    Abstract: This paper constructed an optimized model of the economic operation of the microgrid to optimize the microgrid for studying different improved particle swarm optimization.It employed many normal random numbers to disturb the speed and evaluation direction of the particle swarm optimization. In addition, it compared the astringency of the evolutional particle swarm optimization and the optimal performance under diverse application environments.This paper takes the example of the solar energy storage microgrid to do the analysis. It verifies the improved effect of the evolutional algorithm. Moreover, it validates the scientificity of optimizing the economic operation of the microgrid.
    Key words: microgrid; improved particle swarm optimization algorithm; normal random number; optimized performance
