Aggregation Frequency Response Modeling for Wind Power Plants With Primary Frequency Regulation Service [PDF]
IEEE Access, 2019 High-penetration wind power access to grid requires wind turbine generator (WTG) to provide frequency regulation service. Consequently, the frequency dynamics of wind power plants (WPPs) integrated system are changing; thus, it is necessary to ...

Graph Laplacian Spectrum and Primary Frequency Regulation [PDF]
2018 IEEE Conference on Decision and Control (CDC), 2018 We present a framework based on spectral graph theory that captures the interplay among network topology, system inertia, and generator and load damping in determining the overall grid behavior and performance. Specifically, we show that the impact of network topology on a power system can be quantified through the network Laplacian eigenvalues, and ...

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.

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 ...
