A Comprehensive Analytical Review on Distribution Network Protection Control Strategies in the Presence of Distributed Generation Resources

Today, one of the most important challenges of power network operators and designers is to find a suitable solution to deal with the increasing presence of distributed generations in distribution networks for abnormal operating conditions such as fault conditions. The existence of environmental and economic advantages of distributed generations has led to the expansion of the use of distributed resources, especially renewable resources, and as a result, changes in the topology of the power system and becoming an active network at the level of the distributed network. Despite the existence of many advantages of distributed resources, this issue has caused disruption in the performance of the protection equipment of the distribution network to the point where the conventional methods of modifying the protection settings are not responsive. In this article, there is a comprehensive review on new solutions in the field of modifying and restoring the protection system of distribution networks in the presence of distributed generations. For this purpose, the performance of the protection system has been evaluated. Also, through the general classification of studies conducted in this field, the weak points or strengths of each of the study groups as well as the proposed strategies have been determined.
