Development and application of a global magnetic field evolution model for the solar corona [PDF]

, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Transmission Expansion Planning using Binary Differential Evolution considering forecasted solar Photovoltaic generation

Energy Reports, 2023
Transmission Expansion Planning (TEP) can be essentially affected by solar Photovoltaic (PV) penetration because its generation is uncertain depending on weather and the environment at a specific time.

Is Our Understanding of Solar-Wind/Magnetosphere Coupling Satisfactory?

Frontiers in Astronomy and Space Sciences, 2021
An assessment of our physics-based understanding of solar-wind/magnetosphere coupling finds that the understanding is not complete. Solar-wind/magnetosphere coupling is foundational to magnetospheric physics and it is a key to comprehending and ...
