Study of Impact on Supply and Demand Operation by the Amount of V2G Controlled Electric Vehicles Installed

抄録

This study simulates supply-demand operation based on Electric Vehicle (EV) travel data and examined the impact of the amount of V2G controlled EVs installed on supply-demand operation. We evaluated the effect of reducing supply and demand adjustment costs by converting all buses, trucks, and passenger cars in the Kanto region to EVs and not converting to EVs, with a renewable energy (RE) ratio of 0-50%. In all cases, even taking EVs operation into consideration, the installation of V2G controlled EVs were confirmed to reduce the demand and supply adjustment cost. In addition, it is observed that fuel costs can be minimized by utilizing the adjustment capability of EV batteries to perform the respective functions of supply, surplus, and balancing in response to the ratio of demand and RE. The study also highlights the significant reductions in social costs achieved through the installation of EVs when considering fuel conversion and the cost of increasing stationary storage batteries.
