Identification of maximum inter-area power transfer regions of power networks: Three area problem.

摘要

This thesis is concerned with the identification of maximum regions of inter-area active power transfer, called Load-Flow Feasibility (LFF) regions, for a three-area power system under both normal and contingency operation conditions, as is illustrated in Figure 0-1. The boundary of the LFF region is composed of turning points of bifurcation branches of load-flow equations, i.e., points of voltage collapse. An effective and efficient method, called regularization, is used to identify the turning points. Key issues addressed in this thesis include: theoretical foundation of regularization, selection of regularization functions, turning point calculation and contingency ranking based on the limit of maximum power transfer.(UNFORMATTED TABLE OR EQUATION FOLLOWS){dollar}{dollar}vbox{lcub}vskip108pt{rcub}{dollar}{dollar}(TABLE/EQUATION ENDS)
