Abstract

In recent years, due to the increasing penetration of renewable energy resources, the concept of DC Microgrid is determined. In addition, the lack of effective protection strategy and standards for DC Microgrids jeopardizes the reliability of these systems. In this paper, a protection scheme for interconnected DC Microgrids by using a distribution sensitive poverty index is proposed. This strategy is designed by monitoring of current of interconnected line and sending to a central protection unit to detect and isolate the faulty DC Microgrids. The proposed method is able to detect and isolate DC Microgrids in case of the line to ground and line to line faults in case of low and high impedance faults. The effectiveness of the proposed method is proved by the implementation of an interconnected DC Microgrid in MATLAB. The results show the speed and capability of fault detection in different scenarios.
