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:

Name	Unit	Description
Sample time	s	Simulation time step
Active Power Diesel limits	pu	Minimum and maximum values for Diesel generation
Active Power BESS limits	pu	Minimum and maximum values available for energy storage using BESS
State of Charge (SoC) limits	pu	Minimum and maximum values of State of Charge
Inner state of charge (SoC) limits	pu	Minimum and maximum values of Inner State of Charge
