Resonance Analysis and Coordinated Active Damping of Multiparallel Grid-Connected Converters Under Filter-Inductance Attenuation and Grid-Strength Variation

Parallel converter operation enables flexible capacity expansion of energy-storage power conversion systems. However, parallel converter interactions, filter-inductor saturation, and grid-strength variations increase the risk of resonance instability. The measured current-inducta...
