摘要/Abstract

摘要： 大量电动汽车（electric vehicle，EV）无序充放电会对电力系统的安全与经济运行产生不利影响。在此背景下, 提出在动态分时电价环境下, 以削峰填谷和消纳本地光伏（photovoltaic，PV）发电出力为目的的电动汽车分层调度策略。在该策略中，电动汽车充放电计划由用户自主响应分时电价并经本地电动汽车调度机构调整后确定。首先, 建立以最大化电动汽车用户效益为目标的电动汽车充放电优化模型。接着, 以消纳本地光伏出力为目标, 发展本地电动汽车调度机构的优化调度模型。之后, 基于实时更新的配电系统预测负荷曲线, 构造动态分时电价更新策略。最后, 采用蒙特卡洛仿真方法模拟电动汽车的出行特性和充电需求, 并以包含3个居民小区的配电系统为例对所提方法的有效性进行了验证。

Abstract: Uncoordinated charging of numerous electric vehicles （EVs） imposes significant negative impacts on the secure and economic operation of the power system concerned. Given this background, a hierarchical scheduling strategy for EVs in a dynamic time-of-use （TOU） tariff environment is proposed with objectives of mitigating load fluctuation and enhancing the local accommodation capability for photovoltaic （PV） power outputs. The charging/discharging schedules are first optimized by EV owners/users, and then adjusted by the local EV dispatcher as final schedules. Specifically, an EV charging/discharging optimization model is first built with objectives of minimizing the charging cost and maximizing the discharging profit. Then, a dispatching model is presented for the local EV operator to enhance the local accommodation capability for PV power outputs. On the basis of the dispatching result of the local EV dispatcher and the on-line updated load profile in the distribution system concerned, a dynamic TOU tariff updating strategy is presented. Finally, On the basis of the EV arrival time, departure time and charging demands generated by the well-established Monte Carlo simulation method, a distribution system with 3 residential communities is employed to demonstrate the effectiveness of the proposed method.

Key words: electric vehicle （EV）, hierarchical scheduling, dynamic time-of-use tariff, EV dispatcher, accommodation capability of photovoltaic （PV） output
