Abstract
The concept of microgrid is implemented on a large scale in the present distribution system. Reconfiguration in microgrid predominantly occurs due to connection and disconnection of the distributed generators (DG) and loads. Due to frequent topology changes, conventional protection schemes may not be applicable in microgrid for efficient fault clearance. This paper proposes a Hybrid Borůvkas - Johnsons’s algorithm which detects the shortest path between the fault and the point of common coupling. This ensures that minimum portion of network disconnection occurs during fault clearance. This algorithm is tested and validated on 30-bus standard microgrid network
