Application Scenarios
Generation-side
Enhance the stability, continuity, and controllability of renewable energy generation, thereby providing stability support to the power grid.
Grid-side
Participate in grid dispatching to meet peak-shaving and frequency-regulation requirements, thereby improving the flexibility and stability of the power system.
User
Alleviate grid load, meet diverse electricity demand from end-users, strengthen power-supply reliability on the user side, and improve the overall user experience of electricity consumption.
