Peak shaving and valley filling: Store electricity during off-peak hours when prices are low and discharge during peak demand periods to save on electricity costs.
Uninterrupted Power Supply: When the grid fails, the system can seamlessly switch to off-grid power supply, ensuring normal operation of the load.
Dynamic Capacity Expansion: Compensates for short-term power resource shortages and delays distribution investment.
Power Quality Management: Compensates for transient voltage drops in the grid, power factor of the load, and harmonic currents.
Can form a hybrid microgrid system.
