N2 - This paper presents impedance-model-based stability analyses of power synchronization control (PSC) and two types of vector controls used in voltage source converter-based high voltage direct current (VSC-HVDC) systems. The impedance model of a VSC with PSC is first derived. Stability analysis is then carried out using multi-input multi-output (MIMO) system analysis. As a comparison, power and angle transfer function-based analysis is also conducted. The impedance model-based stability analysis results are validated by the time-domain simulations. Impedance models of two types of vector controls are also derived for comparison. Effects of short circuit ratio (SCR), power transfer level, high-pass filters, and the PSC gain are demonstrated through analysis and real-time digital simulations in RT-LAB.
