摘要：The Directional Overcurrent Relays (DOCRs) coordination problem is of paramount
importance for power system protection. This paper uses a new metaheuristic method
called the Backtracking Search Algorithm (BSA) to solve the DOCRs coordination
problem. The coordination problem has been formulated as an optimization problem
to minimize the operating time of all the primary relays. The proposed algorithm has
been implemented and applied to three test systems including the 6-bus, the 8-bus and
the 15-bus test systems. Furthermore, a reliable approach has been developed to
compare the results obtained using the proposed BSA with those obtained using other
well-known metaheuristics. The results show the superiority of BSA over other
methods in solving DOCRs coordination problems.
