背景技术Background technique
随着电力供需形势的变化和电力市场的改革进程，电力批发市场已经形成分时价格信号，固定的零售峰平谷价格比例难以反映和传到分时的批发市场价格信号和电力供需信号，为了与之匹配而出台的电力市场政策也需要逐步放宽，以适应电力市场改革的需求。为此需要逐步放宽峰平谷价格比例的要求，从一个固定的比例，放宽为峰平谷比例的范围，并对零售用户执行分时价格以实现与批发市场分时价格信号的衔接。同时，需要计算电力零售用户分时结算价格的最优规制比例，在放宽峰平谷比例范围的过程中减少对电力系统运行和电力市场运营的冲击。With the changes in the electricity supply and demand situation and the reform process of the electricity market, the electricity wholesale market has formed a time-of-use price signal. The fixed retail peak-to-valley price ratio is difficult to reflect and transmit to the time-of-use wholesale market price signal and electricity supply and demand signal. In order to match it, the electricity market policy issued also needs to be gradually relaxed to meet the needs of electricity market reform. To this end, it is necessary to gradually relax the requirements of the peak-to-valley price ratio, from a fixed ratio to a range of peak-to-valley ratios, and implement time-of-use prices for retail users to achieve connection with the wholesale market time-of-use price signals. At the same time, it is necessary to calculate the optimal regulatory ratio of the time-of-use settlement price of electricity retail users, and reduce the impact on the operation of the power system and the operation of the power market in the process of relaxing the range of peak-to-valley ratios.
现在缺少对电力零售用户分时结算价格规制比例进行规划的方式。There is currently a lack of ways to plan the regulatory ratio of time-of-use settlement prices for electricity retail users.

申请概述Application Overview
随着电力供需形势的变化和电力市场的改革进程，电力批发市场已经形成分时价格信号，固定的零售峰平谷价格比例难以反映和传到分时的批发市场价格信号和电力供需信号，为了与之匹配而出台的电力市场政策也需要逐步放宽，以适应电力市场改革的需求。为此需要逐步放宽峰平谷价格比例的要求，从一个固定的比例，放宽为峰平谷比例的范围，并对零售用户执行分时价格以实现与批发市场分时价格信号的衔接。同时，需要计算电力零售用户分时结算价格的最优规制比例，在放宽峰平谷比例范围的过程中减少对电力系统运行和电力市场运营的冲击。With the changes in the electricity supply and demand situation and the reform process of the electricity market, the electricity wholesale market has formed a time-of-use price signal. The fixed retail peak-to-valley price ratio is difficult to reflect and transmit to the time-of-use wholesale market price signal and electricity supply and demand signal. In order to match it, the electricity market policy issued also needs to be gradually relaxed to meet the needs of electricity market reform. To this end, it is necessary to gradually relax the requirements of the peak-to-valley price ratio, from a fixed ratio to a range of peak-to-valley ratios, and implement time-of-use prices for retail users to achieve connection with the wholesale market time-of-use price signals. At the same time, it is necessary to calculate the optimal regulatory ratio of the time-of-use settlement price of electricity retail users, and reduce the impact on the operation of the power system and the operation of the power market in the process of relaxing the range of peak-to-valley ratios.
在“用户峰谷价格”的技术领域中，已有大量对于用户峰谷价格计算方法的研究和应用，这些方法均无法解决“逐步放宽零售峰平谷价格比例规制”这一业务场景下的几个痛点：In the technical field of "user peak and valley prices", there have been a lot of research and applications on methods for calculating user peak and valley prices. These methods cannot solve several pain points in the business scenario of "gradually relaxing the regulation of retail peak, flat and valley price ratios":
（1）当前未有方法评估，在固定零售峰平谷价格比例的当前环境下，放宽零售峰平谷价格比例规制的影响。(1) There is currently no method to assess the impact of relaxing the regulation of the retail peak-to-valley price ratio in the current environment where the retail peak-to-valley price ratio is fixed.
（2）当前未有方法评估，在固定零售峰平谷价格比例的当前环境下，如何选择一个合适的比例规制范围，来放宽固定零售峰平谷价格比例的规制。(2) There is currently no method to evaluate how to choose an appropriate ratio regulation range to relax the regulation of the fixed retail peak-to-valley price ratio under the current environment of fixed retail peak-to-valley price ratio.
（3）用户峰谷价格计算方法的研究和应用中，有研究提出，以社会效益最大化等作为目标函数，求解最优化模型得到最优的用户峰谷价格。但这种方法所得到的用户峰谷价格，受限于模型数据获取、模型建立和目标函数描述的精确性，直接用于作为零售峰平谷价格比例规制，实际上有悖于电力市场改革的目标。电力市场改革的目标是，为市场主体留出合适的空间，通过市场主体自主决策来实现价格信号的传导，最终实现供需平衡。(3) In the research and application of user peak-valley price calculation methods, some studies have proposed to use social benefit maximization as the objective function to solve the optimization model to obtain the optimal user peak-valley price. However, the user peak-valley price obtained by this method is limited by the accuracy of model data acquisition, model establishment and objective function description. It is directly used as the regulation of retail peak-valley price ratio, which is actually contrary to the goal of power market reform. The goal of power market reform is to leave appropriate space for market players, realize the transmission of price signals through independent decision-making by market players, and ultimately achieve supply and demand balance.
为了解决上述问题，本申请提供一种最优电力零售用户分时结算价格规制比例的计算方法，主要包括电力市场仿真出清迭代计算、零售分时结算价格比例规制参数组合可行性评估、最优零售分时结算价格比例规制参数组合计算三个环节。In order to solve the above problems, the present application provides a method for calculating the optimal time-of-use settlement price regulation ratio for retail electricity users, which mainly includes three steps: iterative calculation of electricity market simulation clearing, feasibility evaluation of retail time-of-use settlement price ratio regulation parameter combination, and calculation of the optimal retail time-of-use settlement price ratio regulation parameter combination.
