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。
The development of intelligent power distribution system has enabled electric vehicles to provide auxiliary services such as frequency adjustment for power system. The proposed bid-winning bidding model is based on the interaction among vehicle owners, operators and the dispatching of tripartite information. First, The state parameters of the vehicle determine the FM potential of each EV at the FM moment and add the FM potential of the EV gathered to obtain the FM capacity and bidding curve of the EV operator and then meet the FM demand of the power grid through the bidding mechanism of the FM market. According to the successful bid to control the corresponding electric car to provide FM service. The simulation results show that, except for the upward frequency modulation signals during some peak travel periods, the electric vehicles can meet the demand of FM and stabilize the fluctuation of new energy and load, and the economic analysis shows that EVs can get certain frequency by actively providing FM service to the grid Economy Profit.
