Time Delay in the Swing Equation: A Variety of Bifurcations
Tessina H. Scholl, Lutz Gröll, Veit Hagenmeyer
The present paper addresses the swing equation with additional delayed damping as an example for pendulum-like systems. In this context, it is proved that recurring sub- and superc…
Characteristics-based Simulink implementation of first-order quasilinear partial differential equations
Anton Ponomarev, Julian Hofmann, Lutz Gröll
The paper deals with solving first-order quasilinear partial differential equations in an online simulation environment, such as Simulink, utilizing the well-known and well-recomme…
On Norm-Based Estimations for Domains of Attraction in Nonlinear Time-Delay Systems
Tessina H. Scholl, Veit Hagenmeyer, Lutz Gröll
For nonlinear time-delay systems, domains of attraction are rarely studied despite their importance for technological applications. The present paper provides methodological hints…
Probabilistic Energy Forecasting using Quantile Regressions based on a new Nearest Neighbors Quantile Filter
Jorge Ángel González Ordiano, Lutz Gröll, Ralf Mikut +1
Parametric quantile regressions are a useful tool for creating probabilistic energy forecasts. Nonetheless, since classical quantile regressions are trained using a non-differentia…
