Coordinated tuning of multiple power oscillation damping controllers of HVDC links: Application to a large-scale power system

Abstract

This paper uses eigenvalue sensitivities to address the coordinated design of multiple power oscillation damping (POD) controllers of an HVDC-VSC link. Namely, POD controllers modulating the active and reactive power of each pole’s converter are designed. This paper shows the feasibility of applying such an approach to a large-scale power system and the challenges encountered. Moreover, the coordinated design method based on eigenvalue sensitivities has been extended to design POD controllers valid for several operating conditions. In particular, N-1 conditions in the parallel AC lines are considered. The performance of the proposed controller designs is checked in the time and frequency domains.
