Overview of battery energy storage systems for stabilization of renewable energy in Japan

摘要

Natural energy generators such as wind turbines and photovoltaics cause instability of the power grid due to their output fluctuations. Battery energy storage systems are being considered as a countermeasure for this issue. This paper gives an overview of battery energy storage systems used for stabilizing the output fluctuations of natural energy generators in Japan. Some verification test results are also shown.
