Modified Cuckoo Search Algorithm for Fittest Relay Identification in Microgrid

摘要

Microgrid is a group of interconnected generating units and loads at the distribution level which operates in two modes-Grid connected mode and Islanded mode. Fault clearance in a microgrid is a key challenge for protection engineers. This paper aims to identify the best fit relay suitable for a microgrid using modified cuckoo search algorithm based on key parameters like current rating, Time Multiplier Setting (TMS), Plug Setting Multiplier (PSM) and time of operation (t_(op)). This algorithm aids in providing suitable relay coordination in microgrid and clears the faulty portion of network effectively from the healthy portion of network.
