Based on the economy, reliability and environmental protection of independent micro-grid operation, a multi-objective optimal configuration model with solar energy, wind energy, micro gas generator and energy storage as distributed power source was established. By analyzing the operating characteristics of the distributed power supply of wind and light storage, the annual temperature, photovoltaic intensity and wind speed are taken as inputs to obtain the optimal configuration scheme of multi-objective of independent micro-grid. To solve the optimization problem, an improved particle swarm optimization algorithm is proposed. The results show that the improved particle swarm optimization algorithm has the advantages of strong global optimal search ability and fast optimization. The effectiveness of the proposed model and the proposed method is verified by simulation analysis.
