High-capacity long-distance HVDC is indispensable for the centralized integration of deep-sea offshore wind farms and sandy-region renewable energy bases. Hybrid flexible HVDC, which adopts voltage-source converters at the sending end and current-source converters at the receiving end, meets the technical needs and pot...

Rapid growth in renewable generation and electricity-market participation is increasing the number and autonomy of grid-connected resources, challenging conventional centralized energy management systems (EMSs). This paper proposes a cloud–edge collaborative EMS comprising a cloud brain, heterogeneous edge nodes, and a...
A gray-box framework—the Physics-Informed Hybrid Model (PIHM)—that integrates a simplified physical impedance branch with a Bidirectional Long Short-Term Memory (Bi-LSTM) network in a novel parallel architecture is proposed, establishing the PIHM as a reliable, parameter-free tool for impedance-based stability analysis...
