The Reactive Power Control block is responsible for regulating the flow of reactive power through the Point of Common Coupling (PCC), when the microgrid is connected to an external AC-grid, by allowing the user to adjust the reactive power settings and maintain stability.

Mask and Parameters

The Reactive Power Controller block contains the following configuration mask:
