Abstract：Optimal scheduling model of island micro?鄄grid considering maintenance costs，fuel cost，battery loss cost and power loss cost was set up. A kind of micro?鄄grid optimal scheduling method using artificial fish algorithm and particle swarm optimization was proposed. Taking the example of micro?鄄grid system with wind turbine，photovoltaic cell，micro gas turbine and lithium battery，simulated each distributed generation unit’s output power using AFSA?鄄PSO and PSO. The results confirmed that the optimal scheduling method proposed in this paper is right and superior.
