Application of Bang–Bang Controller to Emulate Primary Frequency Response in DFIGs
IEEE Systems Journal, 2020This article proposes a bang–bang auxiliary frequency control scheme for doubly-fed induction generator (DFIG)-based wind turbines. It results in the DFIGs emulate the primary frequency control of conventional units and, thus, increases the power system frequency stability.

Market designs for the primary frequency response ancillary service
2014 IEEE PES General Meeting | Conference & Exposition, 2014The first part of this two-paper series discusses the motivation of implementing a primary frequency response (PFR) market in restructured pool-based power markets, as well as the market design that would create the right incentives to provide the response reliably.

Primary Frequency Response in Capacity Expansion With Energy Storage
IEEE Transactions on Power Systems, 2018Massive integration of renewable energy resources calls for new operating and planning paradigms, which address reduced controllability and increased uncertainty on the generation side. On the other hand, emerging energy storage technologies can provide additional flexibility. Therefore, generation and storage expansion models need to be coordinated to

Economic impact of wind integration on Primary Frequency Response
2015 IEEE Eindhoven PowerTech, 2015In order to have a reliable and secure power system, frequency stability should be guaranteed. Primary Frequency Response (PFR) is used to arrest the frequency deviation upon a contingency. The significant penetration of wind generation in power grids has negative effect on the PFR, as the contribution of wind machines to the total system inertia is ...

Delivery of Primary Frequency Response over Weak Electrical Paths
2021 IEEE Madrid PowerTech, 2021Replacement of rotating machine generation sources with inverter based resources can change the trajectory of the primary frequency response. As generation sources interconnect to weak areas of the network and move farther away from loads, the time taken for a source to respond to a disturbance can get longer and the effective magnitude of the response

The alteration of the low frequency response of primary auditory afferents by cochlear trauma
Hearing Research, 1983The response phase of primary auditory afferents in the first turn of the guinea pig cochlea to low frequency sinusoidal stimuli is altered by trauma to the cochlea. Loud sounds of sufficient intensity to produce temporary shifts in the thresholds of these cells at their characteristic frequency produce a reversal of the neural response from increased ...

Scheduling BESS for Primary Frequency Response in Low Inertia Grids
2020 IEEE 9th Power India International Conference (PIICON), 2020The integration of intermittent renewable energy sources (RES) would challenge system operators to ensure the required system inertia (SI) and primary frequency response (PFR). The decline in response would arise system security and reliability concerns due to post fault frequency dynamics during contingency like the largest generation or load loss ...

High Frequencies of Response After Limited Primary Therapy for Multiple Myeloma
Clinical Lymphoma Myeloma and Leukemia, 2013In an effort to maintain high primary response rates against multiple myeloma and without serious toxicity, we assessed 3 different bortezomib combinations in small numbers of patients, with combinations that included cyclophosphamide and lenalidomide in modest doses and for short courses. Remissions occurred in approximately 90% of patients, with rare

Frequency response of primary resonance of electrostatically actuated CNT cantilevers
Nonlinear Dynamics, 2014This paper deals with electrostatically actuated carbon nanotube (CNT) cantilever over a parallel ground plate. Three forces act on the CNTs cantilever, namely electrostatic, van der Waals, and damping. The van der Waals force is significant for values of 50 nm or less of the gap between the CNT and the ground plate.
