Abstract

This paper presents a computer simulation of coherency-based dynamic equivalents for the reduction of large power systems for faster transient stability studies applicable in academic and research fields. The simulation decomposes the power system generators into the study and external areas by computing the power deviation of all generators during a fault. The simulation features the computation of admittance distance, inertia and damping indices for the identification of coherent machines, and dynamic equivalents. The simulation tool comprises a set of scripts that were developed on the MATLAB platform and are easily operated through the use of the Command window. The theoretical formulations of the algorithms implemented by this simulation are described while its computational extensiveness is tested with the IEEE 10 generator 39-bus system and the Nigeria power system. The illustrative approach in this paper provides a more practical approach to dynamic equivalents based on coherent generators by expounding relevant theoretical and computational ideas.
