Abstract
This paper describes development of a unit commitment model with demand response and electric storage device for the integration of variable renewable energies by considering forecast outputs and errors for photovoltaic and wind power generations. We analyze operation plans for power systems in Tokyo area and Tohoku area where a large amount of variable renewable energies are introduced in 2030. We estimate curtailment of wind power for Tohoku area in 2030 because the power system in Tohoku area can not integrate wind power generation planned to be installed in 2030. Then this paper shows that the integrated operation of the two power systems can integrate both photovoltaic and wind power generations planned to be installed in 2030. Finally we evaluate economic efficiency for the integrated operation of the two power systems.
