Posturing Tools

Posturing Load Shedding Control *More*

Postured Load Shedding Control is performed in a composite control region at a sufficient control level to prevent voltage instability for all of the contingencies that affect one or more loadpockets. This tool can be used to design Under Voltage Load Shedding to take action when the voltages produced at the point of non solution are above a certain threshold for contingencies associated with voltage instability in these loadpockets. *More*

Posturing Unit Commitment *More*

Unit Commitment Changes can greatly reduce the number of contingencies that cause voltage instability by providing reactive reserves to subnetworks that are in the control region for one or more loadpockets. By adding these reactive reserves, the Unit Commitment changes can dramatically reduce the structural and contingency vulnerability of these loadpockets in the study region. *More*

Posturing Voltage Rescheduling *More*

Postured Voltage Rescheduling Control is performed on the generators in a composite control region at a sufficient control level to prevent voltage instability for all of the contingencies that affect one or more loadpockets. This tool can be used to design Under Voltage Capacitor Protection to take action when the voltages produced at the point of non solution are above a certain threshold for contingencies associated with voltage instability in these loadpockets. *More*
