Practical framework for frequency stability studies in power systems with renewable energy sources
(IEEE-Inst Electrical Electronics Engineers, 2020)
The transition from power systems dominated by synchronous machines to systems based on converter-based generation technologies (CGTs), is weakening currently robust power systems by reducing system inertia with the ...
Nilpotent Jacobians and Almost Global Stability
(Springer, 2020)
By one hand, we continue with the study of the liaison between the almost Hurwitz vector fields and density functions. In particular by using mapsHwith nilpotent JacobianJHsuch that their rows are linearly dependent over ...
Stability assessment of underground mine stopes subjected to stress relaxation
(Taylor & Francis, 2020)
Stress relaxation plays an important role in the design of underground stopes. The aim of this paper is to assess the stope stability in connection with the stress relaxation using a classification approach. Three types ...
Combined economic and stability analysis of a microgrid: A co-optimisation approach
(IEEE, 2017)
Both economics and stability analysis are critical to operate electricity networks in an efficient and secure manner, especially in the context of microgrids, where more complex stability phenomena ...
Stability of an inverse problem for the discrete wave equation and convergence results
(Elsevier, 2015)
Using uniform global Carleman estimates for semi-discrete elliptic and hyperbolic equations, we study Lipschitz and logarithmic stability for the inverse problem of recovering a potential in a semi-discrete wave equation, ...
Stability of an inverse problem for the discrete wave equation and convergence results
(Elsevier, 2015)
Using uniform global Carleman estimates for semi-discrete elliptic and hyperbolic equations, we study Lipschitz and logarithmic stability for the inverse problem of recovering a potential in a semi-discrete wave equation, ...
A Monte-Carlo approach to the effect of noise on local stability in polynomial difference equations.
(2011-10-13)
We present an analysis of the stability behaviour of a class of one-step difference equations
describing an iterated polynomial mapping. Such equations are commonly used to model population
dynamics in discrete time. We ...
Review on the Stability of the Peregrine and Related Breathers
(Frontiers Media, 2020)
In this note, we review stability properties in energy spaces of three important nonlinear Schrodinger breathers: Peregrine, Kuznetsov-Ma, and Akhmediev. More precisely, we show that these breathers are unstable according ...
Wright type delay differential equations with negative schwarzian
(2003)
We prove that the well-known 3/2 stability condition established for the Wright equation (WE) still holds if the nonlinearity p(exp(-x)-1) in WE is replaced by a decreasing or unimodal smooth function f with f'(0) < 0 ...
A simple test for asymptotic stability in some dynamical systems.
(2015-09-21)
In this paper we analyze asymptotic stability of the dynamical system x˙ = f(x)
defined by a C1 function f : D Rn where D Rn
+ is an open set. We obtain a
criterion of stability for the equilibrium solution ¯x D ...
