Study on the Impact of Charging/Discharging Strategy of Electric Vehicles on Voltage Level of Active Distribution System Considering Multi-period and Variable Correlations
摘要
Abstract
Aiming at the voltage surge problem of active distribution system caused by electric vehicle (EV) charging/discharging,using the probabilistic load flow (PLF) tool the paper discusses the impact of the charging/discharging strategy of EV on the voltage level of active distribution system considering multi-period and variable correlations.Firstly,in view of the performance of EV in different periods,the uncoordinated charging model,controlled charging model and controlled charging/discharging model of EV were proposed to represent the influence of EV on the system voltage.Secondly,Nataf transformation combined with elementary transformation (ET) was used to transform the correlated wind speeds from the correlated non-normal random vector space (CNNRVS) to the independent standard normal random vector space (ISNRVS).Further,ET was employed to transform the correlated loads from the correlated standard normal random vector space (CSNRVS) to the ISNRVS.In turn,the PLF model and algorithm considering the correlated variables were presented to achieve the study on the impact of charging/discharging strategy of EVs on voltage level of active distribution system considering multi-period and variable correlations.Finally,the modified IEEE 33-bus active distribution system was analyzed,and the simulation results show that the controlled charging/discharging strategy of EV can effectively improve the level of voltage stability.关键词
