System And Method For Interactive Demand Response For Controlling And Routing Power To One Or More Irrigation Systems
The present invention provides an interactive demand response system for controlling and routing power to one or more irrigation systems. According to a preferred embodiment of the present invention, a system is provided which includes a power station load control CPU and a terminal interface module to allow growers to sign up for and selectively override load control events via any web-connected computer, tablet, or smartphone. Further, the present invention preferably generates automated text and email alerts for upcoming load control events including the start and end times for each event. Further, the present invention may provide for displays of current system demand within groups of load control devices before, during, and after load control events. Further the system of the present invention preferably includes the creation and transmission of messages and reports which provide a recap for the power company and/or the growers and which detail the level of participation, power usage, timing of load control events, and the selection of overrides.

- 1. A method of providing an interactive demand response system for controlling and routing power to one or more irrigation systems, the method comprising:
storing irrigation system information for a given grower, wherein the stored information comprises load information for each piece of equipment under load control for the grower; calculating a load control schedule, wherein the load control schedule c arises a calculation of the desired run periods for a plurality of irrigation systems; initiating a load control event message, wherein the load control event message comprises notification of the dates and time of upcoming load control events; receiving the scheduled time and duration of the load control event at a grower control terminal; calculating and comparing the increased electricity cost of opting out of the scheduled load control event based at least in part on the growth stage of a given crop; opting out of the load control event and allowing a given irrigation system to operate during the scheduled load control event; transmitting changes in the price or the duration of the load control event to the grower; receiving a first set of data indicating the number of growers opting out of the load control event; updating the increased electricity cost of overriding the scheduled load control event based on the number of growers opting out of the load control event; and opting back into a load control event based on the updated increased electricity cost.
- 3. A system for controlling and routing power to one or more irrigation systems via a power transmission control system which feeds power to the irrigation systems via an electrical transmission network, wherein the system comprises:
a first irrigation system, wherein the first irrigation system comprises a first irrigation machine which operates using power supplied by the electrical transmission network; a second irrigation system, wherein the second irrigation system comprises a second irrigation machine which operates using power supplied by the electrical transmission network; a first power load control switch, wherein the first power load control switch operates in a first ON state which allows electricity to flow into the first irrigation system and a second OFF state which restricts electricity from flowing into the first irrigation system; a second power load control switch, wherein the second power load control switch operates in a first ON state which allows electricity to flow into the second irrigation system and a second OFF state which restricts electricity from flowing into the second irrigation system; an operator power control unit, wherein the operator power control unit controls the ON and OFF states of the first power load control switch and the second power load control switch; further wherein the operator power control unit monitors the transmission of electricity to the first irrigation system and to the second irrigation system; further wherein the operator power control unit is comprised of an internet appliance which is configured to interface with the power station load control processing unit; a load control database, wherein the load control database stores and updates predicted loads for upcoming time periods; further wherein the load control database receives updates from a plurality of remote data sources; a power station load control processing unit; wherein the power station load control processing unit receives forecast data from the load control database; wherein the power station load control processing unit is programmed to execute load control events; a terminal interface module, wherein the terminal interface module comprises a web-interface appliance which allows data and instructions from the power station load control processing unit to be accessed; and a grower control terminal, wherein the grower control terminal is comprised of an internet appliance which is configured to interface with the power station load control processing unit and the operator power control unit;
