要約(英語): The installed capacity of photovoltaic (PV) systems has been increasing rapidly due to the enforcement of the feed-in tariff scheme in Japan. However, reverse power flows from the roof-mounted PV systems cause voltage-rises in distribution networks. PV output can be separated into two fluctuation components, short-period and long-period. Long-period fluctuation is compensated by SVR (Step Voltage Regulator) with low response speed, and short-period fluctuation is stabilized by reactive power compensation with high response speed. As for the reactive power compensation, installing SVC (Static Var Compensator) in high-voltage lines has been studied. On the other hand, the idea of installing reactive power compensators in low-voltage lines has been proposed as a promising alternative. This paper proposes a method for analyzing the cost-effectiveness of the reactive power compensators, considering SVR and the constant power factor control of PCS (Power Conditioning System). The proposed method calculates the break-even cost of pole-mounted equipment to SVC, and analyzes the changes in the break-even cost under various power system conditions.
