　　【Abstract】Under the condition of stable operation of the micro grid， further consideration of energy optimization of the micro grid can effectively realize the optimal operation of the micro grid. Therefore， this paper combines membrane computing model with particle swarm optimization （PSO）， and proposes an improved method， called particle swarm optimization based on P system （PSOPS）. Then， the stronger computing power and better optimization ability of PSOPS have been verified through simulation. Finally， the PSOPS is applied to the energy optimization of the micro grid. The calculation results show that the proposed algorithm in this paper is more accurate and reliable than the PSO algorithm. At the same time， it can effectively realize the optimal power generation cost of the micro grid and the optimal pollutant emission control.
