Abstract
This paper proposes an algorithm for determining a minimum generation redispatch capable of moving specific oscillation modes to the closest small-signal security boundary that guarantees them a desired damping factor. The algorithm combines nonlinear optimization techniques with numerical eigenvalue sensitivities obtained from multiple runs of a load flow solver and partial eigensolutions. The algorithm, namely Closest Security Boundary for Generation Redispatch using Eigenvalue Sensitivities (CSBGRES) relies on sparse matrices and is applicable to large-scale power systems. The work presents results on the Brazilian Interconnected Power System (BIPS) and the Nordic 44 Test System (N44S).
