Hybrid energy storage system cluster response frequency modulation market method

Abstract

The invention discloses a hybrid energy storage system cluster response frequency modulation market method. The invention provides a method for a hybrid energy storage system cluster to participate infrequency modulation market declaration and respond to a frequency modulation scheduling instruction in allusion to a frequency modulation auxiliary service market in an electric power spot market environment. According to the method, the hybrid energy storage system forms a cluster, the process of uniformly performing frequency modulation market declaration is described as a mixed integer programming problem, and the condition that the frequency modulation instruction is uncertain and the energy storage capacity is limited is considered; therefore, the declaration scheme is constrained through two extreme scenes of charging required by the frequency modulation instruction in all time periods and discharging required by the frequency modulation instruction in all time periods, and the executability of the declaration scheme is ensured. And linear modeling is performed on each stored energy to reduce integer variables in the model. By solving the mixed integer programming problem, thedeclaration scheme of the cluster, the operation strategy of the next day and the decomposition mode of the frequency modulation instruction are determined, and the problem that the energy storage system is difficult to participate in the frequency modulation market is solved.

Description

technical field [0001] The invention belongs to the technical field of energy storage frequency modulation, and in particular relates to a hybrid energy storage system cluster response frequency modulation market method. Background technique [0002] On the one hand, with the market-oriented reform of the power industry, grid operators will gradually no longer directly own most of the power frequency regulation equipment, but need to obtain it in a market-oriented way, that is, the frequency regulation market. On the other hand, the rapid development of energy storage technology has made it more and more widely used in power systems; as a new type of power supply that can be flexibly configured, energy storage has the characteristics of bidirectional adjustment of active power, fast response speed, and high adjustment accuracy. Existing research and engineering practices have been applied to reduce the output of renewable energy. [0003] CN209046262U discloses a combined e...
