This paper proposes integrating polyether ether ketone (PEEK) with a synthetic ester liquid as the composite insulation system for subsea cable connectors. The study commences with a comparative analysis of the electrical performance of PEEK when immersed in a synthetic ester liquid and a mineral oil.

This study develops a data‐driven hybrid framework for assessing the condition and risk of converter stations. By combining adaptive thresholding, a condition assessment algorithm and a two‐stage Weibull failure model, it enables early fault detection and quantification of equipment degradation. Case study shows enhanced sensitivity to latent failures,

This research presents a robust protection coordination strategy using dual‐setting directional overcurrent relays (DS‐DOCRs) and a novel optimisation approach to address challenges in adaptive protection. A modified objective function, incorporating primary and backup relay operating times along with coordination time intervals (CTIs), is designed to ...

A multi‐source data collaborative fault section identification method for high fault‐tolerant distribution networks is proposed. The method constructs a robust mixed‐integer linear programming cooperative model by integrating zero‐sequence current direction features and fault indicator alarm signals.

This paper proposes a closed‐form analytical framework predicting the sub‐cycle transient peak currents of grid‐following and grid‐forming inverters during short‐circuit faults. The method uniquely decouples the fault current into a hardware natural response and a control‐commanded response, enabling rapid estimation of instantaneous initial peaks ...

This paper maps key 5G technology enablers, such as carrier aggregation, dual connectivity, and network slicing (NS), to IEC 61850 smart grid communication traffic types and experimentally evaluates their performance in commercial 5G networks. Results show that NS enhances reliability for grid protection and automation but still falls short of ultra ...

Precise Hybrid Method for Solving the Selectivity Problem of Overcurrent Relays due to PV Uncertainty [PDF]
Photovoltaic (PV) power plants include several parallel and series units. PV uncertainty due to scheduled or forced outages of these units affects the coordination of overcurrent relays (OCRs) and may violate the optimization constraint.
