【摘要】 针对电动汽车接入微电网后的经济调度问题,对微电网可分布式电源的出力进行了研究。首先分析电动汽车的行驶特性,在其无序充电负荷模型的基础上,建立了同时考虑电动汽车用户响应度和用户满意度的峰谷分时电价电动汽车有序充放电模型。然后构建一个含电动汽车及风、光、燃气轮机和柴油机的微网系统,以实现微网经济性和环保性运行为双重优化目标,采用改进粒子群算法,来得到不同控制策略下的优化调度结果。仿真结果表明,电动汽车有序充放电,可以有效实现削峰填谷,并且可以在保证良好环境效益的同时提高微网运行的经济性。更多还原

【Abstract】 Based on the economic dispatch problem when the Electric vehicles( EV) perform in Micro-Grid Energy System,the paper researches the output of distributed power supply in Micro-Grid. At the beginning,the driving characteristics are analysed and a orderly charge-discharge EV model which is consideration of peak-valley time-of-use price is built on basis of disorderly charge model at the same time taking into account the responsibility of EV users and customers’ satisfaction. In order to realize the micro network dual optimization goal of economy and environmental,there is a need to build a small micro-grid system including electric cars,a wind turbine,a gas turbine and a diesel engine. Based on the improved particle swarm optimization( pso) algorithm,The paper obtains the optimization of scheduling results under different control strategies. The simulation results show that the orderly charge-discharge EV can effectively achieve the peak cutting and guarantee good environmental benefits as well as improve the micro operation economy of the micro network.更多还原
