摘要

This paper presents roles of technologies which manage surplus electricity derived from a massive deployment of variable renewables (VRE) for energy system decarbonization in Japan. A bottom-up energy technology model which covers a whole energy system and incorporates a high-temporal-resolution power sector is developed and utilized. The model is formulated as a large-scale linear programming model with 11 million endogenous variables and 25 million constraints. Simulation results reveals that massive decarbonization results in the occurrence of huge amount of surplus electricity and requires installation of surplus electricity management technologies. Stored batteries, charging of electric vehicles and heat conversion as well as suppression of VRE power output would play substantial roles to manage the surplus electricity. A degree of utilization of electrolyzer depends on its cost and carbon constraints although the installed capacity is limited compared with other management technologies at any case assumed in this study.
