Abstract: Apparatuses, systems and methods are described for optimizing power production from power generating devices by dynamically grouping the power generators. The power generating devices may be dynamically grouped into power sources according to a Maximum Power Point of the power generators, and the power output of the grouped generators may be controlled by alternatively connecting the output of the power sources. The output power may also be optimized by dynamically grouping the power generators, so that a maximum power may be generated.

Abstract: A power system may comprise a plurality of power sources, each connected to a corresponding power regulator. The power regulators may be connected in series or in parallel, and may form a string. Each power regulator may comprise input terminals connected to the corresponding power source, output terminals, and a power converter that may be configured to convert input power from the corresponding power source to output power. The power regulator may further comprise a regulator communications module that may be configured to receive a power regulation indication relating to regulating an operational characteristic of the power regulator. The regulator controller may be configured to instruct the power converter to increase or decrease the regulator operational characteristic based on the power regulation indication, and based on power production characteristics of the power regulator.

Abstract: Systems and/or methods for mapping power device in a string of serially connected power devices are disclosed herein. A power source may apply a source voltage to a first end of the string. A power system controller coupled to the two ends of the string may send a first signal to the power devices in the string. The power devices in the string, responsive to receiving the first signal, may measure electrical characteristics of the power devices, where the measured electrical characteristics may indicate the parasitic leakage of the power devices. The power devices may send second signals to the power system controller to report the measured electrical characteristics. The power system controller may determine the mapping of the power devices in the string based on the second signals.
