Abstract

A method is presented to model and tune microgrid-connected solar photovoltaic sources (MCPVs). The proposed controller combines maximum power point tracking with droop controller to participate in voltage and frequency regulations of islanded microgrids. In this paper, the controllers required by the MCPV are developed and a modeling procedure is presented to tune the controllers. The effect of MCPV penetration level on the controllers design is reflected in the model and a method is proposed to stabilize the MCPV as it switches among operation modes. The effectiveness of the proposed method is verified by simulation and experimental studies.
