Changing Face of the Extrasolar Giant Planet, HD 209458b [PDF]
, 2002 High-resolution atmospheric flow simulations of the tidally-locked extrasolar giant planet, HD 209458b, show large-scale spatio-temporal variability. This is in contrast to the simple, permanent day/night (i.e., hot/cold) picture.

An improved grid-connected pre-synchronization method for photovoltaic micro-grid
Journal of Physics: Conference Series, 2020 Abstract Due to the obvious steady-state error that traditional grid-connected pre-synchronization regulation, current shock may occur when photovoltaic micro-grid is connected to the grid. To solve this problem, an improved pre-synchronization method with higher steady-state adjustment accuracy is designed by using the brain emotion ...

PMSG Wind turbine grid-connected pre-synchronization technology based on virtual impedance
Journal of Physics: Conference Series, 2021 Abstract With the integration of large-scale wind power, the inertia of the whole grid system is reduced. Therefore, virtual synchronous machine (VSG) technology has become a new strategy for wind power integration. In view of the fact that the VSG grid connected control of permanent magnet direct drive wind turbine does not consider the
