Most Valuable Player Algorithm for Solving Direction Overcurrent Relays Coordination Problem

This paper proposes the application of Most Valuable Player Algorithm (MVPA) to find the optimal solution for directional overcurrent relays (DOCRs) coordination problem. The coordination problem of DOCRs is considered as a non-linear optimization problem. The decision variables for this problem are relay settings. Minimize the summation of the operating times of all primary relays with maintaining the coordination margin between relays pairs is the main goal of this study. The feasibility and performance of the proposed algorithm for solving the coordination problem of DOCRs are assessed in two test system (8-bus and IEEE-30 bus). The results show the ability of the proposed algorithm for solving DOCRs coordination problem without any miscoordination. The results of the proposed optimization algorithm are compared with other previously optimization techniques.
