Design and implementation of MPPT solar system based on the enhanced P&O algorithm using Labview

Maximum Power Point Tracking algorithms (MPPT) are used to track maximum power, a DC-DC Boost converter is used to obtain the impedance matching between the PV array and the load. Although a huge number of approaches have been proposed in literature, the methods based on the perturb and observe (P&O) technique are the most widely employed in commercial products. The reason lies in the fact that P&O can be implemented in cheap digital devices by ensuring high robustness and a good MPPT efficiency. This paper aims to presents the design and development of a photovoltaic system based on the enhanced P&O algorithm that allows to improve efficiency, stability and accuracy of solar systems. The effectiveness of the proposed solar regulator system is verified by the simulation by PowerSim simulator and experimental results under our developed system using two MPPT algorithms, classical P&O and a new enhanced P&O algorithm.
