Microwave spectroscopy of the Mars atmosphere [PDF]
, 1995 A study of the use of millimeter-wavelength spectral transitions to investigate the atmosphere of Mars is presented. In the model experiments investigated it is assumed that a spectrometer in the frequency range from 100 to 260 GHz looks into a modest ...

Flexible Kinetic Energy Release Controllers for a Wind Farm in an Islanding System
Energies, 2020 To improve frequency nadir following a disturbance and avoid under-frequency load shedding, two types of flexible kinetic energy release controllers for the doubly fed induction generator (DFIG) are proposed.

Effective Inertial Response With New Coordinated Control for Multiple WPPs
IEEE Access, 2022 This paper proposes a new coordinated control for multiple wind power plants (WPPs) based on two stepwise inertial control (SIC) methods to effectively release the kinetic energy of the permanent magnet synchronous generators (PMSGs) and improve their ...

Frequency and Severity of Neutropenia Associated with Food and Drug Administration Approved and Compounded Formulations of Lomustine in Dogs with Cancer. [PDF]
, 2015 BackgroundCompounded lomustine is used commonly in veterinary patients. However, the potential variability in these formulations is unknown and concern exists that compounded formulations of drugs may differ in potency from Food and Drug Administration ...

Continuous and discontinuous dark solitons in polariton condensates [PDF]
, 2014 Bose-Einstein condensates of exciton-polaritons are described by a Schr\"odinger system of two equations. Nonlinearity due to exciton interactions gives rise to a frequency band of dark soliton solutions, which are found analytically for the lossless ...

Dynamic synthetic inertial control method of wind turbines considering fatigue load
Frontiers in Energy Research, 2023 This paper proposes a dynamic synthetic inertia control method, considering the fatigue loads of the wind turbine. The control objectives include reducing the rate of change of frequency and frequency nadir of the power system and the fatigue load of the

An Improved Droop Control Scheme of a Doubly-Fed Induction Generator for Various Disturbances
Energies, 2021 Doubly-fed induction generators (DFIGs) participate in the system frequency regulation using a fixed-coefficient droop control scheme. Nevertheless, the frequency-supporting capability of this control scheme with fixed gain is limited for different ...
