Abstract

With the advantages of high efficiency, environmental protection and energy conservation, the high energy storage system has extensive application prospect, economic operation is becoming a wide concerned issue on microgrid with high temperature energy storage system. By analyzing the microgrid with high temperature energy storage system, based on the characteristics of each micro-source, the model of high temperature energy storage system and economic operation model of the grid-connected microgrid are constructed with time-sharing electricity. The improved immune particle swarm algorithm is used to solve the proposed model, and then field application verifies the effectiveness of model. Results show that the proposed method and model can reach the globally optimal solution of dynamic microgrid, and it is of cost saving and significant economic benefit for high temperature energy storage system to participate in thermal load supplying.
