摘　　要：高温储能系统以其高效、环保、节能等优点而有着广泛的应用前景,含高温储能系统的微电网经济运行日益引起关注。文中对高温储能系统、风机、光伏电池、蓄电池、微型燃气轮机以及燃料电池组成的微电网进行分析研究,在分时电价以及微网并网运行的环境下,基于各电源功率特性,建立了高温储能系统模型及微网经济运行模型。运用改进免疫粒子群算法进行模型求解,现场应用验证了其有效性,结果表明文中方法可使微网动态运行整体达到最优,高温储能系统参与热负荷供应,可以节省成本,具有显著的经济效益。With the advantages of high efficiency,environmental protection and energy con-servation,the high energy storage system has extensive application prospect,economic opera-tion is becoming a wide concerned issue on microgrid with high temperature energy storage sys-tem. 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 mod-el,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 par-ticipate in thermal load supplying.
