The massive deployment of PV and wind, which provides decarbonized energy supply, bring about various additional challenges in operation of a power system. The congestion of transmission lines is an emerging issue which has been constraining new connections of renewable generation such as photovoltaic and wind. Recently, the rules to connect and operate generation have updated to accept new connection which occur congestion of transmission lines with the condition that the new-connected generation accept output control in case transmission congestions occur. Under this situation, production cost simulation including transmission constraints is a mandatory for planning and operation of a power system and for evaluation of each renewable energy project. In this study, the authors modeled demand and supply condition and transmission and simulated power flows of transmission lines in the Hokkaido in FY2019 to verify them against historical data.
