LITHIUM-ION BATTERY TECHNOLOGIES SUITABLE FOR GRID-SUPPORT ENERGY STORAGE SYSTEMS

抄録

A large-scale battery energy storage system for the Nishi-Sendai Substation located in the western part of Sendai City in Miyagi Prefecture, commenced operation in February 2015. The demonstration project has been launched as a new approach to frequency changes caused by weather-dependent power fluctuations resulting from the increasing use of renewable energy sources such as wind and photovoltaic systems. It is expected to contribute to the stabilization of electricity generation and the further expansion of renewable energy sources.
