Abstract :
The output power of photovoltaic (PV) module is the function of module temperature and solar insolation, so it is necessary to track maximum power point (MPP) all the time. Among of presented MPPT methods, perturbation and observation (P&O) method has drawn more attractions due to its simple and high efficiency. However the PV module works around MPP, the output power of PV module will oscillate around it. The characteristics of PV modulewhich are discussed in detail, show different features of MPP sides is the reason of power oscillation. A novel asymmetric fuzzy control method, which adjusts the perturbation step according to the PV module work, is presented to reduce the power oscillation. Experimental results show the presented method can track MPP rapidly under solar insolation changing and reduce remarkable power oscillation.
