Power Supply System Including Alternative Sources-DC Power Management

Abstract

A power supply system comprises multiple power consumption units, a DC power distribution unit, a control unit and a centralized DC power storage unit. The DC power may be generated from local alternative power sources in the consumption units. The DC power may also be generated from alternative power sources remotely located to the consumption units. The control unit may allocate generated DC power to the consumption units based upon predetermined rules including: 1) minimizing power loss during the transmission; 2) delivering to the units that offer better prices; and 3) delivering to the units that require DC power in exceeding of a minimum amount. The control unit may decide to either store surplus DC power in the centralized storage unit or convert the surplus DC power into AC form by a centralized inverter.
