Complex-Network-Guided High-Risk Substation Identification and Targeted Mitigation of Transformer DC Bias in Multi-Infeed UHVDC Receiving-End Grids

In multi-infeed UHVDC receiving-end grids, transformer DC-bias risk is affected not only by the magnitude of grounding-electrode current, but also by the AC-grid topology, substation grounding condition, voltage-level-dependent current limits, and polarity coordination among grou...
