摘要

研究了插电式电动汽车不同充电速率对智能电网配电系统电能质量的影响。PEV电池充电器是高功率非线性器件，可以产生大量的电流谐波。pev将成为智能电网运行不可或缺的组成部分，因此必须彻底分析其对电能质量的影响。在解耦谐波潮流分析的基础上，针对典型的大型配电网拓扑结构，对不同的电动汽车充电方案(如时区调度、充电速率和渗透水平)进行了测试。讨论了充电速率对电压分布、基频损耗和谐波损耗、变压器负荷和总谐波畸变的影响。

Power quality of smart grids with Plug-in Electric Vehicles considering battery charging profile

The impact of different battery charging rates of Plug-in Electric Vehicles (PEVs) on the power quality of smart grid distribution systems is studied in this paper. PEV battery chargers are high power nonlinear devices that can generate significant amount of current harmonics. PEVs will be an integral component to the operation of smart grids and therefore their power quality impacts must be thoroughly analyzed. Based on decoupled harmonic load flow analysis, different PEV charging scenarios (e.g., time zone scheduling, charging rate and penetration level) are tested for a typical large distribution network topology. The impacts of PEV charge rate on voltage profile, fundamental and harmonic losses, transformer loading and total harmonic distortions are demonstrated.
