Abstract
- Reliable protection of distribution systems is becoming increasingly challenging with growing distributed energy resources (DERs) and microgrids. Existing adaptive overcurrent relaying (AOCR) schemes are vulnerable to DER ride-through and generally focus on only grid or islanded modes. This paper presents a dynamic AOCR scheme independent of external controllers to estimate relay pickup that ensures significantly less communication overhead. Existing and emerging challenges for the state-of-the-art are discussed and resolved using the proposed scheme. The reliability is tested using transient system models in Simulink for all combinations of state and fault types/impedances in a 15-bus distribution system. [ABSTRACT FROM AUTHOR]
