The Active Power Control block is responsible for regulating the flow of active 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 active power settings and maintain stability.
Mask and Parameters
The Active Power Controller block contains the following configuration mask:
