Campus energy manager

摘要

An energy management system serves an arbitrary collection of loads via interfacing with related field devices and external information sources and responding to events including pricing events, demand response events, and carbon reduction events by managing the loads and local generation.

1. A campus energy management method comprising the steps of:
providing a campus electric power infrastructure including a campus electric power distribution system; providing an energy manager for managing electrical loads interconnected with the campus electric power infrastructure; providing field devices interfacing with campus loads and local generating resources; providing field devices sensing load related environmental variables; providing energy manager interface modules including bidirectional interface modules for translating field device data into a common format acceptable to the energy manager; an energy manager processor receiving information from field devices via the interface modules; and, the energy manager processor issuing commands to field devices via the interface modules; determining from a plurality of operating modes a particular operating mode; in a demand response operating mode with a requested load reduction RLR, managing by evaluating a potential for building load reduction BLR, if BLR>=RLR then issuing building load reduction command(s), if RLR>BLR then determining if RLR>dispatchable local generation DLG, and if RLR>BLR and if RLR>DLG then issuing building load reduction command(s) and dispatching dispatchable local generation; in a carbon reduction operating mode with a target carbon reduction TCR, managing by determining CO2 reduction from potential load reduction LCR, and if LCRM$ and where this inequality is expected to hold for a time period exceeding a selected minimum local renewable generation run time period.
