Active Power Dispatch


 

image-20240916-091713.png

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. This block is part of the microgrid library from the OP1420, and should be used along with the other blocks.
