| Sumario: | With the increasing presence of power electronics, stability issues in modern power systems are on the rise. The positive-mode-damping (PMD) stability criterion was recently introduced as a simple and practical method based on resonance mode analysis to assess stability in multi-terminal power electronics-based systems. This paper extends the PMD stability criterion by introducing the damping conductance margin (DCM), a novel damping margin indicator to measure the degree of stability in multi-terminal power electronics-based systems. Additionally, it presents two bandpass filter-based active and passive damping compensators to enhance stability and investigates their design using the DCM. Moreover, the modified modal sensitivity method is applied to determine the influence of compensators and VSCs on resonances and their potential interactions. The results are validated by MATLAB/Simulink simulations on the IEEE 3-, 5-, and 14- bus power systems. |
