1. A system configured to manage power consumption of a building and storage by controlling a refrigeration system within the building, the system comprising:
one or more processors, configured by machine-readable instructions, that are capable of controlling the refrigeration system, wherein the controlling of the refrigeration system includes activating one or more compressors, deactivating unloaders, increasing frequency of variable frequency drives for active ones of the one or more compressors, and controlling circuit control valves connected to one or more evaporators, the machine-readable instructions configuring the one or more processors to:
receive input defining a power target and a time interval, wherein the power target is for the time interval;
determine system information characterizing the refrigeration system, wherein the refrigeration system includes one or more cases, the one or more compressors, and the one or more evaporators, wherein the one or more cases cool, maintain coldness, freeze, or keep frozen food products and store the food products;
determine power usage of the building that includes the refrigeration system by calculating an amount of energy the building consumes per unit of time based on a regression model, a time of a day, the day of a week, an occupancy value, and an outside air temperature value;
determine precooling control actions based on the system information, the power target, and the time interval, wherein the precooling control actions include one or more of activating the one or more compressors, deactivating the unloaders, increasing frequency of the variable frequency drives for the compressors that are active, and controlling circuit control valves connected to the one or more evaporators;
determine load shedding control actions based on the system information, the power target, and the time interval;
generate a control schedule for the refrigeration system to effectuate the precooling control actions and/or load shedding control actions based on the power target, the time interval, and the power usage, wherein the precooling control actions and load shedding control actions facilitate acquisition of electrical power or distribution of the electrical power; and
effectuate the precooling control actions and/or load shedding control actions for the refrigeration system in accordance with the control schedule.
