Abstract :

This paper presents a specific wind energy conversion system based on doubly fed induction generator for Voltage fluctuation (sags and swells), interruptions of output power, total harmonic distortion and many other different types of distortion are the main issue of the wind based power system and these power quality problem. Now days, wind power technology has been growing widely. With the incorporation of Wind turbines together with the electrical grid, it is necessary for the system operators to know the behaviour of wind turbine under all the operating Many areas of interest in the power system such as calculation of wind speed, modelling, control and stability analysis of the wind system connected with electric grids are of importance in the modern power system. The problem related to the various effects of wind energy when integrated with the power system on the stability of the system is gaining more interest of researchers because of increasing of its penetration level. In this paper literature review on various effects of wind power incorporation on the power system stability and several methods for the enhancement of the small signal stability of wind system integrated with electric grid is presented.
