Application and Comparison of Two Intelligent Control Algorithms on Grid-connected Wind Turbine for Maximum Power Point Tracking

In this paper, two algorithms Fuzzy control and Perturbation and observation (p &O) for maximum power tracking has been used on wind turbine with permanent magnet synchronous generator (PMSG). PMSG is connected to the grid by a voltage source inverter system. Permanent magnet synchronous generator wind turbine system can compensate the reactive power and inject the maximum active power of wind turbine into the grid. The control algorithm is based on the theory of instantaneous reactive power and switching inverter is based on adaptive hysteresis cycle until Variable switching frequency problem of fixed-band hysteresis cycle has been resolved and has the ability to produce a constant switching frequency. Transient and steady state response of the system under different wind speeds have been studied and the simulation results on MATLAB software is discussed in the article.
