要約(日本語): In recent years, interest in global warming is increasing. In relation to this problem, in terms of greenhouse gas reduction, expectation for renewable energy is growing. Especially, it is expected that photovoltaic generation will be introduced in large quantities in the future because of its easy installation. However, it is said that the large penetration of photovoltaic generation cause some problems to voltage stability, because its output is unstable and it is connected at the end of the system. In this paper, voltage stability of power system with PV large penetration is studied and the effect of difference of load’s characteristics and voltage control by a transformer tap changer and reactive power control by PCS of PV are discussed.
