This paper is about simulated annealing (SA)
algorithm used to tracking the maximum power point (MPP)
applied to photovoltaic array. The present method adjusted the
SA algorithm to variables analysed on photovoltaic systems (PV).
Therefore, the power is the objective function and it depends on
duty cycle, which is the independent variable. Initially, the SA
algorithm is at random. However, the convergence methods lead
the system to a global optimal point. Hence, the SA would avoid
the ineffective exploration on the local optimal solutions like
MPPT classic algorithms, mostly when the photovoltaic array is
under partial shading conditions. The simulations have been
done by PSIM software and the code could have been
implemented in a digital signal controller (DSC).
