摘要:
The output characteristic of a photovoltaic (PV) module is nonlinear and changes with solar irradiance and cell's temperature. Thus, its maximum power point (MPP) is not constant. The use of Maximum Power Point Tracking (MPPT) techniques is primordial. This paper highlights two MPPT techniques: the perturb and observe (P&O) and the sliding mode control (SMC), applied to a standalone PV system under varying climatic conditions. Simulation results show that SMC provides good performance under the climatic changes in term of stability and robustness to irradiance and temperature variations compared to P&O.
