Abstract
A micro-grid control system has a first 2×2 decoupled controller that controls voltage and voltage angle by adjusting real and reactive power using real time feedback, and a second 2×2 decoupled controller that controls real and reactive power by adjusting voltage and voltage angle using real time feedback. The first 2×2 decoupled controller and second 2×2 decoupled controller together form a hierarchical microgrid control system, where the second 2×2 decoupled controller is a supervisory controller of the first 2×2 decoupled controller. The micro-grid control system may also include a third 2×2 decoupled controller that supervises the second 2×2 controller.
