Abstract
The present disclosure provides systems and methods for shaping the load of a building for more efficient sizing and/or economics of an energy storage and/or microgrid system. Shaping the load of a building can include identifying a plurality of core hours of a time period increasing a load of the building, a plurality of different increase instances, by interfacing with a BAS and an ESS during the plurality of core hours, and decreasing the load of the building, a plurality of different decrease instances, by interfacing with the BAS and the ESS during the plurality of core hours, wherein each increase instance from the plurality of different increase instances of the load profile is followed by a decrease instance from the plurality of decrease instances of the load profile.
Claims20
A system to manage energy utilization, comprising one or more processors and memory to:
- identify a load profile comprising a plurality of first peaks corresponding to increase instances at which a load increases and a plurality of decrease instances at which the load decreases;
- select a shape of each of a plurality of second peaks with a function based on a discharge potential of an energy storage system (“ESS”) from a single peak of the plurality of first peaks in the load profile, a discharge potential of the ESS from the plurality of second peaks, and a recharge potential of the ESS associated with generation of the plurality of second peaks;
- decrease the load to transition the single peak of the plurality of first peaks in the load profile to the plurality of second peaks with the selected shape and at least one valley in one or more portions of a period of time associated with the single peak, the plurality of second peaks narrower than the plurality of first peaks at a point of the load profile at which the ESS can initiate a discharge or a charge of a battery;
- and
- discharge the battery of the ESS to shave off at least one peak of the plurality of second peaks to reduce energy utilization corresponding to the at least one peak of the plurality of second peaks.
A method of managing energy utilization, comprising:
- identifying, by one or more processors, a load profile comprising a plurality of first peaks corresponding to increase instances at which a load increases and a plurality of decrease instances at which the load decreases;
- selecting, by the one or more processors, a shape of each of a plurality of second peaks with a function based on a discharge potential of an energy storage system (“ESS”) from a single peak of the plurality of first peaks in the load profile, a discharge potential of the ESS from the plurality of second peaks, and a recharge potential of the ESS associated with generation of the plurality of second peaks;
- decreasing, by the one or more processors, the load to transition the single peak of the plurality of first peaks in the load profile to the plurality of second peaks with the selected shape and at least one valley in one or more portions of a period of time associated with the single peak, the plurality of second peaks narrower than the plurality of first peaks at a point of the load profile at which the ESS can initiate a discharge or a charge of a battery;
- and
- discharging the battery of the ESS to shave off at least one peak of the plurality of second peaks to reduce energy utilization corresponding to the at least one peak of the plurality of second peaks.
