Incidence on Power System Dynamics of High Penetration of Fixed Speed and Doubly Fed Wind Energy Systems: Study of the Spanish Case

A preliminary analysis of the impact of high wind power penetration in the planning and operation of the Spanish power system is presented. The problems studied are those related to the stability of the power system. This key subject could be deeply influenced by the installation of up to 15,000 MW of wind power generation as it has been planned for the next 6 years. The analysis is based on the results of dynamic simulations. Dynamic models of the induction generator (squirrel cage and doubly fed) and models of the wind farms have been developed to make possible the simulations. From the simulation results, some conclusions and recommendations have been extracted that would contribute to the appropriate integration of the new wind generation foreseen for the Spanish power system.
