Wind Power Utilization Solutions Based on Demand Response and EV Retirement Batteries in New Power Systems

This paper proposes an "energy storage battery + demand response" solution for wind power consumption in a large-scale wind power utilization scenario, where it is difficult to ensure stable and economical operation of the power systems. Firstly, the basic model of each part of the new power system with large-scale wind power access is formed, and the models of three types of demand response behaviors are introduced to obtain the optimal mathematical model. Then, four scenarios are set up for verification and comparative analysis based on real-time data from the supply-demand side of the power system. The results show that the "energy storage battery + demand response" solution can effectively improve system safety and reliability, and can reduce the amount of curtailment wind by up to 3320.47MW, a reduction of 74.34%. Improved system economics compared to single energy storage, with unit supply costs reduced to a maximum of 0.03201$/kWh. The use of retired EV batteries instead of new storage batteries in the configuration of energy storage can further reduce the operating costs of the power system, with a total cost reduction of approximately 2.87%.
