Arousal regulates frequency tuning in primary auditory cortex [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Changes in brain state modulate how information is processed in sensory cortical areas. Here we use population imaging and intracellular recording to show that arousal regulates frequency tuning in layer 2/3 of primary auditory cortex.

Dual-loop primary frequency regulation controller for VSC-HVDC system [PDF]
2017 IEEE Manchester PowerTech, 2017 This paper presents a frequency control mechanism for an AC system through the active and reactive power loops of a VSC-HVDC system. The proposed scheme makes use of the reactive power loop for inertia support by exploiting the voltage-power sensitivity of loads, and active power droop control has been used to provide governor-like support following ...

Autonomous Demand Response for Primary Frequency Regulation [PDF]
, 2012 The research documented within this report examines the use of autonomous demand response to provide primary frequency response in an interconnected power grid. The work builds on previous studies in several key areas: it uses a large realistic model (i.e., the interconnection of the western United States and Canada); it establishes a set of metrics ...
