination of the fixed coordinate point, the non-fixed coordinate point and the combined coordinate point, that is, the energy storage function information is obtained when 3 discharge curves are displayed in the coordinate system at the same time, and the discharge curves of the combined battery and the electric vehicle are displayed at the same time.
In some embodiments, in step S3144 (obtaining energy storage function information based on the fixed coordinate point, the non-fixed coordinate point, and the combined coordinate point combination) includes:
And connecting all the fixed coordinate points based on the first connecting line to obtain a fixed energy storage subfunction.
It is to be understood that the fixed coordinate point may be a discharge coordinate point corresponding to the battery, and thus the fixed coordinate point is connected based on the first connection line to obtain the fixed energy storage sub-function.
And connecting all the non-fixed coordinate points based on the second connecting line to obtain a non-fixed energy storage subfunction.
It is to be understood that the non-fixed coordinate point may be a discharge coordinate point corresponding to the electric vehicle, so that the non-fixed coordinate point is connected based on the second connecting line to obtain the non-fixed energy storage sub-function.
And connecting all the combined coordinate points based on a third connecting line to obtain a combined energy storage subfunction.
It is to be understood that, consistent with the principle of determining the fixed energy storage subfunction and the non-fixed energy storage subfunction, all the combined coordinate points are connected based on the third connecting line to obtain the combined energy storage subfunction.
And respectively configuring the fixed coordinate point, the non-fixed coordinate point and the combined coordinate point as selectable midpoints, and obtaining energy storage function information based on the fixed energy storage subfunction, the non-fixed energy storage subfunction and the combined energy storage subfunction.
It should be noted that, the fixed coordinate point, the non-fixed coordinate point and the combined coordinate point are all discharge conditions of the energy storage device under the electricity utilization habit of the user, and the electricity utilization condition is relatively regular, so that the fixed coordinate point, the non-fixed coordinate point and the combined coordinate point are respectively configured as selectable midpoints, that is, all the fixed coordinate point, the non-fixed coordinate point and the combined coordinate point are set as adjustable points, then the discharge quantity corresponding to each periodic point can be adjusted according to the requirement of a person, that is, the user views the predicted change condition adapting to the requirement of the user, if one coordinate point is adjusted in the history, the other coordinate point or multiple coordinate points can be adjusted according to the original function, and accordingly, the whole change condition can be seen, and the user can select corresponding periodic points to customize and move downwards according to the requirement of the user, so as to reduce the discharge quantity, and limit the discharge quantity set by the user in the subsequent operation process.
It can be understood that the server configures the fixed coordinate point, the non-fixed coordinate point and the combined coordinate point as optional middle points respectively, wherein the optional middle points are coordinate points which can be adjusted, that is, a user can automatically adjust and watch each coordinate point, and energy storage function information is obtained based on the fixed energy storage sub-function, the non-fixed energy storage sub-function and the combined energy storage sub-function.
On the basis of the embodiment, the method further comprises the steps of A1-A6:
A1, determining all acquisition time points in an acquisition time period by taking the current time as a starting point, and acquiring energy storage function information of each acquisition time point, wherein the time of each acquisition time point is 1 day.
The collection time period is a historical collection day, such as 3 days, today, yesterday and previous days. The current time may be today.
Therefore, the server determines all the acquisition time points in the acquisition time period by taking the current time as a starting point, and acquires the energy storage function information of each acquisition time point, namely, acquires an energy storage function curve of 3 days, wherein the time of each acquisition time point is 1 day.
And A2, calculating the combined difference value of the combined coordinate points of all the energy storage function information under each same period point, and determining the point with the largest combined difference value as a numerical offset point.
It can be understood that the server calculates the combined difference value of the combined coordinate points of all the energy storage function information at each same period point, and determines the point with the largest combined difference value as the numerical offset point of the electric quantity differentiation. That is, a combined coordinate point with the largest difference in discharge amount within 3 days is calculated as the offset point of the electric quantity differentiation with the largest difference in value, that is, the offset point with the largest electric quantity change in value in a period of time is shown to the user.
