Geomagnetic storms driven by ICME- and CIR-dominated solar wind. [PDF]

, 2006
The interaction of the solar wind and the Earth's magnetosphere is complex and the phenomenology of the interaction is very different for solar wind dominated by interplanetary coronal mass ejections (ICMEs) compared to solar wind dominated by corotating

Design and implementation of a general batch simulation tool of SOWFA and its application in training a single-turbine surrogate

Energy Reports, 2023
Simulator fOr Wind Farm Applications (SOWFA) is a powerful wind farm simulation tool. It is widely used in wake effect research. However, the integration between AI and SOWFA is weak. Without AI, it is difficult for us to fully use SOWFA.

Solar and Stellar Winds [PDF]

Highlights of Astronomy, 1989
AbstractThis review discusses winds from stars with hot outer atmospheres, stars with coronae similar to the sun. It illustrates how solar observations can be used to test a theoretical model for solar-stellar winds, and thereby provide some insights concerning applications to studying winds from stars other than the sun.

Virtual composite impedance circulating current suppression strategy with adaptive adjustment capability

IET Generation, Transmission & Distribution, 2023
In the process of accessing distributed power sources in microgrid, there will be serious coupling between active power and reactive power, which will lead to significant changes in the inverter outlet voltage and impedance and increase the circulating ...

Research on participation of flywheel energy storage in wind farm frequency regulation control

Zhejiang dianli, 2022
In view of a whole series of problems such as the reduction of system inertia， the increase of frequency fluctuation， and the deterioration of power quality caused by large-scale wind power integration， a flywheel with high power density is designed for ...

Statistics of counter-streaming solar wind suprathermal electrons at solar minimum : STEREO observations [PDF]

, 2010
Previous work has shown that solar wind suprathermal electrons can display a number of features in terms of their anisotropy. Of importance is the occurrence of counter-streaming electron patterns, i.e., with "beams" both parallel and anti-parallel to ...

Solar-Wind Structure [PDF]

, 2020
Abstract The hot solar atmosphere continually expands out into space to form the solar wind, which drags with it the Sun’s magnetic field. This creates a cavity in the interstellar medium, extending far past the outer planets, within which the solar magnetic-field dominates.

Introduction to special issue on high speed solar wind streams and geospace interactions (HSS-GI) [PDF]

, 2009
This special issue of the Journal of Atmospheric and Solar-Terrestrial Physics is devoted to research into high speed solar wind streams (HSSs) and their effects on the region of near-Earth space commonly known as ‘geospace’.

Solar wind dependence of ion parameters in the earth's magnetospheric region calculated from CLUSTER observations [PDF]

, 2008
Moments calculated from the ion distributions (~0–40 keV) measured by the Cluster Ion Spectrometry (CIS) instrument are combined with data from the Cluster Flux Gate Magnetometer (FGM) instrument and used to characterise the bulk properties of the plasma
