如今，分散式风电、屋顶光伏、储能、三联供、电动汽车、柔性负荷等分布式资源的大规模并网，为配电网的安全稳定运行与集中管理带来一系列的影响，使配电网呈现出结构复杂、设备多元、技术庞杂的特点。分布式资源具有量大、分散、不确定性大等一系列不利于配电网调控的特点，依靠现有的调控方法，难以实现分布式资源的实时监控和高效有序的管控。Today, the large-scale grid connection of distributed resources such as distributed wind power, rooftop photovoltaics, energy storage, triple supply, electric vehicles, and flexible loads has brought a series of impacts on the safe and stable operation and centralized management of the distribution network. The power grid presents the characteristics of complex structure, diverse equipment and complex technology.

图1是本发明一种实施方式提供的配电网云边端协同管控系统的系统结构图。如图1所示，本发明实施方式提供一种配电网云边端协同管控系统，所述系统包括：树状网连接的自治控制终端、聚合协同装置和中心云；其中，所述中心云为一级节点，所述聚合协同装置为次级节点，所述自治控制终端为末级节点；所述中心云连接有多个聚合协同装置，每个聚合协同装置又连接有多个自治控制终端；所述自制控制终端用于采集对应片区内各并网聚类的资源信息，并根据来自所述聚合协同装置的二级调控指令进行对应并网聚类调控；所述聚合协同装置用于同步连接的所有自治控制终端上发的资源信息，并下发对应的二级调控指令到所有连接的自治控制终端；所述中心云用于同步连接的所有聚合协同装置上发的资源信息，并下发对应的一级调控指令到所有连接的自治控制终端；其中，所述二级调控指令和所述一级调控指令均是基于对应的资源信息生成。FIG. 1 is a system structure diagram of a cloud-side-end collaborative management and control system for a distribution network provided by an embodiment of the present invention. As shown in FIG. 1 , an embodiment of the present invention provides a cloud-side-end collaborative management and control system for a distribution network. The system includes: an autonomous control terminal connected by a tree network, an aggregation coordination device, and a central cloud; wherein the central cloud It is a first-level node, the aggregation coordination device is a secondary node, and the autonomous control terminal is a final-level node; the central cloud is connected to a plurality of aggregation coordination devices, and each aggregation coordination device is connected to a plurality of autonomous control terminals. The self-made control terminal is used to collect the resource information of each grid-connected cluster in the corresponding area, and perform corresponding grid-connected clustering regulation according to the secondary regulation instruction from the aggregation coordination device; the aggregation coordination device is used to synchronize The resource information sent by all connected autonomous control terminals, and the corresponding secondary control instructions are sent to all connected autonomous control terminals; the central cloud is used to synchronize the resource information sent by all connected aggregation and coordination devices, and download the corresponding secondary control instructions to all connected autonomous control terminals; Send the corresponding first-level control instructions to all connected autonomous control terminals; wherein, the second-level control instructions and the first-level control instructions are both generated based on corresponding resource information.

在本发明实施例中，本发明方案根据配电物联网物联体系的云边端协同交互需要，提出一种配电网云边端协同管控方法及系统，提出了自治控制终端、聚合协同装置的基本架构。利用“中心云”+“边缘云”的方式、结合数据采集与处理技术、边缘计算技术、通信技术等，将类内自组织、类间合约协同策略模块部署于自治控制终端内，将聚合、合约协同策略模块设置于聚合协同装置内，实现端侧自组织、端侧与端侧协同、端侧与边侧、边侧与边侧、边侧与云侧协同的管控。其具体实现理念为：In the embodiment of the present invention, the solution of the present invention proposes a cloud-side-end collaborative management and control method and system for a distribution network according to the needs of the cloud-side-terminal collaborative interaction of the power distribution IoT system, and proposes an autonomous control terminal and an aggregation collaboration device. basic structure. Using the method of "central cloud" + "edge cloud", combined with data collection and processing technology, edge computing technology, communication technology, etc., the intra-class self-organization and inter-class contract collaboration strategy modules are deployed in the autonomous control terminal, and the aggregation, The contract collaboration strategy module is set in the aggregation collaboration device to realize the management and control of end-side self-organization, end-side and end-side collaboration, end-side and side-side, side-side and side-side, and side-side and cloud-side collaboration. Its specific realization concept is:

