Abstract

Wind energy system integration can lead to adverse effects on modern electric grid so it is imperative to assess their dynamic performance before actual plant startup. Transmission system operators all over the world stress the need for a proper wind turbine generator model for dynamic performance as well as ancillary service assessments. Due to the bulk power system assessment requirements, development of suitable generic modeling has gained high priority. Generic modeling of type 4 full converter wind turbine generator system for application in frequency ancillary service investigations under varying wind speed and varying reference power has been presented in this study. Prevalent generic model, manufacturer specific proprietary generic model along with detailed wind turbine model with synchronous generator is also provided to highlight various modelling framework difference. Descriptions of individual sub models of proposed generic model are presented in detail and performance results are compared and validated with GE’s proprietary generic model and detailed WTG model by means of simulations in the MATLAB® Power System Block set.
