Abstract

In this paper, the Predictive Current Control (PCC) strategy for back-to-back (BTB) voltage source converters used in Permanent Magnet Synchronous Generator (PMSG), Wind Energy Conversion System (WECS) was explained. PCC is used to control the system, where the discrete time models of the BTB converters are used to predict the future state of control variables. Two cost functions are used to evaluate these predictions, and switching states which will minimize these cost functions will be selected and applied to generator side and grid side converter. The control requirements like Maximum Power Point Tracking (MPPT), Direct Current (DC) link voltage regulation and reactive power generation to the grid are satisfied by the PCC approach. Complete procedure for the MATLAB/Simulink implementation of predictive model, extrapolation and cost function employed in the implementation of PCC scheme are presented along with the comparison of the performance of Wind Energy Conversion System (PMSG WECS) and back-to-back (BTB) converter with conventional control technique.
