DER related curves such as Volt-Var mode curves. Relationship between an independent variable (X-axis) and a dependent variable (Y-axis).<br/>
Attribute
Public boolean
  autonomousVRefEnable
Details:
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 Volt-Var 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/>
Public UInt32
  autonomousVRefTimeConstant
Details:
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/>
Public TimeType
  creationTime
Details:
Notes: The time at which the object was created.<br/>
Public DERCurveType
  curveType
Details:
Notes: Specifies the associated curve-based control mode.<br/>
Public UInt16
  openLoopTms
Details:
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/>
Public UInt16
  rampDecTms
Details:
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/>
Public UInt16
  rampIncTms
Details:
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/>
Public UInt16
  rampPT1Tms
Details:
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/>
Public PerCent
  vRef
Details:
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/>
Public PowerOfTenMultiplierType
  xMultiplier
Details:
Notes: Exponent for X-axis value.<br/>
Public PowerOfTenMultiplierType
  yMultiplier
Details:
Notes: Exponent for Y-axis value.<br/>
Public DERUnitRefType
  yRefType
Details:
Notes: The Y-axis units context.<br/>
