An approach of distribution systems stabilization for a large-scale PV systems installation environment

Japan has been promoting the plan of renewable energy sources expansion and residential PV installation is one of main targets to promote. Therefore the instability of PV and a voltage rise in distribution systems due to reverse power flow by PV are important issues to solve. This paper proposes a new type of distribution system stabilization method utilizing huge data from smart meters which are expected to penetrate. In order to realize the measure, a new approach of distribution systems management is also proposed.
