Fault Analysis of a Distribution System Embedded with Plug-in Electric Vehicles

One of the most promising ways to reduce NOX and SOX emissions due to conventional vehicles is to change our ways by use of plug-in electric vehicles (PEVs). However integration of large scale PEVs to the grid will create new problems especially at distribution network level. The research done on PEV charging impact shows that the secondary voltage is affected more significantly than the primary voltage which can affect the fault location process. Impacts on distribution system due to large scale integration of electric vehicle during fault condition have been studied in this work. To investigate the impacts on fault condition in distribution system due to PEV integration, the IEEE 34 node system with PEV charging station coupled to one of its node is used under single line to ground fault condition.
