Generating unit long term economic participation factor.

Generating unit short term economic participation factor.

Generating unit economic participation factor. The sum of the participation factors across generating units does not have to sum to one. It is used for representing distributed slack participation factor. The attribute shall be a positive value or zero.

The data value of the X-axis variable, depending on the X-axis units.

The data value of the first Y-axis variable, depending on the Y-axis units.

The data value of the second Y-axis variable (if present), depending on the Y-axis units.

This is a deadband used with discrete control to avoid excessive update of controls like tap changers and shunt compensator banks while regulating. The units of those appropriate for the mode. The attribute shall be a positive value or zero. If RegulatingControl.discrete is set to "false", the RegulatingControl.targetDeadband is to be ignored. Note that for instance, if the targetValue is 100 kV and the targetDeadband is 2 kV the range is from 99 to 101 kV.

The target value specified for case input. This value can be used for the target value without the use of schedules. The value has the units appropriate to the mode attribute.

The voltage at the tap step divided by rated voltage of the transformer end having the tap changer. Hence this is a value close to one. For example, if the ratio at step 1 is 1.01, and the rated voltage of the transformer end is 110kV, then the voltage obtained by setting the tap changer to step 1 to is 111.1kV.

The first value at the time. The meaning of the value is defined by the derived type of the associated schedule.

The second value at the time. The meaning of the value is defined by the derived type of the associated schedule.
