Abstract Microgrid is a kind of system that can connect distributed generation to large power grid, which realizes the efficient utilization of energy. Aiming at economic benefit, environmental benefit and comprehensive benefit, the output optimization of distributed generation in the case of microgrid separated from large grid system is studied. Impact of energy storage system access on microgrid operation is analyzed. By introducing linear decreasing inertia weight and asynchronous learning factor, the traditional particle swarm optimization (PSO) algorithm is improved, and the water, light, diesel and storage microgrid model is built for calculation. The output changes of distributed generators under different economic objectives before and after connection of energy storage to the microgrid are analyzed. The typical daily load of a hydropower station in Fujian is taken as the research data, and the rationality and effectiveness of the model and algorithm are verified.
