Research on MPPT Algorithm for PV Array Under Partially Shaded Conditions
Conventional maximum power pointing tracking(mppt) methods are effective under uniform solar irradiance.However,PV models can be partially shaded under some conditions,and the output-current curve will have several local maximum power points,and that makes conventional algorithms fail to track.Analyses I-V and P-V characteristics of the PV modules under partially shaded conditions,and proposes a novel MPPT method capable of tracking real MPPT.
