Abstract

Photovoltaic (PV) systems used in moving equipment are frequently affected by the continuously changing operating environments. In general, the series connect (SC) configuration often have more extremes and can be neglected the energy of shaded PV panels under this condition. This is the cause of the unstable output voltage, making it difficult to access the maximum power point tracking (MPPT) and energy loss. This article introduces a solution to overcome the above disadvantages with a Series - Parallel connect (S-PC) configuration of PV arrays, which can significantly reduce the SC junction to simplify the characteristic curves. The proposed link combined with a buck-converter circuit and a modified perturbation and observation (M-P&O) algorithm has shown effective MPPT in all experimental operating conditions. The simulation results from the proposed solution are compared with the traditional P&O algorithm under the same operating conditions, pointed that it can be widely applied in displacement devices using PV systems.
