Research and application of intelligent control algorithm for multi peak MPPT for Quasi-Z-source inverters in Photovoltaic system
Technology of maximum power point tracking(MPPT)is the key technological problem for light volt generating.This paper studies a type of adaptive weight inertia variation cat swarm algorithm,which is realized by photovoltaic battery output voltage and the load voltage matching control,and achieves the maximum power output in the power system.Characteristic curves with multiple peak values present under the interference of numerous complex factors.This article expounds the algorithm solved the partial shade of multiplex mode optimization problems which is unable to realize by the traditional tracking.How to realize the maximum power point tracking is the key research for quasi-Z-source inverters in Photovoltaic system.It is proved that the feasibility of the improved algorithm proposed and the advantages of high speed and precision in tracking build mathematical model used commonly through the MATLAB/Simulink.
