Maximum power point tracking is an method to derive maximum amount of power from PV array irrespective of its atmospheric and load conditions. There is only singular point on the PV graph where we can obtain the maximum power more popularly known as MPP. Basic conventional methods namely Perturb & Observe (P&O), Incremental Conductance method ( INC ) & Fractional open circuit voltage have a very elementary design in obtaining the maximum power which are unsuitable to track the maximum power under partial shade conditions & rapid atmospheric change conditions. Hence to overcome the above situations MPPT methods based on partial shade conditions are illustrated in these Paper. In addition to these the advancement made in conventional methods regarding the step size is also proposed in these paper. Advanced MPPT methods based on Artificial Intelligence which are bio inspired algorithms are presented.
