At present, the reform of power market mechanism provides market environment and policy support for the construction of customer side energy storage power station. Under this environment, the control strategy of customer side energy storage participating in demand response is studied to ensure the friendly interaction between power grid and users. Firstly, the architecture of customer side energy storage system is described, and then the control strategy model of customer side energy storage participating in demand response is established, including the control strategy based on information system demand response. Based on the control strategy of standard modular demand response plan and considering the control strategy of energy storage regulation in different scenarios. Finally, a case study is carried out, and then the effect analysis is carried out. It is found that using advanced communication control technology to cluster control multiple discrete and small - scale customer side energy storage systems, regulate their participation in power demand response, expand the application scenario of customer side energy storage power station, significantly improve the revenue of customer side energy storage system and reduce the energy consumption cost of enterprises.
