Systems and methods for load distribution, where a method can include: establishing an interface with a controlling architecture of an electric power distribution system, the electric power distribution system in communication with a set of outlets of utility-facing devices providing access to the electric power distribution system; returning a demand assessment from a demand model characterizing anticipated demand upon the one or more portions of the electric power distribution associated with the set of outlets, the set of outlets positioned at a set of sites; and executing an action for adjustment of load distribution throughout the set of sites, through the controlling architecture, based upon the demand assessment. The inventions can be used to achieve carbon emission goals by incentivizing better use of limited energy resources.
COGNITIVE FRAMEWORK FOR IMPROVING RESPONSIVITY IN DEMAND RESPONSE PROGRAMS
Methods, computer program products, and systems are presented. The methods include, for instance: obtaining historical data of demand response programs and demand response agreements respective to each of the users regarding a subject energy. Training dataset for a DR user pooling model includes attributes of the demand response data collected that are relevant to responsivities of the demand response programs. The DR user pooling model is trained by the training dataset by machine learning. A DR user pool is identified amongst users of the demand response program by the DR user pooling model. Users in the DR user pool respond to demands as a group and the DR user pool is adjusted to improve responsivities of the demand response programs.
BEHIND-THE-METER RESOURCE MANAGEMENT SYSTEM
A method and a system for managing power resources. One or more measurements received from one or more sensors communicatively coupled to at least one processor are processed. The sensors monitor and measure at least one of: one or more operational parameters associated with operation of at least one equipment, one or more external parameters associated with an environment of the equipment, and one or more power parameters associated with a power consumption by the equipment.

HIERARCHICAL METHOD FOR PREDICTION OF LOADS WITH HIGH VARIANCE
A method and system are provided for improving predictions of electrical power usage. In the method and system, load and/or environmental data is classified into data sets that correspond to different modes of operation of an electrical load.
