This document summarizes a research paper that uses a genetic algorithm to optimize the coordination of overcurrent relays in an electrical power distribution system. The paper formulates the relay coordination problem as an optimization problem to minimize the total operating times of relays while satisfying coordination constraints. A genetic algorithm is applied to find the optimal settings for time multipliers on the relays. As a case study, the algorithm is applied to coordinate relays on a simple radial system and finds settings that achieve the minimum fitness function value while satisfying constraints. The genetic algorithm approach provides an effective method for automating the optimization of relay coordination in electrical power systems.
