英文摘要：

Conforming to the system operation constraints, the optimization of micro-source outputs of a grid-connected micro-grid was conducted for different objectives, such as total power generation cost and consumption cost minimization, or the environmental benefit maximization. The mathematical model was established for a benchmark micro-grid system suggested by CIGRE which was consisted of a micro-turbine, fuel cells, two photovohaic systems and a flywheel energy storage system. The numerical solution based on particle swarm optimization （PSO） was performed. Optimization results demonstrate the validity and feasibility of the proposed method.
