A control strategy for a grid-connected virtual synchronous generator with virtual impedance

open access: yesEnergy Reports, 2023
Virtual synchronous generator (VSG) can simulate synchronous generator turning and damping characteristics, which can further improve the penetration rate of renewable energy in the grid.

Research on the Operation Control Strategy of a Low-Voltage Direct Current Microgrid Based on a Disturbance Observer and Neural Network Adaptive Control Algorithm

open access: yesEnergies, 2019
Low-voltage direct current (DC) microgrid based on distributed generation (DG), the problems of load mutation affecting the DC bus under island mode, and the security problems that may arise when the DC microgrid is switched from island mode to grid ...

Theta synchronization over occipito‐temporal cortices during visual perception of body parts [PDF]

open access: yes, 2018
Categorical clustering in the visual system is thought to have evolved as a function of intrinsic (intra-areal) and extrinsic (interareal) connectivity and experience.

Intermittent generalized synchronization in unidirectionally coupled chaotic oscillators

open access: yes, 2005
A new behavior type of unidirectionally coupled chaotic oscillators near the generalized synchronization transition has been detected. It has been shown that the generalized synchronization appearance is preceded by the intermitted behavior: close to ...

Data-Driven Optimal Synchronization for Complex Networks With Unknown Dynamics

open access: yesIEEE Access, 2020
This paper studies the data-driven optimal synchronization problem for complex networks (CNs) with unknown dynamics. By using pre-compensation technology, a compensator and a controller are proposed.

Synchronization and Control in Intrinsic and Designed Computation: An Information-Theoretic Analysis of Competing Models of Stochastic Computation

open access: yes, 2010
We adapt tools from information theory to analyze how an observer comes to synchronize with the hidden states of a finitary, stationary stochastic process.

Simulation of 1 x 2 OTDM router employing symmetric Mach-Zehnder switches [PDF]

open access: yes, 2005
In high-speed all-optical time division multiplexed (OTDM) routers it is desirable to carry out data routing, switching, clock recovery and synchronisation in the optical domain in order to avoid the bottleneck due to optoelectronics conversion.
