“…In [102,103], new protection coordination model, based on agent technology is discussed for protection coordination application for a DER connected distribution system. In [104], pair-to-pair agent based simulated communication for relay coordination has been developed. Another technique based on multi-agent which divides the network into different zones is discussed in [105].…”

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.

La protección adaptiva ha sido estudiada en [13][14][15][16] y la coordinación en línea ha sido propuesta también en [17] para mejorar el desempeño de los relevadores en cuanto a tiempo de operación, sensitividad y habilidad para tolerar contingencias. Para fines de minimizar aún mas el tiempo de operación de los relevadores, coordinación mediante curvas no convencionales fue reportadas [18][19].…”

The coordination of directional overcurrent relays (DOCRs) has been formulated with different optimization algorithms (deterministic, heuristic, swarm, and evolutionary). The surge of studying coordination problem using heuristic, swarm and evolutionary optimization methods became popular. Because the coordination optimization problem is highly complex and nonlinear, some algorithms may result in undesired operation time of DOCRs and also violation of coordination constraints. Therefore, the primary objective is to focus on the use of Trigonometric Differential Evolution (Tri-DE) algorithm in solving complex and nonlinear DOCR coordination. The secondary objective is to improve the Trigonometric Differential Evolution algorithm in the coordination problem and compare it with the original Tri-DE algorithm.

“…In these relays, if the incoming current is higher than the preset current value, the relay will send out an output signal to the circuit breaker (CB) to disconnect the circuit in order to protect the power components from the result of current excess [6]. There are three main types of OCRs used in power systems, which are: definite current relay, definite time relay and inverse time relay [7]. The most common type is inverse time relay which has an inverse curve characteristic.…”

Wind power plants are one of the most crucial types of renewable energies which are increasingly employed in smart grids with purpose of power generation especially as a distribution generation system. Hence, the proper protection of wind plants is an enormously significant aspect which must be taken into consideration when designing the wind plants to not only provide a suitable protection for the power components but also maintain the power generation perpetually in case of fault. The most important and common protection systems are overcurrent relays which can protect the power systems from impending faults. In order to implement a successful and proper protection for wind power plants, these relays must be set accurately and well coordinated with each other to clear the fault at the system in the shortest possible time. This paper demonstrates how the coordination of overcurrent relays can be successfully achieved in wind power plants in order to maintain the power generation during fault and protect the power components.
