Abstract: Power system (PS) stability is a major concern for an electrical power system (PS) in the past decades. Small signal stability (SSS) is a class of stability of the power system (PS) determined by eigenvalue analysis. The dynamic performance of the linearized power system (PS) model is determined by small signal stability (SSS) analysis by calculation of eigenvalues and eigenvectors of the state matrix. For satisfactory operation of a power system (PS), all modes, i.e. all eigenvalues, must be stable in a power system (PS). Small signal stability (SSS) is a key necessity for power system (PS) to operate successfully. The main objective of this study is to verify the sufficient damping of all modes associated with a system such that transfer of power takes place successfully. Small signal stability (SSS) analysis is performed on the power system (PS) models in MATLAB 7.8.0 with PSAT version 2.1.9 in this paper.
Keywords: Eigenvalue, Inter-area, Power system (PS), Small-signal-stability (SSS).
