Novel predictive voltage controlled UPS inverter for an improved stand-alone wind turbine system

In this paper, a novel PI-based predictive voltage controller with a feed-forward voltage compensator is developed for a single phase Uninterruptible Power Supply (UPS) inverter of a stand-alone wind turbine system in order to obtain high system performance with both linear loads and nonlinear loads. Space vector pulse width modulation (SVPWM) and pulse based dead-time compensation are introduced in this paper to implement the control technique. Simulation and experimental results based on a 1 kVA single phase inverter prototype are included to show the effectiveness and the performance of this proposed controller.
