Krylov Subspace Methods in Power System Studies

136 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2001.Power system applications are computationally intense, and therefore there is a need to develop new methods for performing these calculations. This study proposes the use of numerical methods based on the Krylov subspace methodology on four areas of power systems: the power flow problem, the dynamic simulation, the trajectory sensitivity analysis and the model reduction. Krylov subspace techniques are tested and compared with traditional approaches. Additionally, a physical interpretation of this methodology is investigated, and links with well-established concepts in power systems are attempted.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
