Abstract

The invention discloses a power dispatching method and device for a power grid containing an energy storage system and dispatching equipment. The power dispatching method for the power grid containingthe energy storage system comprises the steps of building a target function for power dispatching of the power grid with the target of operation profit maximization of a power generation system of the power grid according to power dispatching parameters of the power grid; solving the target function to obtain an optimal solution for the operation profit of the power generation system; and obtaining a dispatching optimization scheme of the power grid and transmitting the dispatching optimization scheme to an integrated control system according to the optimal solution for the operation profit of the power generation system, thereby carrying out dispatching control on power generation work of the power generation system and power supply work of the energy storage system through the integrated control system according to the dispatching optimization scheme. According to the power dispatching method for the power grid, the power grid can accurately dispatch electric energy from the energystorage system and the operation income of the power grid can be improved.

Description

technical field [0001] The invention relates to the technical field of electric power dispatching, in particular to a dispatching method, device and dispatching equipment for electric power of a power grid including an energy storage system. Background technique [0002] In recent years, the energy industry's awareness of energy storage has been continuously improved, and its application has become more and more extensive. The national recognition and support for the energy storage industry can be seen from multiple policies such as the reform of the electricity market and the outline of the "13th Five-Year Plan". Since 2017, various provinces have successively issued new policies for power auxiliary services, bringing opportunities for energy storage systems to participate in power auxiliary services. [0003] The participation of energy storage systems in power auxiliary services of the power grid can promote the development of the power auxiliary service market and effec...
