Power control of variable speed wind turbines coupled with squirrel cage induction generators is difficult and suffers from some fundamental problems. If this type of wind turbines are applied to remote areas, they cannot stabilize frequency and voltage of the grid in acceptable limits. Changes in the load during one day also make this problem harder to deal with. In this paper, a system consisting...
With a view to the integration in national power system of new power plants based on renewable energy sources, such as wind energy, this paper presents the technical requirements related to the connection of the wind power plants to the main grid. Grid connected wind turbines may cause power quality problems, such as voltage variation and flicker, and therefore, the connection of wind farms requires...
Generating power of wind turbine varies in proportion to the cube of wind speed, so they cannot supply constant power and this causes frequency and voltage fluctuations. This paper presents a methodology for controlling grid frequency, hydrogen volume and terminal bus voltage. This system consists of diesel generator, wind turbine and load. Aqua electrolyzer and fuel cell are installed in order to...
