The aspect of power quality in a wind generation: Overview

Abstract

Because of fossil fuels cost is high and environmental issues pushes to renewable energy sources to be used significantly. One of these wind energy got a lot of investments. It is difficult for good power quality due to the behavior of wind turbine speed. It effects on the power and voltage of the component that connect with the wind turbine. A new technique must be developed and new control must be used to control the fluctuations and improve wind power performance. Also using possible excitation induction generators for safety issues. More over the smoothening wind power variation done by using some energy storage technologies. Using a static compensator for the harmonic current injection and reactive power compensation. Besides of improving power quality of wind turbine also the fault tolerance. Dynamic voltage restorer used to treat the reactive power compensation connected to a wind turbine.
