Renewable energy control systems and methods
First Claim
1. A system, comprising:
- at least one cluster including a plurality of servers; and
a power manager configured to switch at least a portion of the plurality of servers between a renewable energy supply (RES) and a utility energy supply based at least in part upon a budget level corresponding to an amount of power available from the RES and a load power consumption of the at least one cluster, where the power manager comprises a central switch controller configured to switch the at least a portion of the plurality of servers based upon a switch assignment determined by a switch scheduler based at least in part upon switching history and load history.

Abstract
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.

10. A system, comprising:
-
at least one cluster including a plurality of servers; and a power manager configured to switch at least a portion of the plurality of servers between a renewable energy supply (RES) and a utility energy supply based at least in part upon a budget level corresponding to an amount of power available from the RES and a load power consumption of the at least one cluster, where the power manager comprises a central switch controller configured to switch the at least a portion of the plurality of servers based upon a switch assignment determined by a switch scheduler that is configured to allocate switch operations of the switch assignment using a least recently used (LRU) scheme based at least in part upon a switching frequency of server loads. - View Dependent Claims (11, 12)

13. A method, comprising:
-
determining a budget level corresponding to an amount of power available from a renewable energy supply (RES); and switching server loads of at least one cluster of servers between the RES and a utility energy supply based at least in part the budget level and a load power consumption of the at least one cluster, where switch operations are allocated using a least recently used (LRU) scheme based at least in part upon a switching frequency of the server loads. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
