In this paper, the voltage control performance of typical wind farm grid connection schemes such as AC link type and AC-DC-AC link type with the wind farm introduction place as a parameter to clarify the reasonable grid connection.Abstract:
A lot of wind farms has been promoted from the viewpoint of the global environmental problem in Japan. These are introduced at the end of transmission line at middle voltage system because the wind blows considerably only in the limited place. Therefore, it is necessary to examine how one wind farm can be introduced to one site in power system from the viewpoint of the voltage and power flow. This paper shows the voltage control performance of typical wind farm grid connection schemes such as AC link type and AC-DC-AC link type with the wind farm introduction place as a parameter to clarify the reasonable grid connectionread more

Flicker contribution from wind turbine installations
TL;DR: In this article, the influence of wind speed, turbulence intensity, grid voltage quality, grid types, and number of turbines operating in the same group is measured and analyzed, and it is found that the voltage quality of the grid to which the turbines are connected strongly influences the flicker emission of the turbines.
