Description
Problem may occur in the coordination among different protective equipment on grid side or on microgrid side. When fault occurs in a conventional power system, it is fed from generating side and feeding of fault current is said to be unidirectional. But, in case of utilities being integrated with microgrids, another situation comes forth where fault is fed from both sides in the form of flow of bidirectional currents that makes the faulty conditions more complex.
