Abstract-- The anticipating large penetrations of PHEVs in the smart grid environments brings up many technical issues (V2G, G2V, energy management, etc.) that need to be addressed. An emerging issue is that a large amount of PHEVs simultaneously plug-in to the grid (e.g. at a municipal parking deck during a ball game) will have a huge potential to threaten the power system power quality and stability. In this paper, the effect of hybrid demand side management and demand response programs will be well presented. Case studies show how the price factor could be fully considered into an intelligent energy management system (iEMS) for PHEVs. Accordingly, the simulation results show the optimal electricity consumption by PHEVs considering both local load policy (e.g. critical load) and demand response.
