Balanced islanding detection of integrated DG with phase angle between voltage and current

Abstract

The integration of renewable energy systems is enhancing in daily life for supplying the global demand for electric energy. The concerning problem with the integration of such distributed generation (DG) is islanding. It may damage the consumers and equipment. As per the IEEE 1547 DG integration specifications it must be identified in 2 seconds. In this article a novel passive recognition approach occupying on the rate of change of phase angle between positive sequence voltage and current is (RCPABPSVAC) is proposed. The existing passive methods failed to detect balanced and low power mismatch islanding cases. The suggested approach can do it and strongly classifies the non islanding situations with the islanding situations. The simulations are implemented in MATLAB/Simulink environment.
