Abstract

In this paper, robust control applications for damping power systems low frequency oscillations (LFOs) are reviewed and compared, to reveal new research directions. With the analysis of LFO through the application of a single-machine infinite-bus (SMIB) model, design methods for Power System Stabilizers (PSSs) can generally be classified into three categories, H_∞ control, H₂ control, and mixed H_∞/H₂ control. With its important role, linear matrix inequality (LMI) has been emphasised in the review of all three types of PSS design. Finally the potential future research directions for novel PSSs is proposed as a reference for interested researchers.
