This paper proposes a new approach for slow coherency identification in large multi-machine power systems based on inter-area oscillation analysis and electrical proximity. To identify the oscillation modes, the participation factors of the state variables are analysed. The proposed method is applied to a real 1475 bus power system with 50 generators.
