Abstract
The paper presents the analytical formulae for calculation of the damping and frequency of the electromechanical modes in large interconnected power systems. The system used for the derivation of those formulae had a structure of a rectangular uniform grid of arbitrary dimensions. It is clearly shown that the low frequency inter-area (LFIA) oscillations are fundamental property of the large longitudinal systems. The reasons for poor damping of these modes are analysed. Analytical expressions for the corresponding eigenvectors are also derived and the modal properties of the LFIA oscillations are discussed. Analytically obtained results are verified through numerical simulations. © 2002 Elsevier Science Ltd. All rights reserved.
