Abstract

A method for selecting between centralized and distributed maximum power point tracking in an energy generating system (500) is provided. The energy generating system (500) includes a plurality of energy generating devices (502), each of which is coupled to a corresponding local converter (504). Each local converter (504) includes a local controller (508) for the corresponding energy generating device (502). The method includes determining whether the energy generating devices (502) are operating under quasi-ideal conditions. The energy generating system (500) is placed in a centralized maximum power point tracking (CMPPT) mode when the energy generating devices (502) are operating under quasi-ideal conditions and is placed in a distributed maximum power point tracking (DMPPT) mode when the energy generating devices (502) are not operating under quasi-ideal conditions.
