MPPT technique for PV system under fast-varying solar irradiation

This article presents a simpler fast-converging MPPT technique, which excludes the extra control loop and intermittent disconnection. In the proposed algorithm, the relationship between the load line and the IV curve is used with trigonometry rule to obtain the fast response. Results of the simulation and experiment using single ended primary-inductor converter showed that the response of the proposed algorithm is four times faster than the conventional incremental conductance algorithm during the load and solar Irradiation variation. Consequently, the proposed algorithm has higher efficiency.




The  frequently referred to as MPPT, is an electronic system that operates the Photovoltaic (PV) modules in a manner that allows the modules to produce all the power they are capable of. MPPT is not a mechanical tracking system
