Innovative detection of isolation and recombination technique with micro grid

Abstract

An innovative technique of the Unified power quality conditioner for the location, control and integration in the Distributed generation which is based on autonomous and grid connected µg system is proposed and simulated. At Point of Common Coupling, DG converters that has storage andshunt part of APFof UPQC are connected. Before the PCC, the grid and the series part of the UPQC APFare connected in series. Also the DC link is integrated with energy storage. As a secondary mode of control, an innovative technique is introduced in UPQC for the detection of isolation and recombination inµg. Henceforth, it is described as innovative detection of isolation and recombination technique. In this system an effectual method is used for proper functioning of the recombination and isolation detection. Along with the increase in the quality of the power in terms of voltage sag/swell, compensation of the reactive power and harmonics in recombination mode, additionally it compensates voltage interruption over normal UPQC and also DG converter remains connected during the conditions of disturbances in voltage and also phase jump. The performance of the UPQC is simulated and results are analysed.
