Abstract
A distributed direct current power system including an inverter to invert DC to alternating current (AC), a plurality of photovoltaic (PV) strings, and a plurality of maximum power point tracking (MPPT) converters coupled between the plurality of photovoltaic (PV) strings, respectively, and the central inverter, the plurality of MPPT converters configured to maximize solar power production by the plurality of PV strings and minimize mismatch between the plurality of PV strings. The system also including a plurality of batteries, a plurality of DC-DC battery converters (DCBC) coupled to the plurality of batteries and configured to manage charge and discharge of the plurality of batteries, enable interconnection of the plurality of PV strings and the plurality of batteries, and supply a constant medium DC voltage to the central inverter, and a hydrogen generation system in electrical communication with the inverter, the photovoltaic strings, or the batteries.
