The main challenge for DC distribution system is the lack of a good protection system. In this paper a ring type DC microgrid is considered. Upon fault in the grid, the existing system shut down the entire grid. A new protection algorithm is proposed which isolates only the faulted section, without the entire grid shut down. The algorithm senses the fault using differential current and then current derivative is taken for segment isolation. The proposed algorithm is verified using Simulink/MATLAB.
