Özet
Coordination of Directional Over Current Relays (DOCR) is an important issue in the protection of power sys-tems. In this paper, the object function of DOCR has been modified for better coordination. Manta Ray Foraging Optimization (MRFO) algorithm is adapted to the DOCR with the modified object function to maintain optimum relay coordination by preserving the relay coordination margin between the relay pairs. In order to show the success of the proposed technique, the algorithm has been applied to the 9-bus and 15-bus test system. The obtained results have been compared to other algorithms in the literature. Further, an adaptive protection structure, which provides optimum coordination of DOCR with MRFO algorithm according to changing power system conditions, has been proposed for a network that include Distributed Generation (DG) power plant. The proposed adaptive protection structure has been applied to the virtual model of a cross-section of 10 bus dis-tribution networks that includes a Wind Powered DG (WP-DG) in the Hatay province of Turkey.
