تجزیه و تحلیل و کاهش اثرات پلاگین در وسایل نقلیه الکتریکی در سیستم توزیع در طول گسل
Abstract: With rising concerns for environment, energy security and gasoline prices, penetration of plug-in electric vehicles (PEV) is bound to increase in the distribution system. The load characteristics of the distribution system with PEVs will be considerably different and hence its effects on the system needs to evaluated. Determination of the characteristics of the impacts will help utilities to prepare methodologies in advance to accommodate this new kind of load. Batteries of most of these vehicles will be charged using a single phase power electronic chargers. To study impact of these chargers on distribution system during fault and fault recovery is the focus of this thesis. The IEEE 13 node test feeder and a single phase Level-2 battery charging system with current controlled and voltage controlled Voltage Source Converter (VSC) is modeled in PSCAD/EMTDC. A car park, with sixteen PEVs, each rated for 6.6 kW, is connected on each of the three phases, at one of the buses in the system. Temporary single line to ground fault (SLG) with auto-reclosure operation is simulated at the bus where the vehicles are connected. The response of the systems in terms of active and reactive power flows, voltage and current magnitudes is evaluated. Based on the observations, the charger is equipped with fault control logic and fault studies are repeated to gage its effectiveness.
