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 ...

Multi‐vendor interoperability in HVDC grid protection: State‐of‐the‐art and challenges ahead
IET Generation, Transmission &Distribution, Volume 15, Issue 15, Page 2153-2175, August 2021., 2021 Abstract Multi‐vendor interoperable HVDC grid protection is key to build large‐scale HVDC grids in a step‐by‐step manner. On the one hand, various protection strategies and technologies have been developed in the past decade to address the challenges associated with HVDC grid protection.

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 ...
