A robust control strategy for a grid-connected multi-bus microgrid under unbalanced load conditions
We propose a control strategy for microgrids under unbalanced load conditions. The proposed controller comprises a PS power controller and a NS current controller. A sliding mode based power controller regulates the generated PS power by DG unit. A Lyapunov function based current controller compensates the NS current of loads. The proposed method is robust and stable under disturbances and uncertainties.
