TLDR
A new model of photovoltaic fields is introduced that allows the simulation of a PV generator whose subsections, e.g. cells, groups of cells, panels or group of panels, work under different solar irradiation values and/or at different temperatures.About:

Maximum Power Point Tracking Scheme for PV Systems Operating Under Partially Shaded Conditions
Hiren H. Patel,Vivek Agarwal +1 more
TL;DR: A novel algorithm to track the global power peak under partially shaded conditions and a feedforward control scheme for operating the DC-DC converter is proposed, which uses the reference voltage information from the tracking algorithm to shift the operation toward the MPP.

On the Perturb-and-Observe and Incremental Conductance MPPT Methods for PV Systems
TL;DR: A detailed analysis of the two most well-known hill-climbing maximum power point tracking algorithms: the perturb-and-observe (P&O) and incremental conductance (INC) reveals that there is no difference between the two.
