Since the power output of variable renewable energies (VREs) depends on weather conditions, it is difficult to supply electricity according to demand. The introduction of a large amount of VREs will result in excess power plant capacity to meet electricity demand, increasing costs associated with power generation and power plant capacity, etc. Therefore, it is important to reduce wasted electricity. One effective way to use surplus electricity is to utilize it for automobile traffic. In this study, we analyzed the optimal power supply configuration and cost reduction effects by utilizing surplus power from the massive introduction of VREs for electric vehicles (EVs) and hydrogen production power for fuel cell vehicles (FCVs). Adding the demand for hydrogen from FCVs as well as EVs demand can reduce the overall cost of the system by effectively utilizing the surplus electricity from the increased share of VREs after 50%. Optimizing EVs recharging and hydrogen filling leads to reductions in power plant capacity and storage battery installation, effective use of the facilities in each region, and contributing to the reduction of excess electricity.
