System for demand response dispatch employing weather induced facility energy consumption characterizations

A system for dispatching buildings participating in a demand response program event, the system comprising:

• a building lag optimizer circuit, configured to determine an energy lag for a building, said building lag optimizer circuit comprising:
• a thermal response processor, configured to generate a plurality of energy use data sets for said building, each of said plurality of energy use data sets comprising energy consumption values along with corresponding time and outside temperature values, wherein said corresponding time values comprise 15-minute values, and wherein said energy consumption values within said each of said plurality of energy use data sets are shifted by one of a plurality of lag values relative to said corresponding time and outside temperature values, and wherein each of said plurality of lag values is different from other ones of said plurality of lag values, and wherein said plurality of lag values indicates shifts of said energy consumption values to different time and outside temperature values;
• and
• a regression engine circuit, coupled to said thermal response processor, configured to receive said plurality of energy use data sets, and configured to perform a regression analysis on said each of said plurality of energy use data sets to yield corresponding regression parameters and a corresponding residual;
• wherein said thermal response processor determines a least valued residual from all residuals yielded by said regression engine circuit, said least valued residual indicating said energy lag for said building, wherein said energy lag describes a transient energy consumption period preceding a change in outside temperature;
• a dispatch processor, coupled to said building lag optimizer circuit, configured to receive a plurality of energy lags, each corresponding to one of the buildings, and configured to generate a dispatch schedule for the demand response program event according to a prioritization of said plurality of energy lags;
• and
• a dispatch control circuit, coupled to said dispatch processor, configured to control a specified load shedding by performing load shedding actions in the order provided by said dispatch schedule, wherein said dispatch schedule directs for dispatch of ones of said buildings having greater energy lags prior to others of said buildings having lesser energy lags.

• performing a regression analysis on the each of the plurality of energy use data sets to yield corresponding regression parameters and a corresponding residual;
• determining a least valued residual from all residuals yielded by the regression analysis, the least valued residual indicating a corresponding energy lag for the each of the buildings, wherein the corresponding energy lag describes a transient energy consumption period preceding a change in outside temperature;
• using energy lags for all of the buildings to generate a dispatch schedule for the demand response program event according to a prioritization of the energy lags;
• and
• controlling a specified load shedding by performing load shedding actions in the order provided by the dispatch schedule, wherein the dispatch schedule directs for dispatch of ones of the buildings having greater energy lags prior to others of the buildings having lesser energy lags.
