This paper presents a new approach for optimal simultaneous coordinated tuning of overcurrent relay for a power delivery system (PDS) including distribution generations (DGs). In the suggested scheme, instead of changing in protection system structure or using new elements, solving of relay coordination problem is done with revising of relays setting in presence of DGs. For this, the relay coordination problem is formulated as the optimization problem by considering two strategies: minimizing the relays operation time and minimizing the number of changes in relays setting. Also, an efficient hybrid algorithm based on Artificial Bee Colony (ABC) and linear programming (LP) is introduced for solving complex and non-convex optimization problem. To evaluate the efficiency and ability of the proposed method, a 30-bus IEEE test system is considered for simulation studies. Also, three scenarios are examined to evaluate the effectiveness of the proposed approach to solve the directional overcurrent relay coordination problem for a PDS with DGs. Simulation result show the efficiency of proposed method. [Mostafa Azimi Dehaghani, Mehdi Soltani, Sayed Mohsen Ahmadi, Payam Ghaebi Panah.
