Title : Modeling and Damping of Renewable Energy and HVDC System Resonances
Abstract:
Resonance is a new challenge faced by the renewable energy and HVDC industry in recent years, having caused various practical problems that range from unacceptable power quality to frequent tripping of protection, and to physical damage of wind turbines, PV inverters and HVDC converters. This lecture presents field measurements and first-hand experiences with such system resonances to identify their common behaviors and characteristics, explain their root causes using sequence impedance models, and review different methods to damp them. Recent advances in the development of power electronics control technologies and industry standards to prevent power system resonances are also reviewed.
