Medium voltage power guarantee solution for mining areas

This solution directly integrates the energy storage system into the medium-voltage line. In the event of a power grid anomaly, the grid-side load is disconnected using a fast switching device, and the energy storage system quickly switches to an off-grid state to provide uninterrupted power supply to the load. Once the power grid is restored to normal, the system switches back to grid-connected mode for energy storage, thereby solving the unified power protection issue for such scenarios.