通过树网设置连接自治控制终端、聚合协同装置和中心云，在传统的方法中，中心云需要统筹管理辖区的所有设备单元，本发明方案进行聚类整合，将调控权限进行逐级下方，使得设备侧具有一定的自我调控能力，避免所有调控压力均集中到中心云侧。The autonomous control terminal, the aggregation coordination device and the central cloud are connected through the tree network setting. In the traditional method, the central cloud needs to manage all the equipment units in the jurisdiction in an overall manner. The device side has a certain self-regulation capability to avoid all regulation pressure being concentrated on the central cloud side.

所以，自治控制终端便是设置在设备侧的初级调控装置，其一方面实现其控制范围内的资源信息采集、数据预处理，另一方面将采集的信息处理后及时传输到上级聚合协同装置，接收并执行上级调控命令。所以，自治控制终端具备一定的边缘计算能力，以类为单位，内嵌聚类算法模块与策略模块，能够采用聚类算法对其所调控范围内的资源进行聚类，通过策略模块对下级资源实时分析决策，并对下级资源进行集中管理与协同调控。优选的，为了对分布式资源、柔性负荷、用电用户等资源进行有效区分，将这些类别进行分别整理，每一个自治控制终端进行一个聚类负责。因为同一聚类下的设备用/供电具有一定的相似性，基于这些相似性可以高效率进行信息采集和设备调控。当然，本发明方案并不局限于上述的类别划分，还可以进行进一步的拆解划分，例如划分智能表计、智能电器、电动汽车、光伏发电、风力发电等，只要存在对应的聚类划分，均理论上在本发明方案的保护范围内。Therefore, the autonomous control terminal is the primary control device set on the equipment side. On the one hand, it realizes resource information collection and data preprocessing within its control range, and on the other hand, it processes the collected information and transmits it to the upper-level aggregation coordination device in time. Receive and execute superior control commands. Therefore, the autonomous control terminal has a certain edge computing capability, with the class as the unit, embedded clustering algorithm module and strategy module, can use the clustering algorithm to cluster the resources within its control range, and use the strategy module to cluster the lower-level resources. Real-time analysis and decision-making, and centralized management and coordinated control of subordinate resources. Preferably, in order to effectively distinguish resources such as distributed resources, flexible loads, and electricity users, these categories are sorted separately, and each autonomous control terminal is responsible for one clustering. Because the equipment usage/power supply in the same cluster has a certain similarity, information collection and equipment regulation can be efficiently performed based on these similarities. Of course, the solution of the present invention is not limited to the above-mentioned category division, and further disassembly and division can be carried out, for example, smart meters, smart appliances, electric vehicles, photovoltaic power generation, wind power generation, etc., as long as there are corresponding clustering divisions, All theoretically fall within the protection scope of the solution of the present invention.

聚合协同装置以一定的片区为单元，负责一个片区内的所有自治控制终端，例如以台区为单元。一方面用于同步有效时间内所有自治控制终端传来的信息，同时将所有设备运行信息与状态上传到中心云端进行实时监控，并根据调控需求对下方自治控制终端下发调控指令。另一方面充当边缘云，对其所管辖的自治控制终端进行集中管理与协同调控。The aggregation coordination device takes a certain area as a unit, and is responsible for all autonomous control terminals in one area, for example, a station area as a unit. On the one hand, it is used to synchronize the information from all autonomous control terminals within the valid time, and at the same time upload all equipment operation information and status to the central cloud for real-time monitoring, and issue control instructions to the autonomous control terminals below according to the control requirements. On the other hand, it acts as an edge cloud, and performs centralized management and coordinated regulation of autonomous control terminals under its jurisdiction.

中心云是最高的决策单元，将下级聚合协同装置的信息同步，并对其进行集中管理与调控，协调其管辖范围内的分布式资源、柔性负荷、用电用户等资源的安全稳定运行与合理有序用电，以数据存储、数据分析处理为手段并结合一定的云计算方法，根据配电网的具体需求与目标，实现具体的调控任务。优选的，调控类型包括：协调控制、智能运维、削峰填谷、能量动态平衡、信息发布互动中的至少一种。The central cloud is the highest decision-making unit. It synchronizes the information of lower-level aggregation and coordination devices, and centrally manages and regulates them, coordinating the safe, stable and reasonable operation of distributed resources, flexible loads, electricity users and other resources within its jurisdiction. Orderly use of electricity, using data storage, data analysis and processing as means and combined with certain cloud computing methods, according to the specific needs and goals of the distribution network, to achieve specific control tasks. Preferably, the regulation type includes at least one of coordinated control, intelligent operation and maintenance, peak shaving and valley filling, energy dynamic balance, and information release interaction.

