A Unified Control Strategy for Three Phase Inverter in Distributed Generation

A Unified Control Strategy for Three-Phase Inverter in Distributed Generation: Abstract—This paper presents a unified control strategy that enables both islanded and grid-tied operations of three-phase inverter in distributed generation, with no need for switching between two corresponding controllers or critical islanding detection. The proposed control strategy composes of an inner inductor current loop, and a novel voltage loop in the synchronous reference frame. The inverter is regulated as a current so
