Microgrid distance protection

Impedance or distance relays are widely employed to protect transmission networks and have recently been recommended to protect MGs, as they can detect and respond to both forward and backward faults. ∙ Distributed support vector machine-based algorithms for fault detection and localization, featuring. . This example shows how to model a distance relay in an AC microgrid. The relay block comprises impedance relay characteristic and mho relay characteristic. The design of both systems must consider the system topology, what generation and/or storage resources can be connected, and microgrid operational states (including grid-connected, islanded, and transitions between the two). This paper proposes an artificial neural. .
