Chaotic oscillation will occur in power system when there exist periodic load disturbances. In order to analyze the chaotic characteristics and suppression method, this paper establishes simplified mathematical model of interconnected two-machine analyzes nonlinear dynamic behaviors, such as phase diagram, dissipation, bifurcation map, spectrum, Lyapunov exponents. Based on fractional calculus ...

This paper proposes a new PSS design method that takes into account the robustness for comparatively large power systems. The proposed method is a parameter determination scheme for a standard PSS by using Particle Swarm Optimization (PSO). In order to deal with large-scale systems, a reduced model is developed to get the target system, which preserves major oscillation modes only. The major os...

As an interconnected power system via a High-Voltage Direct Current (HVDC) link is subjected to a rapid load change with the frequency of inter-area oscillation mode, system frequency and tie line power may be severely disturbed and oscillate. To compensate for the rapid load change and stabilize both frequency and tie line power oscillations due to the inter-area mode, the dynamic power flow c...
