Product description

1. Energy storage at the power generation side: load regulation, smoothing intermittent energy, improving new energy consumption, increasing the reserve capacity of the power grid, participating in peak shaving and frequency modulation.
2. Transmission and distribution energy storage: improve power quality, reduce line loss, improve the reserve capacity of power grid, improve the utilization efficiency of transmission and distribution equipment, and delay the demand for capacity increase.
3. User side energy storage: smooth load curve, load transfer, peak shaving and valley filling.
4. Emergency power supply system: it is in standby state when the power grid is normal, and it can be started when the power grid fails to ensure the continuous power supply of the load.
5. Fire power supply, emergency lighting, energy feedback, etc.
