The global wind power capacity is on a constant rise. Many countries are moving towards renewable energy sources. Wind energy accounts for the biggest renewable energy resource in Europe. Despite all the benefits, wind energy tends to weaken the grid stability. One reason for this is the fact that most wind turbine generators are not directly coupled to the grid and do not provide ancillary services, such as primary frequency control, due to the lack of rotating inertia. This paper presents detailed models of a wind turbine with a permanent magnet synchronous generator (PMSG). This model is used to test the feasibility of providing ancillary services by performing the pre-qualification test for primary frequency control, as established by the Belgian Transmission System Operator (TSO). These tests are conducted under 4 different wind profiles, each having a different level of turbulence.
