Abstract
One of the power system crucial problems for stability is the oscillation at low frequencies. The low frequency oscillation (LFO) is a small signal stability of the power system and has a passive impact on the maximum power transfer (load flow) in power systems. The inter area oscillation using eigenvalue method is presented and analyzed by modeling and linearizing the system around the operating point. This paper introduces the inter area oscillation using Eigen value method by presenting and discussing a proposed power system of two-area, 4-machine into two different cases: The first case is the system running without power system stabilizer, and the second case is to deploy the power system stabilizer firstly in area 1 afterwards area 2 and finally in the two areas at the same time. The advantage of the damping of oscillations is found clearly in the system ability to increase the tie-line power flowing in the proposed system. All simulations results are carried out using MATLAB software.
