Nonlinear dynamics, 2021 This work shows that chaotic signals with different power spectrum and different positive Lyapunov exponents are robust to linear superposition, meaning that the superposition preserves the Lyapunov exponents and the information content of the source ...

Using Largest Lyapunov Exponent to Confirm the Intrinsic Stability of Boiling Water Reactors
Nuclear Engineering and Technology, 2016 The aim of this paper is the study of instability state of boiling water reactors with a method based in largest Lyapunov exponents (LLEs). Detecting the presence of chaos in a dynamical system is an important problem that is solved by measuring the LLE.

Mitigation of subsynchronous control interaction in DFIGs using active disturbance rejection control
IET Generation, Transmission & Distribution, 2021 Recently, a new type of subsynchronous oscillation (SSO) has occurred in doubly‐fed induction generator (DFIG)‐based wind farms. This oscillation is also called the subsynchronous control interaction (SSCI), which is mainly caused by the interaction ...

Complexity, 2020 In this paper, a multistable modified fourth-order autonomous Chua’s chaotic system is investigated. In addition to the dynamic characteristics of the third-order Chua’s chaotic system itself, what interests us is that this modified fourth-order ...

Scientific African, 2023 In this article, we will propose a new method for encrypting of arbitrary sizes and formats. Based on chaos, this new technique starts with the construction of an S-box of size 16×16, improved by a dynamic behavior and attached to new substitution and ...

Chaos in a nonlinear Lorentz-Lu-Chen system via the fractal fractional operator of Atangana-Baleanu
Interciencia, 2023 This paper establishes the presence or absence of chaotic behaviors in the nonlinear modified Lorentz-L\\\"{u}-Chen using the Atangana-Baleanu fractal-fractional operators. Moreover, we investigate the impact of the fractal-fractional operators on the system\'s behavior and provide insights into the underlying dynamics.

Chance-Constrained AC Optimal Power Flow: A Polynomial Chaos Approach [PDF]
IEEE Transactions on Power Systems, 2019 As the share of renewables in the grid increases, the operation of power systems becomes more challenging. The present paper proposes a method to formulate and solve chance-constrained optimal power flow while explicitly considering the full nonlinear ac

Earth’s Complexity Is Non-Computable: The Limits of Scaling Laws, Nonlinearity and Chaos
Entropy, 2021 Current physics commonly qualifies the Earth system as ‘complex’ because it includes numerous different processes operating over a large range of spatial scales, often modelled as exhibiting non-linear chaotic response dynamics and power scaling laws ...

Sensors, 2016 The efficiency of a wireless power transfer (WPT) system in the radiative near-field is inevitably affected by the variability in the design parameters of the deployed antennas and by uncertainties in their mutual position.
