Cs. Chang et al., DYNAMIC-SECURITY-CONSTRAINED MULTIOBJECTIVE GENERATION DISPATCH OF LONGITUDINALLY INTERCONNECTED POWER-SYSTEMS USING BICRITERION GLOBAL OPTIMIZATION, IEEE transactions on power systems, 11(2), 1996, pp. 1009-1016
This paper is devoted to the dynamic performance assessment and model
reduction for a longitudinally interconnected power system, with speci
al emphasis on small-perturbation stability. A 2-machine equivalent is
established for representing intersubsystem behavior of the test syst
em, that is valid over a large range of interconnected system operatio
n. Eigenvalue-sensitivity- based constraints are derived to represent
variations of security levels with MW transfers between subsystems. Th
ese constraints dan be stored in simple lookup tables and are used td
extend the authors' work on a bicriterion optimization approach for de
termining the most appropriate generation dispatch solution taking int
o account the fuel and environmental costs, and to provide security co
nstraints during optimization.
