“…Main protection and backup protection are two kinds of protection incorporated in the power system [16].OC relay gives protection against short circuits and also helps in protecting apparatus from damage. OC relays as primary protection needs to be coordinated with adjacent relay used in backup protection.…”

Overcurrent(OC) relay is one of the most commonly used protective relays in the power system. Coordination of overcurrent relays is a challenging task in the field of offshore wind farm (OWF). A reliable protection system is needed for transmitting large amount of power over long distances. An optimal relay coordination using overcurrent relay is used at four different points in the OWF. The optimal coordination of OC relay is carried out by the exploration of different meta heuristic algorithm such as Genetic algorithm (GA), Particle swarm optimization (PSO) and Gravitational search algorithm (GSA) algorithm. The formulation of objective function is accomplished by two variables such as time multiplier setting (TMS) and plug setting multiplier (PSM).Thus this multiobjective optimization is explored to minimize the operating time of the associated relay that exists in the ac side of OWF.

“…For this purpose, Genetic Algorithm (GA) was applied to the coordination problem to achieve the global optimum value with less computational time [20]. By taking the advantage of GA in a way of generating multiple initial relay setting instead of a single set, Hybrid-GA, GA with Non-Linear Programming (GA-NLP) and Continuous Genetic Algorithm (CGA) have been proposed to solve the coordination problem [21][22][23]. GA has lack of ability to keep the good solutions although it proposes appropriate solutions to solve the coordination problem.…”

On-Line overcurrent relays setting approach in distribution networks by implementing new adaptive protection algorithmAbstract-In order to meet the ever increasing demand for power, the government has revised its targets in increasing power generation. For this purpose, installation of new equipment or utilization of Distributed Generation (DG) has been employed. In addition to changes in topology of power grid, the amplitude of the short circuit currents also can be affected due to these developments. In this condition, fixed setting for the protective relays cannot respond correctly. In order to prevent any miscoordination or mal-operation, relays have to be adaptively coordinated for a new system configuration to achieve correct fault clearance operation. In this paper, a reliable protection scheme is achieved by implementing the proposed adaptive protection algorithm. As results show, proposed new settings for the relays avoid the risk of unnecessary blackout for distribution network consumers. In addition, sensitive and reliable protection scheme is achieved by implementing the proposed adaptive algorithm.1 978-1-4799-8055-0/15/$31.00 ©2015 IEEE

Emission of greenhouse gases and depletion of fossil fuel reserves are two key drivers, which are forcing the mankind to generate the future energy demand from the renewable energy resources. These resources are generally distributed in nature and are directly integrated at distribution levels. Increasing penetration of the distributed energy resources in distribution power networks creates additional operational and control issues. These are mostly regulatory, economical load dispatching, power quality and protection issues. Generally power distribution systems are protected with the help of dedicated over current based protection schemes. But increasing share of distributed energy resources penetration in electric utilities poses a serious threat to the existing protection coordination schemes of the distribution systems. Distributed energy resources connected distribution networks become interconnected in nature and protection coordination schemes, which are designed for unidirectional flow of fault currents become ineffective/non-functional. Therefore, new protection coordination schemes are required for providing the adequate protection coordination for distributed energy resources connected electric power networks. In the available literature, the protection coordination schemes for radial distribution systems and developments in the area of protection coordination are discussed in detail. A thorough review for all these protection coordination schemes for distribution systems with and without distributed energy resources is done in this review article. It includes the analytical and artificial intelligence based techniques application for coordination of protective relays in the distribution systems. The limitations and research gaps in the area of protection coordination schemes are also presented in this review article. The aim of this research paper is to bring all the available research in the area of relay coordination on one platform, so that it will help the emerging researcher to identify the future scope of relay coordination application for distributed energy resources connected distribution systems.
