چکیده
|
In photovoltaic (pv) system,maximum power tracking (mppt) is crucial to improve the system performance. irradiance and temperature are the two important parameters that affect mppt. the conventional perturbation and observation (p&o) based mppt algorithm does not accurately track the pv maximum power point. therefore,this paper presents an improved p&o algorithm (im-p&o) based on variable perturbation. the idea behind the im-p&o algorithm is to produce variable step changes in the reference current/voltage for fast tracking of the pv maximum power point. the im-p&o based mppt is designed for the 25 solartifstf-120p6 pv panels,with a capacity of 3 kw peak. a complete pv system is modeled using the matlab/simulink. simulation results showed that the im-p&o based mppt achieved faster and accurate performance compared with the conventional p&o algorithm. © 2016 penerbit utm press. all rights reserved.
