In the energy storage system, the energy storage converter is a device connected between the battery system and the power grid (and/or load) to realize bi-directional conversion of electricity, which can control the charge/ discharge process of the energy storage battery, convert AC and DC, and supply power directly to the AC load in the absence of the power grid.
It can be applied to the power generation, transmission and distribution side and user side of the power storage system. It is mainly applied in renewable energy stations such as wind, solar power stations, transmission and distribution stations, industrial and commercial energy storage, distributed micro-grid energy storage, PV-based electric vehicle charging stations, etc.
