Modular Energy Storage Converter

Energy storage system is composed of energy storage battery, energy storage converter and distribution system. Energy storage converter is a bidirectional converter, which can store the energy of power grid into batteries or invert the energy of batteries into power grid.
The energy storage system can play a role in all aspects of power system.
- it can provide energy reserve at the generation side, increase the grid-connected rate of clean energy, and suppress the fluctuation of new energy power generation grid-connection.
- in the transmission and distribution link, it can play the role of peak shaving and valley filling in the substation.
- in the user side, the energy at valley value can be stored and used at peak value, which can reduce the cost of electricity consumption.
It has been widely applied in electrical power system.
