Abstract

The invention discloses a wind power, demand response and compressed air energy storage included power dispatching method. The method comprises that an objective function, including the system operation cost and the system wind abandoning cost, of a day-ahead dispatching fuzzy model of a power system is established; constraint conditions, including system constraint, routine set constraint, demandresponse resource constraint and compressed-air energy-storage power station constraint, of the day-ahead dispatching fuzzy model of the power system are established, output of wind turbines, load predicted output and demand response amount in the constraints are all represented by fuzzy numbers, and system positive and negative standby capacity constraints in system constraints are represented in the form of fuzzy opportunity constraints; the system positive and negative standby capacity constraints in system constraints are made equivalent clearly to obtain a clear equivalency model of day-ahead scheduling of the power system; and optimization software is used to solve a converted scheduling model, and an optimal scheduling scheme of the power system is obtained. It is shown that the method can be used to improve the operational economic performance and wind power absorption rate of the power system.

Description

technical field [0001] The invention belongs to the field of day-ahead optimal scheduling of electric power systems, and more specifically relates to a grid scheduling method including wind power, demand response and compressed air energy storage. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, vigorously developing renewable energy led by wind power has become one of my country's important energy strategies. However, wind power has unfriendly characteristics such as intermittency and uncertainty, and large-scale wind power grid integration will pose severe challenges to the safe and economical operation of the power system. In order to deal with the above problems, many scholars have carried out a lot of research work. Among them, demand response technology and compressed air energy storage technology are recognized as effective ways to solve the problem of large-scale wind power consumption. Therefore, h...
