摘要：

针对含有电动汽车负荷的微电网,提出了一种考虑分时电价电动汽车负荷的微电网调度方法。分析了分时电价对电动汽车充电概率影响,进而计算了考虑分时电价的电动汽车负荷;建立了含电动汽车、风力发电、光伏发电、微型燃气轮机和柴油机等多微源及负荷的微电网优化调度模型;采用权重粒子群算法（PSO）求解获取最优调度策略。实验结果表明：所提方法能获取分时电价下含电动汽车负荷的微电网经济调度策略,调度策略有效可行。

Abstract: Aim

ing to the micro-grid containing EV (electric vehicle) load,the scheduling method is proposed for micro-grid, considering the load of time-of-use tariffs. The affections of time-of-use tariffs on charging probability of EVs is analyzed, and then is used to calculate the EVs load. The scheduling model is built for micro-grid including many sources and loads, such as, EVs, wind turbines, photovoltaic cells, micro gas turbines, diesel engines. Based on this model, the weights particle swarm optimization (PSO) is used to search the optimal scheduling policy. The results show that the proposed method can obtain the micro-economic dispatch policy containing time-of-use tariffs of EVs load and the schedulingis effective and feasible.

Key words: Micro-grid, optimal operation, plug-in electric vehicle, time-of-use pricing, particle swarm optimization
