LONG DESCRIPTION: The Real-Time CSC Limit Calculator was placed into service on full-time basis in the ERCOT control room beginning May 28, 2008.
Background
The CSC Limits are computed and posted by
Operations during the day-ahead planning process. These limits are based
on the day ahead Resource Plans and forecasted system conditions. ERCOT
has experienced periods in real-time where the flow across the CSCs
are below the day ahead limits but there are post contingency
overloads appearing in the ERCOT Real-Time Contingency Analysis
(RTCA). There has also been times when the flow across the CSCs are
exceeding the day ahead limits but there are no post contingency overloads in
RTCA. ERCOT has frequently updated the limits under this scenario but has
not been able to keep up with the changes to the system because of the manual
process required to update the limits. The CSC Limit Calculator will
automate this process and allow ERCOT to update the limits as often as once an
hour.
Benefits
The Real-Time CSC Limit
Calculator will allow ERCOT to update the limits on the CSC in a more timely
manner and allow ERCOT to maximize the flow across
zones.
