This paper proposes an electric vehicle (EV) charging management scheme for effective utilization of photovoltaic (PV) power based on an auction mechanism. The proposed scheme coordinates an amount of self-consumption of PV output by shifting the charging period of customers’ EVs, and it reduces PV curtailment caused by voltage rise in low-voltage distribution systems (LVDSs). The auction mechanism is introduced in order to assure both the equity of benefit in each customer and the autonomy that enables customers to voluntarily participate in the EV charging management scheme. The authors perform numerical simulations based on a Japanese distribution system model and evaluate the effectiveness of the proposed scheme. The results show that our proposed scheme reduces the residential operation cost and the PV curtailment in LVDSs without an enhanced communication network even taking into consideration the effects of forecasting errors of electricity demand and PV output, and unexpected disconnection condition of several EVs.

使用拍卖机制的电动汽车充电管理，以减少配电系统中的PV限制

本文提出了一种基于拍卖机制的电动汽车（EV）充电管理方案，以有效利用光伏（PV）功率。拟议的方案通过改变客户电动车的充电时间来协调光伏输出的自耗量，并减少了由低压配电系统（LVDS）的电压上升引起的PV削减。引入拍卖机制是为了确保每个客户的利益公平性和确保客户自愿参与EV充电管理方案的自主权。作者基于日本的配电系统模型进行数值模拟，并评估了该方案的有效性。
