Practical framework for frequency stability studies in power systems with renewable energy sources
(IEEE-Inst Electrical Electronics Engineers, 2020)
The transition from power systems dominated by synchronous machines to systems based on converter-based generation technologies (CGTs), is weakening currently robust power systems by reducing system inertia with the ...
Methodological approach for defining frequency related grid requirements in low-carbon power systems
(IEEE, 2020)
Moving towards low-carbon electricity systems through the massive deployment of
renewable energy sources (RES) presents a unique opportunity to combat climate change, but it also poses
enormous technical challenges, ...
Robust unit commitment including frequency stability constraints

Frequency stabilization in nonlinear micromechanical oscillators
(Springer, 2012-01)
Mechanical oscillators are present in almost every electronic device. They mainly consist of a resonating element providing an oscillating output with a specific frequency. Their ability to maintain a determined frequency ...
Frequency stabilization by synchronization of Duffing oscillators
(Europhysics Letters, 2016-08-23)
We present analytical and numerical results on the joint dynamics of two coupled Duffing oscillators with nonlinearity of opposite signs (hardening and softening). In particular, we focus on the existence and stability of ...
The role of fast frequency response of energy storage systems and renewables for ensuring frequency stability in future low-inertia power systems
(MDPI, 2021)
Renewable generation technologies are rapidly penetrating electrical power systems, which challenge frequency stability, especially in power systems with low inertia. To prevent future instabilities, this issue should ...
Evaluation of primary stability in modified implants: Analysis by resonance frequency and insertion torque
(2018-06-01)
Background: Changes in the macrogeometry of dental implants are known to influence primary stability and the osseointegration process. Purpose: The purpose of the present in vitro study was to evaluate the mechanical ...
