Contribution of dispersed power generation to power quality - Certification of advanced electrical characteristics based on validated WEC models and simulation of wind farms

This paper describes the most recent German regulation on the integration of dispersed power generation into the medium and high voltage grid in terms of the latest grid codes. A special consideration is given to the advanced requirement on frequency control and dynamic voltage support. An overview on the status quo of certification regulations and implementation approaches in selected countries both on single WEC types and on wind farms is provided. Furthermore, the model validation and subsequent certification procedure FGH Certification Office has developed and applied to first wind farm certifications will be presented. A focus will be given to the validation of the WEC model and the simulation of the wind farm´s reactive current injection under fault conditions.
