Mutual synchronization and clustering in randomly coupled chaotic dynamical networks [PDF]

, 1999
We introduce and study systems of randomly coupled maps (RCM) where the relevant parameter is the degree of connectivity in the system. Global (almost-) synchronized states are found (equivalent to the synchronization observed in globally coupled maps ...

Anticipating the dynamics of chaotic maps

, 2002
We study the regime of anticipated synchronization in unidirectionally coupled chaotic maps such that the slave map has its own output reinjected after a certain delay.

Transient stability and FRT technologies of different synchronous wind turbine

Energy Reports, 2022
With the global energy transformation towards to a 100% renewable-based power system, the installed capacity of renewable energy generation has continued to grow rapidly in recent years. At the same time, due to the loss of synchronous machines, the grid-connected large-scale renewable energy bring great challenges to the safe and stable operation of ...

Growth, collapse, and self-organized criticality in complex networks

, 2016
To understand how certain dynamical behaviors can or cannot persist as the underlying network grows is a problem of increasing importance in complex dynamical systems as well as sustainability science and engineering. We address the question of whether a

Comparative analysis of existing models for power-grid synchronization

, 2015
The dynamics of power-grid networks is becoming an increasingly active area of research within the physics and network science communities. The results from such studies are typically insightful and illustrative, but are often based on simplifying ...

Impedance Estimation for Transient Stability Enhancement of Virtual Synchronous Machines

2024 IEEE 15th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)
In this paper, a passive technique for estimating the impedance and voltage of a Thévenin grid is presented. The method can be applied when either the maximum active power or minimum reactive power operating point, with respect to the power angle, is crossed. This work addresses transient events, for which the former occurs.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Synchronization of many nano-mechanical resonators coupled via a common cavity field [PDF]

, 2011
Using amplitude equations, we show that groups of identical nano-mechanical resonators, interacting with a common mode of a cavity microwave field, synchronize to form a single mechanical mode which couples to the cavity with a strength dependent on the ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
