The number of plug-in electric vehicles (PEVs) entering into the market is increasing and many of these vehicles are supposed to participate in vehicle-to-grid (V2G) power transactions in the proposed smart grid infrastructure, where bidirectional power flow between the vehicle and the grid will become very obvious. In that scenario, it is quite reasonable to assume that the plug-in vehicle parking lots or the ‘SmartParks’ can be used as energy storage and with a proper coordination with the wind farm, they can minimize the shock on the system during wind speed fluctuations, reduce the congestion in the transmission lines and also improve the stability of the system.
This research investigates the capability of the SmartParks as shock absorber for the wind farm. Also, the reactive power injection capability of the SmartParks is explored which can improve the voltages of the weak buses. Additionally, if that reactive power can be coordinated with the grid side inverter of the wind farm, the fault ride through capability of the wind farm can be improved. It is imperative for maximum benefits of all smart grid components and technology to be realized that wide area monitoring and coordinated control is implemented.