A3, acquiring energy storage function information of all acquisition time points, calculating the average value to obtain energy storage function information after average value calculation, and obtaining an electric quantity difference value according to the electric quantity information of the energy storage function information corresponding to the combined coordinate point and the electric quantity information of the energy storage function information corresponding to the combined coordinate point after average value calculation at the same period point.
It can be understood that the server can acquire the energy storage function information of all the acquisition time points and perform mean value calculation to obtain the energy storage function information after mean value calculation, that is, perform mean value calculation on the discharge amounts corresponding to the periodic points within 3 days and connect the discharge amounts, so as to obtain the energy storage function information after mean value calculation.
And then, obtaining an electric quantity difference value according to the electric quantity information of the combined coordinate point corresponding to the energy storage function information and the electric quantity information difference value of the combined coordinate point corresponding to the energy storage function information after the average value calculation at the same period point.
And A4, judging that the electric quantity difference value is larger than a preset difference value, and taking the corresponding combined coordinate point as a coordinate offset point.
The preset difference is a manually preset difference, such as 20kWh.
It can be understood that a difference value, for example, 20kWh, is preset by the server, and if the difference value of the electric quantity is determined to be greater than the preset difference value, the combined coordinate point corresponding to the corresponding energy storage function information is used as the offset point. That is, the offset point on the coordinate system is determined in all the combined coordinate points in the energy storage function information, that is, when the difference between the electric quantity information of the energy storage function information and the average electric quantity information is too large at the periodic point corresponding to a certain acquisition time period, the combined coordinate point is taken as the coordinate offset point.
And A5, if judging that one coordinate offset point is not directly connected with other coordinate offset points, amplifying the coordinate offset point by a preset multiple, and then connecting the coordinate offset point as a starting point with an adjacent combined coordinate point.
It should be noted that the present invention then finds that the coordinate offset point is significantly different from the average electric quantity value. A problem of great fluctuation occurs at this point in time and thus it is amplified. After amplification, the power grid is connected with the point of the adjacent time, so that the power grid is highlighted, a person can conveniently and directly check the unstable power grid at the point of time, the electric quantity demand is large, then the subsequent person can add the storage battery capacity, and then the person can use cheap electric energy or save the electric energy even if the deviation amplitude is large.
It will be appreciated that if one coordinate offset point is not directly connected to another coordinate offset point, it is indicated that the offset is larger at this point only at this hour, and no larger offset occurs at the adjacent time, so the invention will amplify the offset point by a preset multiple and then connect the offset point as a starting point to the adjacent combined coordinate point. A highlighting of this point in time is achieved.
And A6, determining the pixel value of each pixel point in a connecting line between the coordinate offset point and the combined coordinate point based on the first pixel value of the coordinate offset point, the second pixel value of the combined coordinate point and the number of the pixel points between the coordinate offset point and the combined coordinate point, wherein the pixel values from the coordinate offset point to the combined coordinate point are in gradient change.
It will be appreciated that the coordinate offset point is the amount of power corresponding to a time period. And illustrates that the deviation of the power consumption is large in this period, but the adjacent time is normal, i.e. the coordinate shift point is an irregular behavior, at which point we can set this point to red. The adjacent combined coordinate points are set to be normal green, and the time difference between the electricity consumption and the periphery is not too great normally, so that the connecting line between the red coordinate offset point and the green combined coordinate points can be in gradually changing color, namely, the connecting line can be gradually faded from red to green, and the color changing function of the connecting line is realized.
Subsequently, the user can actively move the coordinate offset point to enable the coordinate offset point to be close to the adjacent combined coordinate point, and the color of the connecting line is gradually changed from red to green as the coordinate offset point is close to the adjacent combined coordinate point. That is, the pixel values from the coordinate offset point to the combined coordinate point are changed in a gradient.
The first pixel value and the second pixel value are preset pixel values, so that personnel can conveniently and intuitively check and distinguish a normal time period and an abnormal time period, and then the pixel value of each pixel point in a connecting line between the coordinate offset point and the combined coordinate point is respectively determined according to the number of the pixel points of the connecting line between the coordinate offset point and the combined coordinate point.
