Grid Stabilization by Use of an Energy Storage System for a Large-Scale PV Generation Plant

摘要

A new energy storage system for a large-scale PV generation plant is reported in this paper. The system is applied to the demonstrative research project of New Energy and Industrial Technology Development Organization (NEDO). Leading-edge control technologies of NAS battery system contributing to grid stabilization and the power station output management system are described. Moreover, some valuable results of demonstrative tests are shown. Through the tests, it is proved that it is able to control PV output and it is possible to operate as a power station.
