Method and apparatus for controlling power grid member behavior
A system and method for controlling a behavior of at least one member of a local power grid. In one embodiment, the system comprises a monitoring system, comprising at least one processor, for obtaining a measure of grid stress and deriving at least one of financial incentives and financial disincentives, based on the measure of grid stress, to cause at least one member of the local grid to change behavior.
1. A system for behavior-based tertiary control of a local grid comprising a member, comprising:
a meter associated with the member and connected to at least one of a smart energy generator, smart energy storage, or smart energy load each comprising a controller configured to balance power generation and consumption of the local grid based on data comprising at least grid frequency or grid voltage that are continuously and autonomously sampled at a predetermined rate by the controller and compared to periodically updated setpoint values in real time and without any direct interaction from the member with the controller; and
a monitoring system operatively coupled to the controller of the meter and programmed to receive and process measured data to determine grid stress based on a production and consumption of both reactive power and real power of the member, establish an economic value for the production and consumption of the both reactive power and real power of the member based on a billing curve unique to the member, and determine a financial incentive for the member when the member produces more power than the member requires for consumption or storage and other members are capable of consuming the more power or a financial disincentive when the member produces the more power than the member requires for consumption or storage and the other members are not capable of consuming the more power to maintain balance of power generation within local grid,
wherein the monitoring system is operatively coupled to a power line of the local grid and is further programmed to:
measure an amount of real power flow and an amount of reactive power flow at the power line to determine both the reactive power and real power of the member to establish energy costs throughout the local grid; and
disconnect the member from the local grid when a cost of energy from the local grid is too high.
2. The system of claim 1 , wherein the monitoring system is further configured to establish the economic value by identifying a point on the billing curve that corresponds to the real power.
3. The system of claim 1 , wherein the billing curve denotes values for the real power vs. financial amounts per kilowatt hour.
4. The system of claim 1 , wherein a y-intercept of the billing curve is offset from zero by an amount that represents a tax on the member of the local grid.
5. The system of claim 1 , wherein the monitoring system is further configured to establish the economic value by identifying a point on the billing curve that corresponds to the reactive power.
6. The system of claim 1 , wherein the billing curve denotes values for the reactive power vs. financial amounts per kilovolt-ampere reactive hour.
7. A method for behavior-based tertiary control of a local grid comprising a member, comprising:
balancing, via a controller of a meter associated with the member and connected to at least one of a smart energy generator, smart energy storage, or smart energy load, power generation and consumption of the local grid based on data comprising at least grid frequency or grid voltage that are continuously and autonomously sampled at a predetermined rate by the controller and compared to periodically updated setpoint values in real time and without any direct interaction from the member with the controller;
receiving and processing, at a monitoring system operatively coupled to the controller of the meter and a power line of the local grid, measured data;
determining grid stress based on a production and consumption of both reactive power and real power of the member;
establishing an economic value for the production and consumption of both reactive power and real power of the member based on a billing curve unique to the member;
determining a financial incentive for the member when the member produces more power than the member requires for consumption or storage and other members are capable of consuming the more power or a financial disincentive when the member produces the more power than the member requires for consumption or storage and the other members are not capable of consuming the more power to maintain balance of power generation within local grid;
measuring an amount of real power flow and an amount of reactive power flow at the power line to determine both the reactive power and real power of the member to establish energy costs throughout the local grid; and
disconnecting the member from the local grid when a cost of energy from the local grid is too high.
8. The method of claim 7 , wherein the monitoring system is further configured to establish the economic value by identifying a point on the billing curve that corresponds to the real power.
9. The method of claim 7 , wherein the billing curve denotes values for the real power vs. financial amounts per kilowatt hour.
10. The method of claim 7 , wherein a y-intercept of the billing curve is offset from zero by an amount that represents a tax on the member of the local grid.
11. The method of claim 7 , wherein the monitoring system is further configured to establish the economic value by identifying a point on the billing curve that corresponds to the reactive power.
12. The method of claim 7 , wherein the billing curve denotes values for the reactive power vs. financial amounts per kilovolt-ampere reactive hour.