For example, the difference between the RGB values of the first pixel value and the second pixel value is an RGB set value, and at this time, the number of pixels is 100, and then each RGB element in the corresponding RGB set value is divided by 100 to obtain a color difference group between the pixel values of two adjacent pixels, and the pixel value corresponding to each pixel between the offset endpoint and the combined coordinate point is obtained at this time according to the corresponding color difference group and the positional relationship between each pixel and the offset endpoint or the combined coordinate point. For example, the offset endpoint coordinate has an R value ofG value isB is ofR value of combined coordinate point isG value isB is ofThe RGB aggregate value isThe color difference group isAt this time, the pixel value of the coordinate point adjacent to the offset endpoint coordinate isThe color gradually changes gradually due to gradual decrease, and when a coordinate offset point is moved by a person to be close to an adjacent combined coordinate point, the color gradually changes to green and returns to normal.
On the basis of the embodiment, the method further comprises the steps of A7-A9:
And A7, if judging that one coordinate offset point is directly connected with other coordinate offset points, connecting the adjacent coordinate offset points to obtain a coordinate offset line, and determining the end points on two sides of the coordinate offset line to obtain two coordinate offset end points.
It is to be understood that if it is determined that one coordinate offset point is directly connected with other coordinate offset points, it is indicated that the points of the coordinate offset point corresponding to adjacent times have large deviations, at this time, the adjacent coordinate offset points are connected to obtain a coordinate offset line, and the end points on both sides of the coordinate offset line are determined to obtain two offset end points.
And A8, respectively amplifying the coordinate offset endpoints by preset times, and respectively connecting the coordinate offset endpoints with adjacent combined coordinate points as starting points.
It can be understood that the offset end points are respectively amplified by preset times and then respectively used as starting points to be connected with the adjacent combined coordinate points. Similar to the previous steps, the method is a time period for checking the abnormality for the convenience of personnel.
And A9, determining the pixel value of each pixel point in a connecting line between the coordinate offset endpoint and the combined coordinate point based on the first pixel value of the coordinate offset endpoint, the second pixel value of the combined coordinate point and the number of the pixel points between the coordinate offset endpoint and the combined coordinate point, wherein the pixel values from the coordinate offset endpoint to the combined coordinate point are in gradient change.
In the same way, the principle is consistent with the principle of the step A6, in order to embody an abnormal time period, the charge capacity of a corresponding time period is conveniently increased later, or the electric quantity is saved in the time period, namely, the electric quantity is saved, or the charge capacity is increased, so that the pixel value of each pixel point in a connecting line between an offset point and a combined coordinate point is determined through the first pixel value of the offset endpoint, the second pixel value of the combined coordinate point and the pixel point number between the offset endpoint and the combined coordinate point, the pixel value from the offset point to the combined coordinate point is in gradient change, the color display gradual change is realized, and the normal state is recovered. For example, the difference between the RGB values of the first pixel value and the second pixel value is an RGB set value, and at this time, the number of pixels is 100, and then each RGB element in the corresponding RGB set value is divided by 100 to obtain a color difference group between the pixel values of two adjacent pixels, and the pixel value corresponding to each pixel between the offset endpoint and the combined coordinate point is obtained at this time according to the corresponding color difference group and the positional relationship between each pixel and the offset endpoint or the combined coordinate point. For example, the offset endpoint coordinate has an R value ofG value isB is ofR value of combined coordinate point isG value isB is ofThe RGB aggregate value isThe color difference group isAt this time, the pixel value of the coordinate point adjacent to the offset endpoint coordinate is。

Namely, the difference between the total discharge and the total power consumption is calculated, so that the electric energy difference is obtained.
S333, if the electric energy difference value is less than or equal to 0, counting the corresponding time for generating the combined power utilization habit at all moments.
It can be understood that if the electric energy difference is less than or equal to 0, it indicates that the load has larger electric consumption and insufficient power supply, and that additional mains supply is needed to supply power at this time, the time of generating the combined power consumption habit at all corresponding moments is counted, where the time of the combined power consumption habit is the time corresponding to the combined power supply.
And S334, if the electric energy difference value is greater than 0, counting the corresponding time for generating the reverse electricity utilization habit at all moments.