优选的，所述树状网连接关系内，同级节点间存在相互通信关系。Preferably, within the tree network connection relationship, there is a mutual communication relationship between peer nodes.

在本发明实施例中，因为自治控制终端和聚合协同装置均具有一定的边缘计算能力，若仅基于当前片区内的资源信息进行调控方案确定，势必会造成考虑不全面的情况。因为电网连接并非各设备负责的“孤岛”，而是具有互通的连接关系，所以想要实现一定的自治控制终端自我调控能力，或聚合协同装置的协助调控能力，仅依靠其对应负责区域内的资源信息是远远无法实现的。为了使得调控有效，需要各负责区域进行资源共享，基于电网供电特性进行整体的、统筹的调控指令生成。而正是为了便于进行折中资源共享，同级节点间存在相互通信关系。即自治控制终端与其他自治控制终端存在相同通信关系，聚合协同装置与其他聚合协同装置也存在相互通信关系。In the embodiment of the present invention, since both the autonomous control terminal and the aggregation coordination device have certain edge computing capabilities, if the control scheme is determined only based on the resource information in the current area, it will inevitably lead to incomplete consideration. Because the power grid connection is not an "island" that each device is responsible for, but has an interoperable connection relationship, so if you want to achieve a certain self-regulation capability of autonomous control terminals, or the assisted regulation capability of aggregated coordination devices, you only rely on its corresponding responsible area. Resource information is far from achievable. In order to make the regulation effective, each responsible area needs to share resources, and generate an overall and coordinated regulation command based on the power supply characteristics of the power grid. It is precisely for the convenience of compromise resource sharing that there is a mutual communication relationship between peer nodes. That is, the autonomous control terminal and other autonomous control terminals have the same communication relationship, and the aggregation cooperation device and other aggregation cooperation devices also have a mutual communication relationship.

优选的，所有跨级节点间和同级节点间的通信均为无线通信，其通讯规则至少包括：无线公网、载波、光纤中的任意一种。Preferably, all the communications between the inter-level nodes and between the peer-level nodes are wireless communications, and the communication rules include at least any one of a wireless public network, a carrier wave, and an optical fiber.

优选的，每一个自制控制终端对应负责一种并网聚类。Preferably, each self-made control terminal is correspondingly responsible for one kind of grid-connected clustering.

优选的，所述并网聚类包括：分布式资源、柔性负荷、用电用户中的至少一种。Preferably, the grid-connected clustering includes at least one of distributed resources, flexible loads, and electricity users.

优选的，所述各并网聚类的资源信息包括：对应聚类下各设备的电气量信息、温度信息、能效比信息、冷/热功率信息、系统频率信息、用/共电特性信息中的至少一种。Preferably, the resource information of each grid-connected cluster includes: electrical quantity information, temperature information, energy efficiency ratio information, cooling/heating power information, system frequency information, power usage/common electricity characteristic information of each device under the corresponding cluster at least one of.

在本发明实施例中，自治控制终端的聚类主要为同质聚类，同质指的是采集的数据类型相同的资源，主要目的是为了提取具有相同用电特性、发电特性或参与削峰填谷次数、参与削峰填谷容量、参与削峰填谷时段等相同的同质资源，便于同类资源的统一特性分析及分级调控。具体的，例如：In the embodiment of the present invention, the clustering of autonomous control terminals is mainly homogeneous clustering. Homogeneous refers to the collected data of the same type of resources, and the main purpose is to extract the same power consumption characteristics, power generation characteristics or participate in peak shaving. The same homogeneous resources, such as the number of times of valley filling, the capacity of participating in peak shaving and valley filling, and the time period of participating in peak shaving and valley filling, are convenient for unified characteristic analysis and hierarchical regulation of similar resources. Specifically, for example:
