| Abstract | A problem of excess voltage will arise frequently as distributed generation, particularly photovoltaic and wind power generation, increases in society. One of the effective measures to cope with this problem is to supply an appropriate amount of reactive power from generators. In doing so, an appropriate cost sharing rule needs to be established. To this end, it is important to determine what amount of negative effect a unit of real power output by a distributed generator has on the voltage stability. The purpose of the study is to propose a method for measuring this effect. The proposed method is an application of the Aumann-Shapley rule, which is one of cost sharing rules among multiple goods. The method computes an amount of reactive power required for a unit of real power output by a distributed generator, which enables a system operator not only to cover the total amount of reactive power needed but also to fairly estimate the negative effect of real power output. The method may be useful for designing a different kind of feed-in tariff system that embodies the negative effect of distributed generation on an electric power system. |
