Comparison of wind energy integration into a 110kV and a 380kV transmission system - Impact on power quality of MV and LV networks

The amount of electrical energy produced by wind farms is constantly increasing. Nowadays detailed analyses considering the impact of wind energy integration on the transmission system are required. Therefore several wind impact studies have been carried out. The conclusions of these studies are related to different aspects of wind power, such as it's fluctuating nature, distributed location of wind farms, generator technologies, generator control etc. The goal of this study is to compare the power quality behavior of the MV and LV network in case of integration of different amounts of wind energy at different locations of the 110 kV and 380 kV transmission systems.
