Abstract (en)
[origin: WO2009140543A2] A system for integrating local maximum power point tracking (MPPT) into an energy generating system (10) having centralized MPPT is provided. The system (10) includes a system control loop (16,32,22) and a plurality of local control loops (12,14). The system control loop (16,32,22) comprises a system operating frequency, and each local control loop (12,14) comprises a corresponding local operating frequency. Each of the local operating frequencies is spaced apart from the system operating frequency by at least a predefined distance. For a particular embodiment, a settling time corresponding to the local operating frequency of each local control loop (12,14) is at least five times faster than a time constant corresponding to the system operating frequency.
