A distributed adaptive protection scheme based on multi‐agent system for distribution networks in the presence of distributed generations

IET Generation, Transmission &Distribution, Volume 16, Issue 8, Page 1521-1540, April 2022., 2022
Abstract Distribution networks are operated in different conditions and the traditional protection systems might not be proper for all available operation conditions by using directional overcurrent relaying. Besides, the presence of distributed generations makes the protection setting and coordination more complex, and may even make it impossible to ...

Intelligent protection coordination restoration strategy for active distribution networks

IET Generation, Transmission &Distribution, Volume 16, Issue 3, Page 397-413, February 2022., 2022
Abstract Despite various advantages of integrating distributed generation (DG) units into distribution networks such as power loss reduction and voltage profile improvement, they may disrupt the performance of the conventional protection system due to bidirectional power flow and change of short‐circuit power.

Adaptive scheme protecting renewable‐dominated micro‐grids against usual topology‐change events

IET Renewable Power Generation, Volume 15, Issue 12, Page 2686-2698, 7 September 2021., 2021
Abstract Miscoordination and faulty operation are the two main protection challenges of renewable Distributed Generations (DGs) in Distribution Networks (DNs) and Micro‐Grids (MGs). Although various approaches have already been presented in the literature, none of them has proposed a solution for simultaneous impact of DN/MG reconfigurations and DGs ...

Overcurrent protection based on ANNs for smart distribution networks with grid‐connected VSIs

IET Generation, Transmission &Distribution, Volume 15, Issue 7, Page 1159-1174, April 2021., 2021
Abstract Recently, the global concern for protection coordination is growing with the impact of distributed generators connected to medium voltage distribution system. Effective protection strategies need to be developed in order to avoid undesirable tripping when distributed generators based on Voltage Source Inverters are connected to the medium ...
