Abstract
In this paper, we conducted quantitative analysis of the power supply system in Japan on the premise of massive introduction of variable renewable energy (VRE) for 2050. In the analysis, electricity supply simulation model, of which objective function is minimization of social cost, that can consider ensuring demand and supply balance and control reserve and restriction of inter-connection line capacity was used. As a result, in order to make effective use of the amount of electricity generated by renewable energy, it is important to adjust its placement to demand. Hydrogen production plant and methanation plant should be considered under mass VRE introduction.
