Microgrid hierarchical protection architecture
To address these fundamental challenges, this article proposes a zone-based hierarchical protection scheme that par-titions a microgrid into various zones of protection and assigns speed-based hierarchical protection schemes. . High penetration of Renewable Energy Resources (RESs) introduces numerous challenges into the Microgrids (MG), such as supply–demand imbalance, non-linear loads, voltage instability, etc. Hence, to address these issues, an effective control system is essential. Therefore, in this research work, a. . Most existing protection schemes reflecting the current state of the art are suitable for microgrids with mixed types of distributed energy resources (DERs), in-cluding both rotating machine-based DERs as well as IBR-based DERs, where the fault current level is moderately high. Due to the drastic. . The Microgrid (MG) concept is an integral part of the DG system and has been proven to possess the promising potential of providing clean, reliable and efficient power by effectively integrating renewable energy sources as well as other distributed energy sources. This complicates control philosophies and can lead to unintended and unmodelled instabilities in the. . -
