ABSTRACT:
A method for selecting between centralized and distributed maximum power point tracking in an energy generating system is provided. The energy generating system includes a plurality of energy generating devices, each of which is coupled to a corresponding local converter that includes a local controller. The method includes determining whether there is at least a threshold amount of mismatch between operating characteristics of the energy generating devices. The energy generating system is placed in a centralized maximum power point tracking (CMPPT) mode when there is not at least the threshold amount of mismatch and is placed in a distributed maximum power point tracking (DMPPT) mode when there is at least the threshold amount of mismatch.
