This article presents a model prescient control (MPC) system for variable speed wind energy transformation framework (VS_WECS) based lasting magnet coordinated generator (PMSG). The prescient control is applied for ideal activity of a PMSG wind turbine (WT). The PMSG is attached to the utility framework through a three-stage consecutive (BTB) converter. The greatest force accessible from the WECS is collected by applying the control calculation to the machine side converter (MSC). The dc-interface voltage guideline is accomplished utilizing the framework side converter (GSC). A model of straightforwardly determined PMSG based variable-speed WECS is created and imitated utilizing MATLAB/SIMULINK climate. The MPC gives great unique execution under wide wind speed variety. The viability of the proposed control approach is approved through broad reenactment results. The THD (total harmonics distortion) of the grid current is maintained under the limit of an IEEE-519 standard.

Energy Conversion System

A nonlinear control of a PV Energy Conversion System (PVECS) with energy storage system and maximum power extraction is presented. The control strategy is designed in two steps. Firstly, a MPPT algorithm is designed to tracking the maximum power point in variable irradiations, battery state of charge (SOC) and load changes. Then, thanks to its many advantages such as simplicity against parameter uncertainties, a Sliding Mode Control approach (SMC) is applied to control the standalone PV energy conversion system. Finally, the performances of MPPT techniques and SMC controller in the closed loop are checked using the MATLAB/SIMULINK.
