This paper started with operating costs, pollutant emissions and operational risk that by the uncertainty of DG output, and built a multi-objective optimization mode/ of micro-grid operation management in smart grid considering all aspects of the micro-grid system constraints. Then niche multi-objective particle swarm optimization algorithm was used to solve the model with the aim to improve the operation management of micro power. The simulation results show that the proposed multi-objective optimization model of micro-grid operational management can implement the comprehensive consideration of cost, pollution emission and operational risk, especially the influence by DG output fluctuation. The study can effectively promote the micro-grid operation management level and ensure the security of the power supply.
