A multi‐side‐reaction electrochemical model is developed to predict lithium‐ion battery degradation under high temperatures, incorporating SEI growth, electrode cracking, and electrolyte oxidation. The model shows strong agreement with experimental results, enabling accurate cycle life prediction and identification of dominant aging mechanisms ...

Multi‐Layer MTDC Protection: Design and Simulation Assessment
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...

Application of T&D Circuit Segmentation for Improved Resilience—A Texas Case Study
ABSTRACT Several lessons were learned from the post‐analysis of 2021 Winter Storm Uri's devastating impact on Texas's electricity grids. Among the lessons was the need for greater granularity and flexibility in how Texas electricity utilities shed load during emergencies, as directed by the local Independent System Operator (ISO), while protecting ...
