Abstract

Abstract: In order to reduce the operation cost of multi-station integration, improve the economy of multi-station integration, give full play to the value of energy storage power station, and ensure the economic operation of energy storage power station. In this paper, the life model of energy storage station, the load model of edge data center and charging station, and the energy storage transaction model are constructed. By using the method of two-level optimization and particle swarm optimization algorithm, the optimal operation strategy of energy storage station in the complex scene of multi-function in multi station fusion is proposed. The simulation results show that the optimal operation strategy of energy storage power station is the same rate of charge and discharge in the same continuous period group with the same electricity price; among the groups with different electricity prices, the optimal operation strategy of energy storage power station is determined by the time-sharing electricity price, battery life characteristics and load characteristics of multiple stations. The case study shows that the current simple operation strategy is not the best.

Key words: multi-station integration, energy storage power station, life characteristics, optimal operation, double level optimization
