Comparative Ranking of Critical Uncertainties Affecting the Stability of Mixed AC/DC System

Power systems are accommodating ever-increasing sources of uncertainty due to the proliferation of renewable energy sources (RES). With increased uncertainties in the system, it is very important to assess the stability of power systems in a probabilistic framework. Subsequently the most critical uncertainties need to be identified to enable targeted mitigation strategies but these might change in different operating conditions and for various types of stability concerns. This abstract presents a comparative ranking of critical uncertainties using Pearson correlation coefficient for various stability studies, namely large and small-disturbance rotor angle, frequency and voltage stability. Priority raking will be performed (in the full paper) using further sensitivity analysis techniques, including local, screening and global methods. Illustrative results are presented with a modified version of the Kundur two area power system including HVDC interconnections and RES. Preliminary results show that the most critical parameters vary significantly for various types of stability studies.
