Abstrakt

DC Microgrid protection is one of the challenges in utilizing DC Microgrids. This paper offers a protection scheme for DC Microgrids with ring configuration by using local intelligent electronic devices. This method is based on monitoring the distribution-sensitive poverty index, which is calculated by using the current in different sample times. Moreover, this protection method only uses the local data at the intelligent electronic devices without using any communication links; thus, it increases the reliability and also decreases the cost of the protection system. In addition, the proposed scheme is capable of detecting the high impedance faults within the DC Microgrid lines. The effectiveness of the proposed strategy is demonstrated by using simulations in different scenarios. Simulation results indicate that the proposed method can detect both low and high impedance faults within several milliseconds, and the comparison with other fault detection methods reveals the superiority of the proposed strategy.
