Microgrid which contains distributed generations has become an important part in the construction of smart grid, due to its flexible, clean and economic energy supply mode. To give full play to the economic and environmental benefits of distributed generations in microgrid, a multi-objective optimal operation model of microgrid is built. A multi-objective particle swarm optimization algorithm with hybridization of sub-populations is introduced and applied to the optimal operation of microgrid. Power generation cost, environmental cost and load rejection compensation cost are used as the sub-objective functions in the simulation example. Simulation results show that the proposed algorithm can solve the multi-objective optimal operation of microgrid effectively.
