This paper presents a methodology to evaluate the contribution of wind farms (WFs) to the short-circuit level of high-voltage substations. The method relies on simplified equivalent WF models suitable for integration in commercial network-analysis software platforms. The developed WF models are especially suitable for integration in PSS/E and they can be incorporated in models of large power systems. The methodology can be applied to all kinds of WFs regardless of the type of the wind turbines used. Finally, the proposed models are verified through detailed simulations and a case study concerning short-circuit level calculation at all 150-kV and 400-kV buses of the Greek power system is presented. The relevant results are presented and general conclusions are extracted.
