A power distribution system for data center systems (and corresponding method) feeds DC power directly to a first AC-DC power supply of a computer system in the data center system and feeds AC power to a second AC-DC power supply of the computer system to efficiently and reliably provide an uninterruptible supply of power to the computer system. The power distribution system includes an energy storage unit for supplying the DC power, a charger for charging the energy storage unit, and an inverter through which the energy storage unit provides energy to an electrical substation of an electrical grid. The charger is configured to receive energy from a renewable energy source and the electrical substation. The inverter may also be configured to receive renewable energy from the renewable energy source and supply that energy to the electrical substation. An uninterruptible power supply may be coupled between the electrical substation and the AC power feed. The power distribution system further includes a monitor for monitoring the flow of current to and/or from the electrical substation, a communications interface for receiving messages or requests from a utility company associated with the electrical substation, and a controller for controlling the components of the power distribution system based on requests from the utility company and the information gathered by the monitor. |
