The modern power system networks are very complex and often consist of multiloop structures with increased penetration of renewable energy sources based distributed generations. directional overcurrent relays (dors) are the key protection devices in such networks and their coordination has a profound impact on the overall protection of networks.

Figure 1 From Optimal Coordination Of Overcurrent Relays In An In , various metaheuristic methods including ga, pso, de, hs and soa have been compared in several ieee power systems for the coordination of directional overcurrent relays. one of the systems reviewed in this paper is the ieee 30 bus system, which is also reviewed in the present research. The challenge related to the coordination of overcurrent relays in a looped network, which is a highly constrained problem, is to find a more optimum solution and at the same time there is no miscoordination. in this problem, the utilized optimization algorithm has a direct effect on finding a more optimal solution. high exploration particle swarm optimization (hepso) algorithm, which utilizes. Maintaining a stable operation of modern power systems, which are heavily loaded and strongly interconnected is a very complex task. this requires an optimal setting and coordination of protective relays considering the transient behavior of power systems. this paper proposes a new formulation of the optimal coordination of directional overcurrent relays (docrs) problem, considering power.

Achieving optimum coordination of directional overcurrent relays is a very complicated task in the large interconnected system including huge numbers of relays. in the literature, various objective functions (ofs) are reported to obtain minimum operating time of relays and minimum prescribed discrimination time between the operations of primary. In power systems protection, the optimal coordination of directional overcurrent relays (docrs) is of paramount importance. the coordination of docrs in a multi loop power system is formulated as an optimization problem. the main objective of this paper is to develop the whale optimization algorithm (woa) for the optimal coordination of docrs and minimize the sum of the operating times of all.
