  • Analysis of Time Delay Effects for Wide-Area Damping Control Design using Dominant Path Signals

    • The purpose of this article is to investigate the effects of time delays for wide-area damping control design when signals from dominant inter-area oscillation paths are used as feedback inputs for damping controllers. The analysis is carried out using a two-area study system. Frequency and time-domain responses of a generator's terminal voltage when the PSS uses PMU signals subject to time delays will be compared and assessed. The analysis reveals that while modal observability of the dominant path signals corresponds to the gain of the open-loop system at the inter-area frequency, these properties are inversely proportional to their corresponding delay margins.

  • Coherency-Independent Structured Model Reduction of Power Systems
  • 2014
  • Ingår i: IEEE Transactions on Power Systems. - 0885-8950 .- 1558-0679. ; 29:5, s. 2418-2426
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper proposes a new model reduction algorithm for power systems based on an extension of balanced truncation. The algorithm is applicable to power systems which are divided into a study area which requires a high-fidelity model and an external area, making up most of the power system, which is to be reduced. The division of the power system can be made arbitrarily and does not rely on the identification of coherent generators. The proposed algorithm yields a reduced order system with a full non-linear description of the study area and a reduced linear model of the external area.
