The purpose of the present paper is solving the next fundamental problems related to the control of the wind systems: -establishing the generator optimal speed for maximum power extraction; -establishing the generator load, based on the measured wind speeds and the variation of rotating masses kinetic energies; -delivering constant power to the grid, for long interval of time, using storing devices for overtaking the power fluctuations.

This paper is focused on control solutions for a single-phase inverter for Distributed Generation (DG) systems requiring power quality features as harmonic and reactive power compensation for grid-connected operation. Based on these characteristics, a new current reference generator based on Sinusoidal Signal integrator (SSI) and Instantaneous Reactive Power (IRP) is proposed. Simulation and experimental results have been obtained from the proposed scheme implemented along with the repetitive current control.I.
