Attribute Scope Type
autonomousVRefEnable Public boolean
Notes: If the curveType is opModVoltVar, then this field MAY be present. If the curveType is not opModVoltVar, then this field SHALL NOT be present. Enable/disable autonomous vRef adjustment. When enabled, the Volt-Var curve characteristic SHALL be adjusted autonomously as vRef changes and autonomousVRefTimeConstant SHALL be present. If a DER is able to support the Volt-Var DERControl Mode but is unable to support autonomous vRef adjustment, then the DER SHALL execute the curve without autonomous vRef adjustment. If not specified, then the value is false.<br/>
autonomousVRefTimeConstant Public UInt32
Notes: If the curveType is opModVoltVar, then this field MAY be present. If the curveType is not opModVoltVar, then this field SHALL NOT be present. Adjustment range for vRef time constant, in hundredths of a second.<br/>
creationTime Public TimeType
Notes: The time at which the object was created.<br/>
curveType Public DERCurveType
Notes: Specifies the associated curve-based DERControl Mode.<br/>
openLoopTms Public UInt16
Notes: Open loop response time, the time to ramp up to 90% of the new target in response to the change in voltage, in hundredths of a second. Resolution is 1/100 sec. A value of 0 is used to mean no limit. When not present, the device SHOULD follow its default behavior.<br/>
rampDecTms Public UInt16
Notes: Decreasing ramp rate, interpreted as a percentage change in output capability limit per second (e.g. %setMaxW / sec).  Resolution is in hundredths of a percent/second. A value of 0 means there is no limit. If absent, ramp rate defaults to setGradW.<br/>
rampIncTms Public UInt16
Notes: Increasing ramp rate, interpreted as a percentage change in output capability limit per second (e.g. %setMaxW / sec).  Resolution is in hundredths of a percent/second. A value of 0 means there is no limit. If absent, ramp rate defaults to rampDecTms.<br/>
rampPT1Tms Public UInt16
Notes: The configuration parameter for a low-pass filter, PT1 is a time, in hundredths of a second, in which the filter will settle to 95% of a step change in the input value. Resolution is 1/100 sec.<br/>
vRef Public PerCent
Notes: If the curveType is opModVoltVar, then this field MAY be present. If the curveType is not opModVoltVar, then this field SHALL NOT be present. The nominal AC voltage (RMS) adjustment to the voltage curve points for Volt-Var curves.<br/>
xMultiplier Public PowerOfTenMultiplierType
Notes: Exponent for X-axis value.<br/>
yMultiplier Public PowerOfTenMultiplierType
Notes: Exponent for Y-axis value.<br/>
yRefType Public DERUnitRefType
Notes: The Y-axis units context.<br/>
