Optimal Coordination of Directional Overcurrent Relays in Meshed Active Distribution Network Using Imperialistic Competition Algorithm

Journal of Modern Power Systems and Clean Energy, 2021
The optimal setting of directional overcurrent relays (DOCRs) ensures the fault detection and clearing in the minimum possible operation time. Directional protective relaying is carried out to coordinate relay settings in a meshed network in the presence

Enhancing distribution generator impact mitigation using an adaptive protection scheme based on modified pelican optimization algorithm and active database management system

Energy Science &Engineering, Volume 11, Issue 11, Page 4108-4127, November 2023., 2023
The use of distribution generators affects fault currents, leading to miscoordination between protection relays and causing constraints on network reliability. To tackle this issue, an adaptive protection scheme (APS) based on a modified pelican optimization algorithm (MPOA) and active database management system is proposed.

A new protection algorithm for tackling the impact of fault‐resistance and cloud energy storage on coordination of recloser‐fuse protection

IET Generation, Transmission &Distribution, Volume 17, Issue 8, Page 1827-1835, April 2023., 2023
This paper is aimed at recloser‐fuse protection in CESS employed multi‐microgrid distribution systems for improving the fuse saving task and mitigating the fault resistance effects. In this way, after applying the conventional recloser‐fuse protection scheme, a new scheme is presented to improve the performance of the system in presence of CESS and ...
