Abstract EN
Photovoltaic systems have a nonlinear characteristic in which there is one optimum operating point called Maximum Power Point (MPP).
However, when PV panels are partially shaded by surrounding objects, there are several MPPs, of which one of them is Global MPP (GMPP).
Therefore, conventional Maximum Power Point Tracking (MPPT) algorithms get trapped into local MPPs.
As a result, a multitude of Global MPPT (GMPPT) algorithms have been proposed.
An outstanding GMPPT algorithm as well as the fast-tracking speed should find GMPP in complicated shading patterns where not only there are lots of MPPs, but also the peaks are close together.
Therefore, in this paper, a novel GMPPT based on firework algorithm is proposed which is able to find GMPP in complicated shading patterns with fast tracking speed.
Moreover, the firework is combined with Perturb-and-Observe (P&O) algorithm to reduce the computational effort in a way that the firework is only used to recognize GMPP; afterwards, P&O algorithm completes the tracking.
Furthermore, the variable sampling time technique, based on the system settling time, speeds up the tracking process considerably.
Finally, the proposed method is compared with previous works, simulated, and implemented on an experimental setup to prove its superiority.
