Scope of Application

Grid-connected and off-grid micro-grid，Micro-grid training platform

Advantages

It takes less than 10ms to switch between grid-connected and off-grid modes, and it has active and passive grid-connected and off-grid switching functions.

When the energy storage coordinating controller detects abnormal voltage on grid side, it will control SCR to cut off, and at the same time, PCS provides voltage support to the micro-grid, and the system operates under island mode;

When the energy storage coordinating controller detects that the grid voltage recovers to normal state, the micro-grid system will synchronize with the grid voltage, and connects SCR to the grid to realize grid-connected operation.

When the energy storage coordinating controller receives the island operation command, the energy storage coordinating controller controls SCR to cut off, and in the meantime, PCS provides voltage support to micro-grid, and the system operates under island mode.

When the energy storage coordinating controller receives the command to exit island operation, the micro-grid system will synchronize with the grid voltage, and connects SCR to the grid to realize grid-connected operation.

Passive switch between grid-connected and off-grid modes

Active switch between grid-connected and off-grid modes
