Microgrid provides an effective technical approach for distributed generation systems connected to the grid. The optimal operation is an important research topic in the field of microgrid. This paper established a mathematical model for the optimal operation of microgrid composed of several objective functions such as economic cost, environmental benefits and the network loss. And an improved gravitational search algorithm was proposed to settle this optimal problem by the introduction of opposition-based learning mechanism, elite strategy and global memory. Finally, the correctness and feasibility of the proposed method were verified through the simulation.
