Reactive power support managing charging park of PHEV

Due to the extensive influence of hybrid vehicles in recent years, the presence of these components as a part of a smart distribution network seems inevitable. Plug-in Electric Vehicles (PEV) participates in electric power transmission to the network in certain hours of a day within a smart distribution network framework. The major PEV's feature is to reinforce the reactive power of the smart distribution system of the power supply. However, utilizing PEVs under any circumstances cannot have positive effects. For example, unscheduled and random charging may cause voltage fluctuations, increased blackouts due to network overload, very large peaks in power consumption thus deteriorating the reactive power. Therefore, this article examines the reactive power reinforcement in distribution networks as well as alleviating sever voltage fluctuations and overload by adjusting EVs charging. It is shown that a proper strategy for Smart Parks, like STATCOM, can be employed to properly compensate the reactive power and eliminate the voltage fluctuations.
