Abstract

Intentional islanding of distributed generation systems requires seamless transition of power between grid connected and islanding modes, ensuring little or no disruption to the local loads. This paper conducts a detail study regarding the factors affecting seamless transition. A control scheme for grid connected and islanding mode of operation with a passive islanding detection algorithm, synchronization algorithm and recloser algorithm is developed. Simulation studies are carried out to evaluate the performance of the controller in grid connected and islanding modes and the possibility of seamless transition between both modes is verified.
