Embodiment

[0205] 1. Parameter setting

[0206] In order to verify that the present invention is modeled under MATLAB R2014b, and the algorithm package CPLEX12.6.3 is used for calculation, the system hardware environment is Intel Core I5 ​​CPU, 3.30GHz, 8GB memory, and the operating system is Win10 64bit. The improved IEEE89 node system is used for analysis, in which the conventional generator sets are 30 hydroelectric generators, the renewable energy generators are 4 wind turbines and 2 photovoltaic generators. According to the different characteristics of users on the system load side, users are divided into three categories: 50% residential users, 25% industrial users and 25% commercial users. The PBDR strategy is adopted for residential users, and the IBDR strategy is adopted for industrial and commercial users.

[0207] 2. Demand side response

Abstract

The invention discloses a power system spinning reserve capacity optimization method considering supply and demand double-side flexible resources. The method comprises the steps of (1) establishing aprice type demand response model and an excitation type demand response model based on uncertainty of a price elastic coefficient; (2) integrating the price type demand response model and the excitation type demand response model into a day-ahead stage and a real-time stage respectively; and (3) constructing a day-ahead and real-time two-stage robust optimization model by taking the minimum systemoperation cost and the minimum standby capacity calling cost as target functions, and then solving the two-stage robust optimization model to realize capacity optimization. According to the method, the source-load double-end flexible resources are fully mined and comprehensively utilized and scheduled, so that the flexibility of the large-scale clean energy grid-connected system is greatly improved, the absorption capacity of the system clean energy is effectively improved, and a very good solution is provided for participation of demand response in system operation scheduling operation.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for optimizing the spinning reserve capacity of a power system considering flexible resources on both sides of supply and demand. Background technique [0002] With the rapid development of the economy, my country's energy demand and environmental protection awareness continue to increase and improve, and the supply of traditional fossil energy will increasingly fail to keep up with the needs of economic development in developed regions. Distributed energy such as wind power and photovoltaic power generation and water energy have the advantages of less pollution and renewable energy. Making full use of energy such as wind, light, and water is of great significance to solving the problems of resource shortage and environmental pollution in the world today. [0003] At present, thermal power and hydraulic power generation units are often used to provide flexible ca...
