In addition, as renewable energy increases, ESS (Energy Storage System) is gradually being applied to power distribution and transmission and substation. In the future, large-capacity (MW-class) power storage systems are expected to be expanded to substation units.

In addition, new renewable energy generation is expected to increase as the Smart Grid is expanded and applied globally, and with this, power storage systems will be extended to the entire power system, thus integrating multiple power storage systems. It is necessary to develop a technology for a system that can be operated as a system.
