Solving Directional Overcurrent Relay Coordination Problem Using Artificial Bees Colony
This paper presents the implementation of Artificial Bees Colony (ABC) algorithm in solving Directional OverCurrent Relays (DOCRs) coordination problem for near-end faults occurring in fixed network topology. The coordination optimization of DOCRs is formulated as linear programming (LP) problem. The objective function is introduced to minimize the operating time of the associated relay which d...
متن کاملModified Swarm Firefly Algorithm Method for Directional Overcurrent Relay Coordination Problem
Computational intelligence method such as Nature Inspired Algorithms (NIA) or meta-heuristic algorithms based optimization methods known to be successful in coordination of directional overcurrent relay. It has also been reported that it outperformed the conventional approach. Due to its advantages, it has gained more popularity among the researchers. Some of the conventional optimization techn...
متن کاملApplication of Artificial Bees Colony Algorithm for Optimal Overcurrent Relay Coordination Problems
This paper presents optimal coordination of overcurrent relays by using artificial bees colony algorithm. The objective function of the relay coordination problem is to minimize the operation time of associated relays in the systems. The control variables used in this paper are the pickup current and time dial setting of relays. The proposed method was tested with four systems study consists 5-...
متن کاملCoordination of Overcurrent Relay in Distributed System for Different Network Configuration
This paper presents a study on protection coordination of overcurrent relays (OCRs) in a distributed system by considering its different operating modes. Two different case studies which are considered in present work for protection coordination include: (i) DG interfaced distribution system in grid connected mode and (ii) DG interfaced distribution system in islanded mode of operation. The pro...
