考虑不同电价的电动汽车充电服务最优网格划分
摘要:针对电动汽车(electric vehicle，EV)充电设施的规划问题，提出基于不同电价的最优网格划分方法。首先，从建设成本、运营成本、电网效益、用户效益、充电站效益分析充电设施的经济性。其次，根据功能和行为规律将城市分为五类区域，分区域分析私家车、出租车、公交车的出行规律和充放电规律，对私家车首次出行时刻、出行链、停留时间、出租车载客间隔时间进行概率建模，并考虑电价对用户充放电意愿的影响，建立负荷模型。最后，提出采用蒙特卡洛模拟并结合Voronoi图原理实现最优网格划分的步骤。计算结果表明，通过调整电价，可以引导EV用户放电和有序充电，在用户自身获益的同时，为电网降低峰谷差和运行成本，为充电站提供更高的经济效益。
Abstract：Aiming at the planning of electric vehicle (EV) charging facilities, an optimal grid generation method based on different electricity prices is proposed. Firstly, the economics of charging facilities are analyzed from the perspectives of construction cost, operation cost, power grid benefit, user benefit and charging station benefit. Second, according to the function and behavior rule, cities can be divided into five groups, area, analysis the travel law of private cars, taxis, buses and the rule of the charge and discharge, the private cars for the first time, travel time, travel chain, residence time, the taxi passenger time interval probability modeling, and considering the influence of electricity price on the will of the user, to establish load model. Finally, Monte Carlo simulation and Voronoi diagram principle are used to realize the optimal grid generation. The calculation results show that EV access to the power grid can cut peak load and reduce peak and valley difference. Within a certain range, with the increase of discharge price, the reduction of power network operating cost increases, the revenue from electricity sales increases and the growth slows down, and there is an approximate linear relationship between charging station benefits and valley charging price.
