    High pressure grade Federal Reserve energy converter

    The topology of the high voltage cascaded energy storage system consists of grid-connected reactor, cascaded power unit, battery module, and corresponding control and protection equipment. Generation-side energy storage: load regulation, smoothing intermittent energy, increasing consumption of new energy, increasing reserve capacity of power grid, participating in peak regulation and frequency modulation. Transmission and distribution energy storage: improve power quality, reduce line loss, improve the reserve capacity of the grid, improve the utilization efficiency of transmission and distribution equipment, and delay the demand for capacity increase. User-side energy storage: smooth load curve, load transfer, peak clipping and valley filling. Emergency power supply system: it is in standby state when the power grid is normal, and it can be started when the power grid is faulty to guarantee the continuous power supply of the load. Fire power supply, emergency lighting, energy feedback, etc.
