Abstract

Embodiments provide systems, methods and apparatus for controlling an energy delivery system including providing an energy management system (EMS) having an automatic generation control (AGC) system including a load frequency control (LFC) module; executing two or more performance standard functions implemented within the LFC module using input data regarding the energy delivery system, wherein at least one of the performance standard functions is defined to be dependent upon another of the performance standard functions; and implementing corrections to the operation of the energy delivery system based upon solution results of executing the performance standard functions. Numerous other aspects are provided.

First claim

What is claimed is:

1. A method of controlling an energy delivery system, the method comprising:
providing an energy management system (EMS) at an Independent System Operator (ISO) control center, the EMS having an automatic generation control (AGC) system including a load frequency control (LFC) module;
providing one or more communication paths between the AGC of the EMS and each one of one or more electrical power generating resources remote from the EMS;
executing two or more performance standard functions implemented within the LFC module using input data regarding the energy delivery system, wherein at least one of the performance standard functions is defined to be dependent upon another of the performance standard functions;
generating solution results based on executing the performance standard functions; and
transmitting instructions to implement corrections, based at least in part on the solution results, via the one or more communication paths to at least one of the one or more electrical power generating resources remote from the EMS.

2. The method of controlling an energy delivery system of claim 1 , wherein the performance standard functions implemented within the LFC module include a Long Term North American Electric Reliability Corporation (NERC) Control Performance Standard 001 (CPS1) Control function, a Short Term CPS1 Control function, a Long Term NERC Control Performance Standard 002 (CPS2) Control function, and a Short Term CPS2 Control function, wherein Long Term refers to a time period of greater than a month and Short Term refers to a time period less than ten minutes.

3. The method of controlling an energy delivery system of claim 2 , wherein the Long Term CPS1 Control function and the Long Term CPS2 Control function are integrated, and wherein the Short Term CPS1 Control function and the Short Term CPS2 Control are integrated.

4. The method of controlling an energy delivery system of claim 1 , wherein the performance standard functions implemented within the LFC module include a Long Term CPS1 Control function, a Short Term CPS1 Control function, and a NERC Balancing Authority Area Control Error (ACE) Limit (BAAL) Control function, wherein Long Term refers to a time period of greater than a month and Short Term refers to a time period less than ten minutes.

5. The method of claim 4 , wherein the BAAL Control function is operative to calculate a clock-minute ACE and a clock-minute BAAL, monitor a clock-minute ACE average, and initiate a control action to correct the ACE back to the clock-minute BAAL responsive to the ACE exceeding the clock-minute BAAL.

6. The method of controlling an energy delivery system of claim 1 , wherein the input data includes historical data, static data, and dynamic data.

7. The method of controlling an energy delivery system of claim 1 , wherein providing the LFC module includes providing an LFC application and a coordinated CPS control engine, and wherein the LFC application is operative to call the performance standard functions in the coordinated CPS control engine.

8. A system comprising:
a process controller;
one or more communication paths coupled between the process controller and one or more electrical power generating resources of an energy delivery system;
a memory coupled to the process controller and having instructions stored therein that, when executed by the process controller, cause the process controller to:
execute two or more performance standard functions using input data regarding an energy delivery system, wherein at least one of the performance standard functions is defined to be dependent upon another of the performance standard functions, to generate solution results; and
transmit one or more instructions to implement corrections via at least one of the one or more communication paths to at least one of the one or more electrical power generating resources of the energy delivery system;
wherein the one or more instructions are based, at least in part, on the solution results.

9. The system of claim 8 , wherein the performance standard functions implemented within the LFC module include a Long Term CPS1 Control function, a Short Term CPS1 Control function, a Long Term CPS2 Control function, and a Short Term CPS2 Control function, wherein Long Term refers to a time period of greater than a month and Short Term refers to a time period less than ten minutes.

10. The system of claim 9 , wherein the Long Term CPS1 Control function and the Long Term CPS2 Control function are integrated, and wherein the Short Term CPS1 Control function and the Short Term CPS2 Control function are integrated.

11. The system of claim 8 , wherein the performance standard functions include a Long Term CPS1 Control function, a Short Term CPS1 Control function, and a BAAL Control function, wherein Long Term refers to a time period of greater than a month and Short Term refers to a time period less than ten minutes.

12. The system of claim 11 , wherein the BAAL Control function is operative to calculate a clock-minute ACE and a clock-minute BAAL, monitor a clock-minute ACE average, and initiate a control action to correct an ACE back to the clock-minute BAAL responsive to the ACE exceeding the clock-minute BAAL.

13. The system of claim 8 , wherein the input data includes historical data, static data, and dynamic data.

14. The system of claim 8 , further comprising:
an LFC application and a coordinated CPS control engine,
wherein the LFC application is operative to call the performance standard functions in the coordinated CPS control engine.

15. A system, comprising:
a load frequency control (LFC) application stored within the system that, when executed by a process controller, causes the process controller to generate an output data structure and to store solution results in an operational database of an energy management system (EMS);
a coordinated CPS control engine stored within the system that, when executed by the process controller, causes the process controller to receive input data, execute two or more performance standard functions called by the LFC application, and to populate the output data structure with solution results; and
one or more communication paths coupled between the process controller and one or more electrical power generating resources, the one or more communication paths configured to carry instructions from the process controller to at least one of the one or more electrical power generating resources to implement corrections;
wherein at least one of the performance standard functions executable by the coordinated CPS control engine is defined to be dependent upon another of the performance standard functions.
