Performance Evaluation of a DeMod-CDSC-Based P-Class PMU Under Noisy Conditions

The key contribution is the first systematic noise-robustness assessment of the frequency-adaptive DeMod-CDSC P-class PMU framework, demonstrating superior TVE and FE performance over SOGI-CDSC across 30–80 dB SNR and establishing its suitability for noisy real-world smart-grid applications.
