Multi-parameter Bifurcation Analysis of Power Systems
نویسندگان
چکیده
This paper presents a detailed bifurcation analysis of multi-parameter power systems. Equilibrium points are used to evaluate the system eigenvalues and obtain different bifurcation diagrams for two sample systems. The paper studies the influence of hard-limits, AVR droop and reactive power compensation on the local bifurcations of the test systems, using detailed generator models. The stability regions of equilibrium points and the effect that various bifurcations have on them are also studied.

Guaranteeing Dynamic Performance in Nonlinear Non-smooth Power Systems
Performance specifications place restrictions on the dynamic response of many systems, including power systems. It is often convenient to know parameter values that induce limiting behaviour, i.e., force the system to just meet the specification. This limiting behaviour is a form of grazing bifurcation, and can be formulated as a boundary value problem. The paper develops a numerical shooting m...
متن کاملAnalysis of subsystem integration in aircraft power distribution systems
Stability analysis of a baseline power system architecture for modern aircraft is addressed. Power electronic converters are widely used in modern aircraft power distribution systems. Due to their inherent nonlinear characteristics, instabilities may arise while integrating individual subsystems together. Bifurcation analysis is used to identify the type, multiplicity and stability of system tr...
متن کاملA New Bifurcation Analysis for Power System Dynamic Voltage Stability Studies
The dynamic of a large class of power systems can be represented by parameter dependent differential-algebraic models of the form ) , , ( p y x f x = • and ) , , ( 0 p y x g = . When the parameter p of the system (such as load of the system) changes, the stable equilibrium points may lose its dynamic stability at local bifurcation points. The systems will lose its stability at the feasibility b...
متن کاملTwo-Parameter Bifurcation Analysis of the Buck Converter
This paper is concerned with the analysis of two-parameter bifurcation phenomena in the buck power converter. It is shown that the complex dynamics of the converter can be unfolded by considering higher codimension bifurcation points in two-parameter space. Specifically, standard smooth bifurcations are shown to merge with discontinuity-induced bifurcation (DIB) curves, giving rise to intricate...
متن کاملAnalysis of chaotic vibration in a hexagonal centrifugal governor system
In this paper, the periodic, quasi periodic and chaotic responses of rotational machines with a hexagonal centrifugal governor are studied. The external disturbance is assumed as a sinusoid effect. By using the forth order Rung-Kutta numerical integration method, bifurcation diagram, largest Lyapunov exponent and Lyapunov dimension are calculated and presented to detect the critical controlling...
