NOTICE TYPE: W-A080219-01 Operations
SHORT DESCRIPTION: Implementation of system change to account for dynamic voltage stability limits for the Panhandle Generic Transmission Constraint
ERCOT Market Participants
August 2, 2019
ERCOT is implementing a change to its Real-Time systems for the Panhandle Generic Transmission Constraint (GTC). This change is being implemented to account for a dynamic voltage stability issue for a particular outage scenario where the limit cannot be determined
by the Voltage Stability Assessment Tool (VSAT) in Real-Time.
The purpose of this notice is to provide simultaneous notification to all ERCOT Market Participants of the system change being implemented, as it may impact limits associated with the Panhandle
GTC. ERCOT will discuss this issue in more detail at the Reliability and Operations Subcommittee (ROS) meeting on August 8, 2019, during the “ERCOT Reports” section of the agenda.
