Transient Stability Evaluation and Decoupled Control for Grid-Following Converters Considering Nonideal Alternating Current Control

IEEE transactions on power electronics
In most previous studies about transient synchronization stabilities of grid-following converters (GFLC), alternating current control (ACC) dynamics are often neglected.

Unveiling the Causal Role of Auditory Theta Rhythms in Musical Pleasure: A Transcranial Alternating Current Stimulation/Electroencephalogram Study.

Journal of Cognitive Neuroscience
The enjoyment of music involves a complex interplay between brain perceptual areas and the reward network. While previous studies have shown that musical liking is related to an enhancement of synchronization between the right temporal and frontal brain ...

Placement multi flexible alternating current transmission system (FACTS) : Static var compensator (SVC) and static synchronous compensator (STATCOM) for improving voltage stability of 500 KV Java-Bali electrical power system

AIP Conference Proceedings, 2020
Demand for electricity is increasing rapidly, the consequence of this is a threat to the stability of the electrical system, one of which is the voltage stability. FACTS or flexible alternating current transmission system is an electronic equipment capable of regulating electrical power transmission that can be used to overcome stability problems. This

Synchronous alternating current motor and mechanical vibrating system maintained by a thermionic valve at the frequency of the vibrating system

Proceedings of the Physical Society, 1926
The design of a chronograph which will give a time trace subdivided into units and fractional units requires the association of a rotating system and a vibrating or time-keeping system. It a low-frequency vibrating system be employed, the rotating system, although keeping good average time, may show exaggerated errors in unit subdivisions due to ...

Resource-Aware Grid-Forming Synchronization Control: Design, Analysis and Validation

IEEE transactions on energy conversion
This paper presents a power-synchronization loop scheme for renewable power generation operated in Grid-Forming (GFM), which considers the DC-connected resource limitations. Under conditions where the resource might not be able to provide the Alternating

Using analytical signals and synchronous detection to obtain signals of skin galvanic activity on alternating current

Biomedical Radioelectronics
The interest in the skin galvanic channel for obtaining information about a person's condition is related to the fact that these signals mainly arise as a result of higher nervous activity. This makes them interesting in a number of practical applications, such as lie detectors, devices for monitoring the ability of operators, etc.
