Dynamic modelling of wind farms in transmission networks

Penetration of wind energy in power systems in Europe is steadily increasing. Because of the limited extension of the power system, in Ireland this process is particularly challenging. In order to facilitate the anticipated capacity growth, the TSO has to evaluate the anticipated impact on power system stability and security of supply by simulations. Modelling of wind farms in power systems, however, is a young and dynamically evolving discipline. The paper describes key aspects for specification and application of wind farm models. Based on a review of state of the art, conclusions are drawn regarding required progress. This progress essentially is related to adequate specification of model requirements and practical validation of model results.
