摘要:

针对电动汽车无序充电会导致配变总负荷峰谷差率增加的问题,提出基于峰谷分时电价时区的有序充电策略。建立电动汽车无序充电数学模型,采用蒙特卡罗模拟法估算电动汽车集群的无序充电负荷,以电网总负荷的峰谷差率最小为优化目标,采用遗传算法求解出最佳的谷电价时区。仿真结果表明,与无序充电相比,所提策略使电网总负荷的峰谷差率有效降低,当电动汽车数量为1 000辆、用户响应度为0.9时,有序充电时对应的总用电负荷峰谷差率相比无序充电时降低了14.6%,验证了所提策略的有效性。

Abstract:

Aiming at the problem that the disorderly charging for electric vehicles can lead to an increase in the peak valley difference rate of the total load of the distribution transformer, an orderly charging strategy based on time of use tariff periods is proposed.A mathematical model of disorderly charging for electric vehicles is established.The Monte Carlo simulation method is used to estimate the disorderly charging load of the electric vehicle cluster.With the goal of minimizing the peak valley difference rate of the total load of the power grid, the genetic algorithm is used to solve the optimal valley tariff period.The simulation results show that compared with disorderly charging, the proposed strategy effectively reduces the peak valley difference rate of the total load of the power grid.When the number of electric vehicles is 1 000 and the user response is 0.9, the peak valley difference rate of the total electricity load corresponding to orderly charging is reduced by 14.6% compared with disorderly charging, which verifies the effectiveness of the proposed strategy.

Key words: peak valley difference, orderly charging, electric vehicles, charging strategy, time of use tariff
