Abstract

This paper investigates the critical parameters of power systems which affect the stability of the system. The analysis is conducted on both a single machine infinite bus (SMIB) system and a large multimachine system with dynamic loads. To further investigate the effects of dynamic loads on power system stability, the effectiveness of conventional as well as modern linear controllers is tested and compared with the variation of loads. The effectiveness is assessed based on the damping of the dominant mode and the analysis in this paper highlights the fact that the dynamic load has substantial effect on the damping of the system.

► Investigation of dynamic loads effects on the stability of interconnected power systems. ► Identification of critical parameter that affects the stability of power systems with dynamic loads. ► Performance analysis of conventional and modern linear controllers with the variation of dynamic loads.
