Overview of recent grid codes for wind power integration

Abstract

As wind power penetration level increases, power system operators are challenged by the penetration impacts to maintain reliability and stability of power system. Therefore, grid codes are being published and continuously updated by transmission system operators of the countries. In this paper, recent grid codes, which are prepared specially for the large wind power plants, are analyzed and compared. Also, harmonization of different grid codes in a common manner and future trends are assessed.
