Abstract：The capacity market can provide flexible capacity support for large-scale grid connection of intermittent renewable energy, stimulate the investment of conventional unit power generation capacity, and ensure sufficient reserve capacity during peak load period. In the future spot market environment, the establishment of a suitable capacity market mechanism can guarantee the long-term power supply security in China, so energy storage as a user-side rapid response resource is expected to participate in the capacity market. This paper combined the capacity market, and proposed a user demand response-reservoir regulation (DR-ESS) optimization model from the perspective of users responding to the real-time electricity price of the main energy market and then using the energy storage to achieve optimal power consumption. Firstly, based on the capacity market contract, the user real-time electricity price demand response model is constructed; then the capacity market is considered, the energy storage double-layer optimization configuration model is established, the outer layer optimized the energy storage capacity and capacity, and the inner layer optimized the energy storage charge and discharge strategy. The two-layer model was solved by genetic algorithm and fmincon toolbox respectively. The analysis of a large industrial user data in the PJM market shows that the DR-ESS optimization model can effectively improve the user's economic benefits, realize peak clipping and valley filling, reduce grid investment costs and increase operational reliability.
