Abstract
In an electric power system with a distributed power source, a fluctuation of its system voltage is brought about by an amount of power generation of the distributed power source that depends on weather. Stabilization of the system voltage is realized by generating a driving signal of a switch that the system has from weather forecast information and power system information and switching a configuration of the system.
