Coordination of directional overcurrent relays using artificial bee colony
22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013This paper proposes to solve the coordination of directional overcurrent relays problem (DOCK) using Artificial Bee Colony optimization (ABC) which is robust and easily implemented. Three case studies were evaluated and implemented on looped 3-bus, 6-bus, and 8-bus systems. The obtained results from the proposed ABC algorithm is compared to those using

Optimized Coordination of Directional Overcurrent Relays Using Genetic Algorithm
2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2018The use of directional current protection is very common in transmission lines and distribution lines with distributed generation, and it plays a key role in ensuring that the power supply is safely and reliably, because improper performance of the protection causes interruptions and generate various disruptions to society.

Optimal coordination of directional overcurrent relays using NSGA-II
Electric Power Systems Research, 2015Abstract This paper presents a new method for coordination of directional overcurrent relays to reduce the discrimination time of the primary and backup relays, by using nondominated sorting genetic algorithm-II (NSGA-II). In order to achieve a reliable protective system, it is necessary to find a solution to avoid having large discrimination times ...

Discrete metaheuristic for coordination of directional overcurrent relays in meshed systems
2013 IEEE PES Conference on Innovative Smart Grid Technologies (ISGT Latin America), 2013This work proposes the use of a metaheuristic method for coordination of directional overcurrent relays in power systems. The proposed metaheuristic is the Discrete Particle Swarm Optimization. The coordination problem is modeled as a mixed integer nonlinear problem due to the available discrete settings in the relays.

A Novel Convexified Linear Program for Coordination of Directional Overcurrent Relays
IEEE Transactions on Power Delivery, 2019A novel convexified linear program for optimal directional overcurrent relay (DOCR) coordination problem (CP) is proposed in this letter. The DOCR CP is a highly constrained nonlinear nonconvex problem which was solved using various traditional and heuristic optimization techniques in the past.

An application of rule based system to the coordination of directional overcurrent relays
6th International Conference on Developments in Power Systems Protection, 1997In this paper, we apply a rule based system, in which production rules are utilized to solve a domain problem, to the relay settings and its time delay coordination for directional overcurrent relays. In order to proceed them efficiently, we first propose a simple algorithm for finding the order of relay settings by using heuristic rules which are ...
