Microgrid hierarchical collaborative protection
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. . Hence, the protection method based on the principle of time and current is difficult to ensure the protection selectivity. This paper proposes a hierarchical collaborative protection method based on the principle of layer-by-layer verification, which uses the evaluation system of system electrical. . 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. There is no guarantee that behavior of DERs will be common amongst device types or even amongst vendors. This complicates control philosophies and can lead to unintended and unmodelled instabilities in the. . This paper presents a hierarchical clustering algorithm approach to the optimal coordination of directional overcurrent relays (OCRs) in microgrids.
