An optimized energy management system for vehicle to vehicle power transfer using micro grid charging station integrated Gridable Electric Vehicles

Abstract

World nations are promoting Gridable Electric Vehicles (GEVs’) in the context of increasing environmental pollution. GEVs’ include Plug-in Hybrid Electric vehicles (PHEVs’) and Battery Electric vehicles (EVs). The increased penetration of GEVs’ into the utility grid for charging, can lead to grid instability and regulation issues. The charging scenarios would be un-coordinated in countries like India, resulting in unstable load demand on the grid. The solution to this is the adoption of an aggregator regulated Micro Grid charging station (MGCS). The MGCS would facilitate energy flow to acceptor GEV clients from donor GEV clients through Vehicle to Vehicle (V2V) power transfer, thereby reducing the load on the utility grid. The MGCS would be supported by a photovoltaic system. This paper proposes the utilization of GEVs’ in supporting the MGCS through the regulation of an on-board Intelligent Energy Management System (IEMS). The IEMS performs communication and price negotiation with the MGCS aggregator; decides the energy level that the donor GEV clients can provide considering its future journey and criticality; and regulate the on board converter to facilitate slow, regular and fast charging of the acceptor GEV clients.
