Research Abstract

This paper proposes a method for modeling and simulation of photovoltaic arrays. The method is used to obtain the parameters of the array model using its datasheet information. To reduce computational time, the input parameters are reduced to four and the values of shunt resistance Rp and series resistance Rs are estimated by simulated annealing optimization method.
Then we draw I-V and P-V curves at different irradiance levels.
Lowcomplexityanalogue MPPT circuit can be developed by
using two voltage approximation lines (VALs) that approximate
the maximum power point (MPP) locus.In this paper, a fast and
low-cost analog MPPT method for low power PVsystems is
proposed.The Simulation results coincide with experimental
results at different PV systems to validate the powerful of the
proposed method.
