Ace Equation
(NIA-NIS)-10xBx (FS-FA)-IME
CPS 1- control performance standard
must be 100% or greater- distribution of all BAs Ace in an Interconnection and based on expected freqency performance within the indiviual interconnection. Statistical measure of ace variability. Measures ace in combonation with frequency error
CPS 2- control performance standard
90% or greater- limits the magnitude of the impact at a BA places on the transmission resources in its interconnection. Designed to limit the BA’s unscheduled Power Flows. To protect the tie lines.
CPS 1 - control performance standard
can be viewed as a measure of whether a BA is maintaining enough Regulating Reserves
CPS 2 control performance standard
can be viewed as whether a BA is maintaining enough operating reserves
DCS control performance
measure a BA or RSG is maintaning enough Contingency Reserves
CPS 1 & CPS 2
report compliance to Nerc on monthly basis & must be in compliance with the CPS during both normal and disturbance conditions
DCS
You can report compliance to the DCS as a BA or RSG.
DCS
Entities must be able to recover from their single most severe contigency.
DCS
A BA is responsible for recovering from a reportable disturbance within 15 minutes and contingency reserves must be back in 90 minutes. unless combined magnitude is greater than single most severe contingency.
DCS
REPORTED TO NERC QUARTLEY - 4X A YEAR
FREQUENCY
60HZ
BIAS
SHALL BE SET CLOSE TO BA’S FREQUENCY RESPONSE CHARACTERISTIC
WECC
OPERATES IN BIAS TIE LINE MODE
BIAS
REVIEWED ONCE A YEAR - SET AT 1% OF ESTIMATED PEAK LOAD OR 1% OF ESTIMATED GENERATION LOAD
