A model of integrated energy system including wind power,photovoltaic power,gas turbine,refrigerator,boiler and so on is established to solve the optimization scheduling problem of cogeneration system with microgrid.In order to minimize the environmental cost and economic cost,sparrow optimization algorithm is used to optimize particle swarm optimization algo-rithm(PSO)which is used to optimize the scheduling scheme of CHCHP system with microgrid.The proposed algorithm solves the shortcomings of particle swarm optimization algorithm,such as falling into local optimum easily and slow conver-gence speed.The proposed algorithm is tested by function simulation,and the comparison results verify the reliability of the proposed method.Comparing with the traditional particle swarm optimization and other existing schemes,the environmental cost and economic cost of the proposed scheme are the lowest,which verifies the effectiveness of the proposed method.
