Design consideration on algorithms and control structures for photovoltaic grids

The main issue of paper consist in proposing a few algorithms and control structures for PV grids which can increase predictability and flexibility degrees with respect to specific disturbances. The starting point of our model is the division of the PV grid in subgroups of optimal dimension and pairings that offer minimal variation between the quantity of energy needed and the one prognosticated. We propose several strategies of choosing the dimension of subgroups and an algorithm for optimization. The structures obtained in this way are tested in a scenario that assumes modifications of both the set point and also the existence of a global and local perturbation. All of the structures were implemented in multiple experimental Matlab-Simulink simulators.
