Power system dynamic performance: Primary governing frequency response
2009 IEEE Bucharest PowerTech, 2009An efficient ancillary services mechanism implies a good coordination between the regulatory side, transmission system operators and power producers. In continental Europe, ancillary services represent a formal relationship between the actors. The regulatory side establishes recommendations.

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 ...

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

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 ...

Real-Time Central Demand Response for Primary Frequency Regulation in Microgrids
IEEE Transactions on Smart Grid, 2012Summary form only given. Providing ancillary services for future smart microgrid can be a challenging task because of lack of conventional automatic generation control (AGC) and spinning reserves, and expensive storage devices. In addition, strong motivation to increase the penetration of renewable energy in power systems, particularly at the ...

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.

Relating Primary Governing Frequency Response to Future Operating Reliability
2007 IEEE Power Engineering Society General Meeting, 2007The author presents a guide for determining the significance of primary governing frequency response (PGFR) to total interconnection reliability using examples from the North American interconnections. Primary governing frequency response assessments based on measurement methods, failure modes, risk contributors, total risk estimation, and ...

Interruptible Load Constrained Primary Frequency Response Scheduling with Photovoltaic Generation
2018 20th National Power Systems Conference (NPSC), 2018Large penetration of intermittent photovoltaic generation (PV) would pose formidable challenges for utilities, to provide inertial and primary frequency response (PFR). PV generation would reduce the generation share of synchronous generators and hence reduce generator inertia & PFR. This necessitates an additional response from interruptible loads, to

Primary frequency response with stochastic scheduling under uncertain photovoltaic generation
2017 IEEE Power & Energy Society General Meeting, 2017Bulk integration of uncertain PV generation is likely to pose real-time operational challenges for the system operators to provide primary frequency response (PFR). PFR requirement for frequency stability has been recognized widely and its impact on the generation scheduling needs indepth investigation.
