Abstract

A considerable amount of electricity is additionally demanded for Electric Vehicle (EV) charging due to rapid EV penetration. This study explores the impact of time of charging for different levels of passenger EV penetration on the electricity system using a case study electricity system with high penetration of renewable energy resources. A simulation approach is proposed to determine the new demand profile due to EV charging. Next, a Mixed Integer Linear Programming model is formulated considering the operation schedules of conventional power plants to mimic the real-time status of the electricity system. Finally, the developed approach considers the different possible interventions of actual EVs available in the market and tries to determine their impact in a renewable energy-dominated electricity system. The results from the study show that it is emission-friendly to encourage night charging rather than day charging for the considered renewable energy-dominated case study electricity system.

乘用电动汽车采用对高可再生资源电网的影响评估

由于电动汽车的快速普及，电动汽车充电需要大量的额外电力。本研究以可再生能源普及率高的电力系统为例，探讨不同电动汽车普及率下充电时间对电力系统的影响。提出了一种仿真方法来确定电动汽车充电引起的新需求曲线。其次，考虑传统电厂的运行计划，建立了一个混合整数线性规划模型来模拟电力系统的实时状态。最后，开发的方法考虑了市场上可用的实际电动汽车的不同可能干预措施，并试图确定它们在可再生能源主导的电力系统中的影响。研究结果表明，在以可再生能源为主导的案例研究电力系统中，鼓励夜间充电而不是白天充电是排放友好的。
