Variance‐Empirical Mode Decomposition Method for Fault Detection in MMC‐HVDC Transmission Lines
A variance‐embedded empirical mode decomposition (VEMD) method is proposed for fast and accurate fault detection in MMC‐HVDC transmission lines. By combining variance analysis with EMD, the method reliably detects various faults without communication links and remains robust to noise and non‐fault transients.

Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.
