POD utilization methods for STATCOMs

This paper presents a study initiated by the IEEE Working Group 15.05.02 “Dynamic Performance and Modeling of HVDC & FACTS”. The Working Group is concerned with the dynamic performance of HVDC and FACTS devices under different aspects in the time domain and in the frequency domain. Converter and controller modeling, electro-mechanic and electro-magnetic phenomena, and dynamic interaction with the power system is studied carefully. Study results are discussed and recommendations for modeling drawn and published. This paper presents utilization methods for a STATCOM device, which is equipped with a power oscillation damping controller with optimized parameters. Different input signals for the damping controller are studied and compared in the time domain and in the frequency domain. Furthermore, aspects on the dynamic performance and the optimal location in large power systems for damping of inter-area oscillations are studied and discussed.
