Abstract :
Vehicle to grid system (V2G) provides frequency regulation for electricity networks. Network operators receive benefits from V2G for more stable network and price difference when selling and buying electricity in networked markets. In this proposal, we estimate the annual cost for battery wear due to V2G application to be AU$ 770. Grid operators use 102 kWh per day battery capacity to exchange electricity between car batteries and electricity networks. The energy price used for frequency regulation is in this research project 2.07 AU cents per kWh. Intensive power exchange, between batteries and electricity network can cause extra wear for batteries, which is increasing cost. The model used in these calculations were based on Sanyo UR18650E Electric vehicle (EV) batteries at a size of 85 kWh battery package. Results demonstrate that V2G will provide inexpensive frequency regulation for power grid and generate profit for electricity network operators and electric car users.
