Abstract

Systems and methods to manage power consumption of a building and storage by controlling a refrigeration system within the building are disclosed. Exemplary implementations may: receive input defining an average power target and a time interval; determine system information characterizing a refrigeration system; determine build information characterizing power usage of a building that includes the refrigeration system; determine precooling control actions based on the system information, the average power target, and the time interval; determine load shedding control actions based on the system information, the average 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 average power target, the time interval, and the building information; and effectuate the precooling control actions and/or load shedding control actions for the refrigeration system in accordance with the control schedule.

Claims (25)

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.

2. The system of claim 1 , wherein generating the control schedule is based on a required power target and/or a building temperature, wherein the required power target is power required by the building to operate.

3. The system of claim 2 , wherein the regression model is based on historical facility operations, wherein the system information includes the historical facility operations.

4. The system of claim 1 , wherein the system information includes suction pressures, compressor information, case information, circuit control information, defrost schedules, door information, and/or pressure information.

5. The system of claim 1 , wherein the load shedding control actions include deactivating some of the compressors, activating unloaders, and/or decreasing frequency of variable frequency drives for the compressors that are active.

6. A method to manage power consumption of a building and storage by controlling a refrigeration system within the building via 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 method comprising:

receiving, by the one or more processors, input defining a power target and a time interval, wherein the power target is for the time interval;

determining, by the one or more processors, 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;

determining, by the one or more processors, 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;

determining, by the one or more processors, 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;

determining, by the one or more processors, load shedding control actions based on the system information, the power target, and the time interval;

generating, by the one or more processors, 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

effectuating, by the one or more processors, the precooling control actions and/or load shedding control actions for the refrigeration system in accordance with the control schedule.

7. The method of claim 6 , wherein generating the control schedule is based on a required power target and/or a building temperature, wherein the required power target is power required by the building to operate.

8. The method of claim 7 , wherein the regression model is based on historical facility operations, wherein the system information includes the historical facility operations.

9. The method of claim 6 , wherein the system information includes suction pressures, compressor information, case information, circuit control information, defrost schedules, door information, and/or pressure information.

10. The method of claim 6 , wherein the load shedding control actions include deactivating some of the compressors, activating unloaders, and/or decreasing frequency of variable frequency drives for the compressors that are active.
