Renewable energy resourses such as photovoltaic (PV) power and wind power have been installed in power networks as one of the countermeasures for global warming and depletion of fossil fuels. In particular, PV is the most promising of all renewable energy sources in Japan. However, the voltage may be risen due to the reverse power flow by connecting them to the distribution network. As one of the solutions for voltage problems due to the large scale penetration of PV generation, Voltage regulation by SVR (Step Voltage Regulator ) has been expected. In this paper, we examine the optimal allocation and planning of the SVR for stabilizing voltages when PV generators are installed to a large extent into distribution networks. As a result, the voltage deviation can be reduced 84.5% on average with introducing a SVR. The optimal allocations are depended on capacities of PV generators. In addition, the voltage deviations are decreased 2.17% on average in every PV installation plan by replacement a SVR.
