Experimental Assessment of Perturb & Observe, Incremental Conductance and Hill Climbing MPPTs for Photovoltaic Systems
Résumé
This paper presents a simulation and hardware implementation of maximum power point tracking (MPPTs) algorithms. The investigated algorithms are: perturb and observe (P&O), Incremental conductance (InCond) and Hill climbing (HC). Firstly, the algorithms have been simulated and tested under Matlab/Simulink environment. Subsequently, the simulated algorithms have been verified experimentally at the MIS Laboratory of Picardie Jules Verne, University, (France). All steps to implement the controllers into the dSPACE are presented in detail, as well as the development hardware. The experimental test was done under a cloudy sky (solar irradiance = 100 W/m2, air temperature 6 = degrees). The obtained simulation and experimental results proved an acceptable performance of 0.8, 0.83 and 0.85 for P&O, InCond and HC respectively. A slow convergence time is observed for all examined algorithms, particularly at low solar irradiation level. \textcopyright Springer Nature Singapore Pte Ltd. 2021.
