Nonlinear Output Feedback Droop Control for Parallel Inverters in Standalone Microgrids

摘要: This paper proposes a nonlinear control scheme for power-sharing between parallel distributed generations in standalone microgrids. Generally, linear control-based droop method is applied to balance the power multigenerating units and demands; however, poor performance of such types schemes observed under sudden change operating point. To overcome this issue, designs output feedback linearized active reactive sharing network. The proposed controller demonstrated load variation using simulations Simulink AC microgrids system.
