Certain exemplary embodiments provide a method comprising: detecting a NERC disturbance in an electrical power system; determining a first corrective action to return the electrical power system to a pre-disturbance level within a predetermined disturbance recovery time; determining a second corrective action to cause the electrical power system to meet one or more predefined NERC CPS compliance target values; and providing a corrective control signal to the electrical power system.

DETAILED DESCRIPTION Certain exemplary embodiments can provide a system comprising a set of modules useful for interfacing with an electrical power system.
One or more of the modules can minimize control actions and/or improve economics while remaining compliant with NERC performance criteria.
FIG.
1 is a block diagram of an exemplary embodiment of a system 1000, which can enable meeting AGC performance requirements while minimizing the associated generating costs due to load following and/or regulation.
These performance requirements can compare how well the control area's area control error (ACE) performed in conjunction with the frequency of the interconnection.
Certain exemplary embodiments can provide CPS real-time AGC control, CPS monitoring, and/or CPS reporting.
Certain exemplary embodiments can utilize look-ahead and/or anticipatory dispatch, such as Very Short Term Load Prediction.
System 1000 can comprise a CPS Real-time Control module (CPS Real-time Controller) 1100 for generation control and/or distribution of regulation.
CPS Real-time Control module 1100 can receive electrical power system information from a CPS Performance Monitoring module (CPS Performance Monitor) 1200, which can provide direct feedback on current and/or past AGC control performance.
Coupled to CPS Performance Monitoring module 1200 can be a CPS Reporting module (CPS Reporter) 1300, which can produce reports for NERC.
A Future Event Processing module (Future Event Processor) 1400, can coordinate scheduled events as an input into the calculation of overall required generation.
Coupled to Future Event Processing module 1400 can be a Dynamic Economic Dispatch module (Dynamic Economic Dispatcher) 1500, which can provide economic generator base-point trajectories to CPS Real-time Control module 1100.
Coupled to Dynamic Economic Dispatch module 1500 can be a Very Short Term Load Prediction module (Very Short Term Load Predictor) 1600, which can provide a very short term trajectory of up-coming demand for dispatch and/or CPS-based control
