A Frequency-Domain Stability Margin Indicator for Grid-Connected Converter Systems
Paper i proceeding, 2025
Grid-connected converter systems with multiple control loops impact grid stability, especially with increasing renewable energy penetration. This paper proposes a frequency-domain stability margin indicator that simplifies stability assessment by reducing complexity and linking stability margins to system properties. Validated for SISO systems and extended to MIMO systems, the indicator effectively identifies stability margins and predicts the system robustness.
