需求侧规模化电动汽车的充电负荷优化调控策略

Optimization dispatch control strategy for charging load of large-scale electric vehicle on demand side

针对电力需求侧电动汽车(electric vehicles,EV)用户充电行为的不确定性,分析电动汽车充电负荷调度与控制技术,构建电动汽车充电负荷调控优化模型,提出考虑分时电价与削峰填谷的分层多目标电动汽车充电策略,并对某区域内的1 000辆电动汽车的充电场景进行调控仿真试验。结果表明,本研究提出的优化充电策略能够有效降低充电费用和充电功率峰值,验证了所提出的优化调控策略的有效性。

In view of the uncertainty of the charging behavior of electric vehicle（EV） users,the electric vehicle charging schedule and control technology were analyzed,a model of regulation and optimization for electric vehicle charging load was built,a stratified multi-objective electric vehicle charging strategy considering time-of-use electricity price and peak load shifting was proposed,and a simulation experiment for scheduling control was implemented in charging scenario for 1 000 electric vehicles in a certain area. The results showed that the optimized charging strategy proposed in this study could effectively reduce the charging cost and charging power peak,and verify the effectiveness of the optimization strategy.
