要約(日本語): Because of the important issues such as the resource shortage and the global warming, the attention to photovoltaic generation has recently been increased, and a lot of photovoltaic generations will be installed to the power system in the future. This will largely affect the power flow in the system, and consequently the voltage profile and the voltage characteristic. From these reasons, it is expected that the penetration of photovoltaic generation have some impact on the voltage stability in the power system. In this paper, the transmission characteristic (PV curve) of a power system which consists of one load, one photovoltaic generation, and infinite bus is considered, and the features of the PV curve of the power system with photovoltaic generation are studied. From the features, the voltage stability in the power system with a large penetration of photovoltaic generations is discussed.
