Abstract:
In this article novel fast sweeping
method is proposed as MPPT for PV fed water
pumping system. Solar photovoltaic (PV) array
which is exposed to the uniform solar irradiance
shows the non-linear P-V characteristic. Though,
the P-V characteristic becomes further complex
with numerous maximum power points (MPP)
when the array is functioned in partially shading
condition. PSC results hotspots, power loss and
reduces the reliability of the solar power
generation system. Furthermore PV characteristic
curves of solar panel array reveal several peaks.
The main disadvantages of traditional MPPT
methods are that they are unable to track global
peak under non-uniform irradiance/insolation.
Under this condition traditional MPPT methods
frequently are unsuccessful to provide optimum
MPP. In this paper novel Fast sweeping method is
proposed as MPPT to track global MPPT. The
performance of proposed MPPT is compared with
existing intelligent controllers such as Fuzzy logic
controller, artificial neural network controller and
adaptive Neuro Fuzzy inference system based
MPPT in a partial shading condition. Entire
system is analysed using Matlab. Experimental
analysis is done to validate the simulation.
