Research on Photovoltaic System with Supper Capacitor Based on Improved MPPT Algorithm

Abstract:

The output power of photovoltaic (PV) cells would crucially change due to the intensity of solar irradiation and the environment temperature. For the sake of achieving more efficiency of solar power system, the Maximum Power Point Tracking (MPPT) is highly demanded. This paper focuses on analyzing the implemental principle of MPPT with an improved incremental method under the standard conditions. An algorithm is applied to PV system where supper capacitor is chose as energy storage element. Finally, an experimental prototype was designed to verify the validity of the improved increment method. It provides the contrast experiment waveforms between the improved increment method and increment conductance method. The result of experimental shows the effectiveness of the algorithm.
