要約(英語): According to rapid increase of photovoltaic (PV) and wind generations in recent power system of Japan, the cases arise that power generation exceeds demand, so PV generations must be curtailed in some area. Hereafter, part of PV and wind generations may be curtailed in other areas too. In Europe and America too, similar surplus electricity are genetated and capacity of battery to withdraw surplus electricity are researched. This paper analyzes basic supplying characteristics of PV and wind generations in the simplified model system based on the actual power system in north-east area in Japan. As a result, when penetration ratio of PV or wind generation exceed 10~20%, surplus energy arise. It needs much capacity of battery to withdraw surplus energy, so supplying cost including battery is several ten times of cost of generation alone. If minimum output of stable generations except PV and wind generations could be lowered, surplus energy, capacity of battery and supplying cost will lower remarkably. But unit supplying cost of stable generations increases. According to introduction of much PV and wind generations, more coordination of power system and PV, wind generations is necessary, i.e. scaling up and cost down of energy storage, extension of power control range of stable generations, demand side management, etc.
