Abstract
Analysis of a microgrid via small-signal stability method is well established. However it only depicts the system dynamics around the equilibrium point. To fully investigate the behavior of a microgrid, the phase-plane method should be adopted. In the paper, the state space model of a simplified microgrid under PQ control mode is established. The phase diagrams under three types of load are studied respectively with the help of PSCAD/EMTDC. Some ways to stabilize the system are proposed at last.
