Load<br />

The Set To action will set the selected bus’ generation or specified generator's parameters to<br />

a specified Amount. Generator Set To actions can be done on a bus basis (impacting the<br />

total generation of all generators at the selected bus) or can be targeted at a specified<br />

generator. Generators that are adjusted by a Set To action will have their AGC Status set to<br />

No. If there are no on-line generators at the selected generator bus, no generation change<br />

will occur. Generator parameters can be set in Percent, MW, or Setpoint Voltage. When<br />

the generation is set in Percent, total generator MW output will be set to a value based on<br />

the specified percent of the current total generator MW output. When the generation is set in<br />

MW, total generator MW output will be set to the specified MW amount. When the<br />

generation is set in Setpoint Voltage, the voltage set-point of all generators at the selected<br />

bus will be set to the specified amount in per unit.<br />

When using the Set To action, the Make-up Power Sources button is enabled and power<br />

sources can be specified to account for the changes in generation due to the contingency<br />

action.<br />

Change By<br />

The Change By action will change the selected bus’ generation or specified generator's<br />

parameters by a specified Amount. Generator Change By actions can be done on a bus basis<br />

(impacting the total generation of all generators at the selected bus) or can be targeted at a<br />

specified generator. Generators that are adjusted by a Change By action will have their AGC<br />

Status set to No. If there are no on-line generators at the selected generator bus, no<br />

generation change will occur. Generator parameters can be changed in Percent, MW, or<br />

Setpoint Voltage. When the change is in Percent, total generator MW output will be<br />

changed based on the specified percent of the total current generator MW output. When the<br />

change is in MW, total generator MW output will be changed by the specified MW amount.<br />

When the change is in Setpoint Voltage, the voltage set-point of all generators at the<br />

selected bus will be changed by the specified amount in per unit.<br />

When using the Change By action, the Make-up Power Sources button is enabled and<br />

power sources can be specified to account for the changes in generation due to the<br />

contingency action.<br />

Open<br />

The Open action will set the Status of the selected load to Open if the load Status is Closed. If<br />

the load Status is already Open, this action does nothing.<br />

When using the Open action, the Make-up Power Sources button is enabled and power<br />

sources can be specified to account for the changes in load due to the contingency action.<br />

Open Breakers<br />

Close<br />

See the special topic on Open Breakers for more detail.<br />

The Close action will set the Status of the selected load to Closed if the load Status is Open. If<br />

the load Status is already Closed, this action does nothing.<br />

When using the Close action, the Make-up Power Sources button is enabled and power<br />

sources can be specified to account for the changes in load due to the contingency action.<br />

Close Breakers<br />

Move<br />

See the Close Breakers for Contingencies topic below.<br />

The Move action allows the transferring of load from an existing load bus to another bus. A<br />

load move can be done on a bus basis (impacting the total load of all loads at the selected<br />

bus) or can be targeted at a specific load. Load may be moved in MW (const pf),<br />
