Hopf Bifurcation Control of Subsynchronous Resonance Utilizing UPFC

Engineering, Technology & Applied Science Research, 2017
The use of a unified power flow controller (UPFC) to control the bifurcations of a subsynchronous resonance (SSR) in a multi-machine power system is introduced in this study. UPFC is one of the flexible AC transmission systems (FACTS) where a voltage source converter (VSC) is used based on gate-turn-off (GTO) thyristor valve technology.

Investigation of the Stability of the Cameroon Northern Interconnected Grid (NIG): A Transient Analysis

Journal of Control Science and Engineering, Volume 2025, Issue 1, 2025.
Today, the grid has become more complex, and this complexity has exposed it to several unforeseen events that can affect its stability in ways such as component outage, sudden variation in loads, connection of a new generator, and faults. One way to assess the grid’s ability to withstand substantial disturbance is the application of transient stability
