Physics-informed transient stability assessment of microgrids

open access: yesiEnergy, 2023
With the integration of a voltage source converter (VSC), having variable internal voltages and source impedance, in a microgrid with high resistance to reactance ratio of short lines, angle-based transient stability techniques may find limitations ...

Kuhn-Tucker-based stability conditions for systems with saturation [PDF]

open access: yes, 2001
This paper presents a new approach to deriving stability conditions for continuous-time linear systems interconnected with a saturation. The method presented can be extended to handle a dead-zone, or in general, nonlinearities in the form of piecewise ...

Lyapunov Function and Exponential Trichotomy on Time Scales

open access: yesDiscrete Dynamics in Nature and Society, 2011
We study the relation between Lyapunov function and exponential trichotomy for the linear equation 𝑥Δ=𝐴(𝑡)𝑥 on time scales. Furthermore, as an application of these results, we give the roughness of exponential trichotomy on time scales.

Explicit Reference Governor for Continuous Time Nonlinear Systems Subject to Convex Constraints [PDF]

open access: yes, 2014
This paper introduces a novel closed-form strategy that dynamically modifies the reference of a pre-compensated nonlinear system to ensure the satisfaction of a set of convex constraints.

Large-Signal Stability Modeling for the Grid-Connected VSC Based on the Lyapunov Method

open access: yesEnergies, 2018
In this paper, a Lyapunov-based method is used in order to determine the stability boundaries of the grid-connected voltage source converter (VSC). To do so, a state space model of the VSC is used to form the Lyapunov function of the system.

Limits of relative entropies associated with weakly interacting particle systems [PDF]

open access: yes, 2015
The limits of scaled relative entropies between probability distributions associated with N-particle weakly interacting Markov processes are considered. The convergence of such scaled relative entropies is established in various settings. The analysis is

Discretized Lyapunov Function Approach for Switched Linear Systems under Dwell Time Constraint

open access: yesAbstract and Applied Analysis, 2014
This paper is concerned with the stability and disturbance attenuation properties of switched linear system with dwell time constraint. A novel time-scheduled Lyapunov function is introduced to deal with the problems studied in this paper. To numerically

Mathematical modelling of branched hydraulic systems [PDF]

open access: yesКомпьютерные исследования и моделирование, 2009
Solving the problem of stationary stream distribution for an arbitrary volume-free hydrosystem with a free level can be reduced to determining the extremes of a multi-variable function.

Time-dependent mode structure for Lyapunov vectors as a collective movement in quasi-one-dimensional systems

open access: yes, 2004
Time dependent mode structure for the Lyapunov vectors associated with the stepwise structure of the Lyapunov spectra and its relation to the momentum auto-correlation function are discussed in quasi-one-dimensional many-hard-disk systems. We demonstrate