（1）在电力市场仿真出清迭代计算中，解决的是，在固定零售峰平谷价格比例的当前环境下，如何根据零售分时结算价格比例规制参数组合，得到一个稳健的电力市场出清结果。(1) In the iterative calculation of electricity market simulation clearing, the problem is how to regulate the parameter combination according to the retail time-of-use settlement price ratio in the current environment of fixed retail peak-valley price ratio to obtain a robust electricity market clearing result.
构建“电力批发市场价格-电力零售市场价格-用户负荷曲线-电力批发市场出清”的价格传导链条，其中：1）“电力批发市场价格-电力零售市场价格”的传导基于市场均衡的假设，在市场均衡的情况下，电力零售市场价格会在价格比例规制的范围内，反映电力批发市场的分时价格信号，根据电力批发市场价格的均值，计算得到电力零售市场价格；2）“电力零售市场价格-用户负荷曲线”的传导考虑不同用电类型、不同地区的用户需求弹性系数计算得到，对不同地区的用户划分为不同类别，主要考虑的是在电力市场出清中的建模需求；3）“用户负荷曲线-电力批发市场出清”的传导，采用电力市场仿真出清技术实现，并设置迭代收敛判断，只采用能收敛的价格比例规制参数组合，减少政策推行过程中的模型风险。A price transmission chain of "wholesale electricity market price-retail electricity market price-user load curve-wholesale electricity market clearing" is constructed, in which: 1) The transmission of "wholesale electricity market price-retail electricity market price" is based on the assumption of market equilibrium. Under market equilibrium, the retail electricity market price will reflect the time-of-use price signal of the wholesale electricity market within the scope of price ratio regulation. The retail electricity market price is calculated according to the mean of the wholesale electricity market price; 2) The transmission of "retail electricity market price-user load curve" is calculated by considering the user demand elasticity coefficients of different electricity consumption types and different regions. Users in different regions are divided into different categories, mainly considering the modeling needs in the clearing of the electricity market; 3) The transmission of "user load curve-wholesale electricity market clearing" is realized by using the electricity market simulation clearing technology, and an iterative convergence judgment is set. Only the price ratio regulation parameter combination that can converge is used to reduce the model risk in the policy implementation process.
（2）零售分时结算价格比例规制参数组合安全性和可行性评估，解决的是，在固定零售峰平谷价格比例的当前环境下，如何量化零售分时结算价格比例规制对电力系统、电力市场的影响。(2) Safety and feasibility assessment of the combination of regulatory parameters for retail time-of-use settlement price ratios. This study aims to quantify the impact of retail time-of-use settlement price ratio regulation on the power system and power market under the current environment of fixed retail peak-valley price ratios.
首先进行直接安全指标的判断，直接安全指标不达标的价格比例规制参数组合不可行，减少政策推行过程中对电力系统和电力市场运行带来的风险。直接安全指标包括：1）电力系统断面约束指标，需要判断放宽比例规制后，是否会由于零售分时价格信号的变动，导致负荷特性的变动，带来电力系统安全运行风险；2）电力市场运营约束指标，需要判断放宽比例规制后，负荷特性的改变是否会令电力市场为了满足安全运行条件而无法在市场交易窗口期内完成出清。First, the direct safety indicators are judged. The price ratio regulation parameter combination that does not meet the direct safety indicators is not feasible, which reduces the risks to the power system and power market operation during the policy implementation process. Direct safety indicators include: 1) power system section constraint indicators. It is necessary to judge whether the change in retail time-of-use price signals will lead to changes in load characteristics after the relaxation of ratio regulations, bringing risks to the safe operation of the power system; 2) power market operation constraint indicators. It is necessary to judge whether the change in load characteristics will make the power market unable to complete clearing within the market trading window period in order to meet the safe operation conditions after the relaxation of ratio regulations.
然后进行间接风险指标的计算。除了上述直接安全指标以外，零售分时结算价格比例规制会通过电网运行、电力市场运行的方式间接造成风险。将直接安全指标和间接风险指标加权计算场景价值系数，进行运行可行性判断，保证所评估的比例规制参数组合安全且可行。Then the indirect risk indicators are calculated. In addition to the above direct safety indicators, the retail time-of-use settlement price ratio regulation will indirectly cause risks through the operation of the power grid and the power market. The direct safety indicators and indirect risk indicators are weighted to calculate the scenario value coefficient, and the feasibility of operation is judged to ensure that the evaluated ratio regulation parameter combination is safe and feasible.
（3）最优零售分时结算价格比例规制参数组合计算，考虑的是，可能存在多种价格规制比例是安全且可行的，如何选择更妥善的一套规制比例投入应用。(3) The calculation of the optimal combination of regulatory parameters for retail time-sharing settlement price ratios takes into account that there may be multiple price regulation ratios that are safe and feasible, and how to select a more appropriate set of regulatory ratios for application.
在最优比例规制参数的选择原则上，并不是采用某个场景下的场景价值系数高的参数，而是考虑参数组合在不同场景下的表现，选择在同样场景价值系数波动率的情况下、价值系数均值较高的参数，作为最优零售分时结算比例规制参数组合。In principle, when selecting the optimal proportion regulation parameters, we do not use parameters with high scenario value coefficients in a certain scenario, but instead consider the performance of parameter combinations in different scenarios and select parameters with higher mean value coefficients under the same scenario value coefficient volatility as the optimal retail time-sharing settlement proportion regulation parameter combination.
在介绍了本申请的基本原理之后，下面将参考附图来具体介绍本申请的各种非限制性实施例。After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.
