The rising popularity of EVs leads to a huge count of charging stations which have a significant impact on the electricity grid. In order to minimize the detrimental effects of EV charging and to increase the efficiency of EV grid integration, different operational techniques for grid integration must be established.

In a dynamic tariff environment smart charging and incorporation of compensation devices is an effective solution to improve the overall system efficiency. In the proposed work the reasons for the increased cost of lost power is explored and a suitable method is suggested to minimize the power loss and improve the voltage profile in the presence of PEVs. The proposed methodology deals with incorporation of shunt compensating devices like the DSTATCOM and also tries to establish a suitable charging profile for the PEVs so that the vehicle is fully charged before its departure. The suggested methodology is a combination of the rule based approach proposed for charging of electric vehicles and heuristic approach implemented for the placement of compensation devices. The combined usage of rule based and heuristic approach for charging the vehicles and for the placement of active shunt devices in distribution networks is probably the first attempt.
