STATCOM with optimized POD controller for efficient inter-area oscillation damping

The work presented in this paper was developed during studies for the IEEE Working Group 15.05.02 “Dynamic Performance and Modeling of HVDC & FACTS”. The Working Group was initiated with the main task to study 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 are of main interest. This paper utilizes a STATCOM with a supplementary power oscillation damping control function and discusses aspects on the dynamic performance and the optimal location in large power systems for damping of inter-area oscillations. The power oscillation damping controller is optimized using parameter identification.
