Adaptive directional overcurrent relay coordination using ant colony optimisation
IET Generation, Transmission & Distribution, 2015 The coordination of directional overcurrent relays is most commonly studied based on a fixed network topology within an interconnected power system. Due to its complexity and non‐linearity, the relay coordination is formulated as an optimisation problem.

Optimal coordination of overcurrent relays for microgrid operation using JAYA algorithm
e-Prime: Advances in Electrical Engineering, Electronics and EnergyIn modern microgrids, relay coordination is a very tedious task because of the variation in magnitude and direction of fault current. The change in fault current is diverse for inverter interfaced DGs (IIDGs) and synchronous-based DGs (SBDGs) The ...
