Integrated microgrid protective system using PMU

Abstract

With the penetration of microgrids in power systems, conventional protections have become ineffi cient due to the resulted changes in current characteristics and power fl ow direction. Therefore microgrids have to incorporate smart protection systems. The integrated MG protective system developed in this project is based on phasor measurement unit data measurements of current and voltage. This protection can detect and isolate 3 phase short circuit faults as well as abnormalities such as overload, overvoltage and undervoltage in the different buses of the MG.
