Faster fault detection and location has become one of the prime assignments in microgrids for better control strategies. Quick identification of fault may result in location estimation tougher due to insufficient measurement data. In this article, a better scheme for fault detection and a novel method for the location of fault with good accuracy are portrayed. The speed and cost‐effectiveness of the proposed scheme has been assured due to less sampling frequency. The proposed method is developed for a standalone low voltage DC (LVDC) system with photovoltaics and battery energy storage system. A large number of fault scenarios have been simulated and analyzed by varying faults (pole‐pole, pole‐ground), fault resistance, and locations. The proposed scheme deals with local measurements that heartens the easy implementation of the proposed method. The case studies have been simulated in MATLAB/ SIMULINK environment. The efficacy of the proposed protection scheme is further validated in a real‐time environment.
