basic information
The SDPCS energy storage converter provides an interface between the power grid and the energy storage battery to realize the charging and discharging of the energy storage battery system. The energy storage converter can be used in the grid connected system to realize frequency modulation, peak regulation, active power reserve, reactive power support, energy transfer, and new energy consumption. At the same time, it can also establish voltage source support for off grid black start to provide backup power for the load.
