Resumen:

Wind parks based on doubly fed induction generators can provide primary frequency regulation if additional control loops are implemented-the blade pitch angle control is used for endowing variable-speed wind turbines with frequency regulation capabilities. This technique is proposed in this paper for wind turbines to provide frequency support in the Mexican power system, which is fully evaluated under the perspective of the Mexican grid code. To this end, the performance of a recently commissioned 180-MW DFIG-based wind farm in Mexico, with pitch angle control for frequency support is studied. In addition, an equivalent model of the mexican power system is assessed using credible scenarios with high wind power penetration and different demand scenarios. The impact of the wind parks is thoroughly assessed under the perspective of the Mexican grid code, identifying under which operating scenarios and wind turbine parameters, the wind parks comply with the requirements imposed by the grid code for primary frequency control. © 2019 IEEE.
