US Patent 9218035 Renewable energy control systems and methods

Various examples are provided for renewable energy control. In one example, among others, a system includes a PV source, a multi-core processor load, and a solar power manager configured to adjust an operating point of the PV source about a maximum power point by dynamically adjusting a transfer ratio and a load level. In another example, a method includes sensing an output current supplied to a multi-core processor load by a power converter at a first transfer ratio, sensing another output current supplied at a second transfer ratio, and determining an operating point of the PV source with respect to a maximum power point based upon the output currents. In another example, a system includes a power manager configured to switch servers between a renewable energy supply and a utility energy supply based at least in part upon a budget level and the load power consumption.
