“…Linear programming approach based on interval analysis concept was also used for solving the directional over current relays (DOCRs) coordination problems. These techniques also considers the effect of network uncertainty in defining the relay coordination problem [32,33]. In [34][35][36], linear programming methods were discussed in which constraints relaxation was also considered for optimal coordination of over current relays for interconnected power networks.…”

“…In [28], the fitness function is also defined minimization of operating time of primary relay as well as backup relays. However, few researcher proposed the fitness function as minimisation of time dial setting [33] of primary relays. In all above fitness function formulation techniques, it is observed that, relay coordination problem becomes highly nonlinear and non-convex optimization problem.…”

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.

“…Thus, conventional protection schemes that are designed for power systems without considerations of the DG impacts are insufficient for supporting wider renewable energy-based DG penetration [23][24][25][26][27][28]. Thus, a new generation of protection schemes that explicitly considers these requirements and adapts the system operation are strongly required [29][30][31][32].…”

Adaptive Protection Scheme for a Distribution System Considering Grid-Connected and Islanded Modes of Operation

et al. 2016

View full text Add to dashboard Cite

The renewable energy-based distributed generation (DG) implementation in power systems has been an active research area during the last few decades due to several environmental, economic and political factors. Although the integration of DG offers many advantages, several concerns, including protection schemes in systems with the possibility of bi-directional power flow, are raised. Thus, new protection schemes are strongly required in power systems with a significant presence of DG. In this study, an adaptive protection strategy for a distribution system with DG integration is proposed. The proposed strategy considers both grid-connected and islanded operating modes, while the adaptive operation of the protection is dynamically realized considering the availability of DG power production (related to faults or meteorological conditions) in each time step. Besides, the modular structure and fast response of the proposed strategy is validated via simulations conducted on the IEEE 13-node test system.

ÖZETBu çalışmada 154 kV transformatör merkezlerinde, güç transformatörü giriş ve çıkış fiderleriyle orta gerilim dağıtım fiderlerinin optimum ters zamanlı aşırı akım röle koordinasyonu, ceza fonksiyonuyla durdurmalı Genetik Algoritmalar (CFD-GA) yöntemiyle yapılmıştır. Yeni bir yöntem olan CFD-GA yönteminin, aşırı akım röle koordinasyonundaki performansına vurgu yapılmıştır. Bu yöntem, selektivite bölgeleri arasındaki zaman farkı esnekliğiyle her çeşit aşırı akım röle koordinasyonu yapabilen bir yöntemdir. CFD-GA ile hem geleneksel ani ayar mecburiyetli hem de ani ayarsız aşırı akım röle koordinasyonu uygulamaları yapılmıştır. Ayrıca, çaprazlama ve mutasyonda yalnız 2 tabanı, yalnız 10 tabanı ve her generasyonda rasgele olarak belirlenen 2 ya da 10 tabanından birini kullanan karışık tabanlı CFD-GA, röle koordinasyonu uygulamalarında karşılaştırılarak, taban performansı belirlenmiştir.Anahtar Kelimeler: Transformatör Merkezi, Koruma, Aşırı Akım, Anisiz Koordinasyon, Genetik Algoritma. OPTIMUM OVERCURRENT RELAY COORDINATION VIA GENETIC ALGORITHM METHOD STOPPED BY PENALTY FUNCTION IN SUBSTATIONS ABSTRACTIn this study, in 154 kV substations, optimum inverse time overcurrent relay coordination of power transformer input and output feeders and of distribution feeders are formed. A new GA method stopped by penalty function (CFD-GA) is utilized at the design stage. The performance of the method is emphasized. This method is able to do all kind of overcurrent relay coordination owing to time difference flexibility between selectivity zones. Overcurrent relay coordinations with both compulsory instant setting and without instant setting are made via CFD-GA. Three kinds of applications are made; Only 2 base, Only 10 base, randomly chosen 2 or 10 base are used in crossover and mutation in each generation. The results of these applications are compared with each other and the base performance is determined.
