Abstract

The fixed zone perturb and observe (FZPO) maximum power point tracking (MPPT) divides the photovoltaic (PV) curve with the boundary voltages into multiple zones at different irradiance levels. This MPPT demanding has low cost and simple controller as it is easy to implement without any additional sensors. FZPO improves the steady state efficiency of the system compared to conventional perturb and observe (P&O) technique. The zone boundaries are set based on linear equations that reduces the system’s complexity and also provides efficient tracking at varying irradiance conditions. Governments all over the world have been devoting enormous resources to improving air quality in order to combat the alarming problem of air pollution. So, a focus towards electrical vehicle (EV) is increasing and it is necessary to integrate renewable sources like PV systems to it. In this paper the analysis of EV system is performer with the PV system and it is compared with FZPO to conventional P&O MPPT. The PV system based on FZPO MPPT is shown fast transient performance at varying temperature and irradiance conditions from 300 to 1000 W/m². The overall EV system performance is verified in the various aspects: - MATLAB/Simulink environment.
