Oscillations in Renewable Energy Power Generation and Transmission Systems and Its Mitigation


The Department of Electrical & Computer Engineering at McGill University and the Power Electronics Society chapter in collaboration with the Industry Applications SocietyPower & Energy Society and Industrial Electronics Society chapters in the IEEE Montreal Section cordially invite you to a seminar presented by Dr. Qirong Jiang, professor from the Department of Electrical Engineering in Tsinghua University, Beijing, China.

Presentation Abstract:

Oscillations in Renewable Energy Power Generation and Transmission Systems are very common. Features of the oscillations and challenges in oscillation analysis and its mitigation will be discussed. A PMSG-based wind power system with positive damping for small perturbation and negative damping for large disturbance will be introduced. The characteristics and mechanism of frequency coupling phenomenon in oscillations of voltage source converter (VSC) will be presented. The coupling mechanism and frequency distribution characteristics of the three coupling paths in a VSC controller: phase-locked loop (PLL), DC voltage fluctuation and over-modulation will be analyzed. Controller design to suppress oscillations of multi-scale nonlinear systems will be discussed. STATCOM-based sub-synchronous control interactions mitigation algorithm for DFIG-based wind farms will be presented.
