【摘要】 智能配电系统的发展使电动汽车得以为电力系统提供频率调节等辅助服务,提出的调频竞标模型建立在电动汽车车主、运营商以及电网调度三方信息交互的基础之上,首先利用车主提供的电动汽车状态参数确定每辆电动汽车在调频时刻的调频潜力,加和所聚集电动汽车的调频潜力得到电动汽车运营商的调频容量及竞标曲线,进而通过调频市场的竞标机制满足电网的调频需求,最后根据中标结果控制相应的电动汽车提供调频服务。仿真结果表明,除了部分出行高峰时期的向上调频信号,电动汽车可以很好地满足调频需求,平抑新能源和负荷波动,并且经济性分析显示电动汽车可以通过为电网主动提供调频服务而获得一定的经济收益。更多还原

【Abstract】 The intelligent power distribution system makes it possible for electric vehicles to provide ancillary services,such as frequency regulation.The regulation bidding model proposed in this paper is based on the two-way information interaction among vehicle owners,aggregator,and grid operator.Firstly,the regulation potential of electric vehicle is determined according to the state parameters from vehicle owner.Based on the regulation potential,the aggregator offers its regulation capacity and bidding curves,and then bids in regulation market to meet the regulation demand.Finally,the aggregator controls the dispatched vehicles to provide regulation services.The simulation results show that electric vehicles can satisfy the regulation command signal to mitigate the fluctuation of distributed generations and loads,except several regulation-up signals during travel peak period.And the economic analysis indicates that electric vehicles can obtain economic profits by active provision of regulation services.更多还原
