Abstract
Optimal configuration of the micro power supply is the basis for ensuring stable and economic operation of the microgrid. In this paper, a micro-grid optimal configuration model of microgrid based on particle swarm optimization (PSO) is proposed. It is studied from the aspects of economy and reliability, and optimized by weight coefficient method to obtain the best micro-power supply under various conditions capacity. In this paper, the micro-power supply capacity under the island operation mode is studied, and the model is solved by particle swarm optimization. The simulation results show the feasibility and correctness of the model and the particle swarm optimization algorithm, and improve the economics and reliability of the microgrid.
