This article presents the control algorithms that allow a variable speed wind turbine generator based on an asynchronous wound rotor machine, to contribute to the control of the frequency and voltage amplitude of the grid. Two different high level control techniques are proposed as solutions to control the frequency of the electrical grid by means of a variable wind speed turbine. It is also proposed, an electrical grid’s voltage amplitude control by means of the asynchronous generator of the variable wind speed turbine. Experimental results in a platform rig are presented validating satisfactorily proposed techniques in order to contribute to the control of the electrical grid.
