Abstract
The penetration of wind energy into small, lightly interconnected power systems, as in Ireland, is increasing. It is therefore important to study how wind farms will interact dynamically with conventional generators and loads. For the future, we need to asses the impact this will have on the stability of the whole system. To investigate this interaction, dynamic simulation studies of the system, with the inclusion of wind turbine generators (WTGs), are important. This requires these generators to be represented in power-system simulation studies to at least the same detail as conventional machines. This paper analyses the dynamic models for WTGs available during 2003 to the Irish Transmission system operator, ESB National Grid. The paper focuses on the modelling of Doubly-Fed Induction Generators (DFIGs). A comparison of the models was carried out and the main conclusions drawn are discussed.
