AN EFFECTIVE ENERGY MANAGEMENT SYSTEM FOR GRID CONNECTED ELECTRIC VEHICLES

The coordination of charging and discharging between plugged electric vehicles and main electrical grid/microgrid is very important to maintain good performance from both vehicle and grid side. As of now several controllers are proposed for energy management between grid/microgrid and electric vehicles. In this paper, presenting an aggregator based controller which is helpful for better energy management in the charging and discharging mode of electric vehicle in coordination with charging technologies. The proposed controller is having the technical capability of load assessment, optimal charging/discharging capability, load shedding, and demand side management. The proposed controller is feasible to solve the charging/discharging issues with EV's and energy management issues with the main grid. This controller also helpful to improve the overall system performance with the help of bidirectional converter and reduce the overloading on the system improves power quality and reduces power loss of the system.
