  opModFixedFlow

Details:
Notes: The opModFixedFlow function specifies a requested charge or discharge mode setpoint, in %setMaxChargeRate if negative value or %setMaxW or %setMaxDischargeRate if positive value (in hundredths).  SHALL be ignored if device is not a storage DER or setStorConnect is false.
Public FixedPowerFactor
  opModFixedPF

Details:
Notes: The opModFixedPF function specifies a requested fixed Power Factor (PF) setting, consisting of a signed displacement value. The PF sign (which SHALL be interpreted according to the EEI convention, where unity PF is considered unsigned) indicates the direction of reactive power flow. The actual displacement SHALL be within the limits established by setMinPF and setMinPFNeg. If issued simultaneously with other reactive power controls (e.g. opModFixedVAr) the control resulting in least var magnitude takes precedence.
Public FixedVAr
  opModFixedVAr

Details:
Notes: The opModFixedVAr function specifies the delivered or received reactive power limit setpoint.  The context for the limit value is determined by refType and SHALL be one of %setMaxW, %setMaxVAr, or %statVArAvail.  If issued simultaneously with other reactive power controls (e.g. opModFixedPF) the control resulting in least var magnitude takes precedence.
Public PerCent
  opModFixedW

Details:
Notes: The opModFixedW function sets the maximum active power generation level at the electrical coupling point as a percentage of set capacity (%setMaxW, in hundredths). This limitation may be met e.g. by reducing PV output or by using excess PV output to charge associated storage.
Public DERCurveLink
  opModFreqWatt

Details:
Notes: Specify DERCurveLink for curve type == 1.  The Frequency-Watt function limits active power generation or consumption when the line frequency deviates from nominal by a specified amount. The Frequency-Watt curve is specified as an array of Frequency-Watt pairs that are interpolated into a piecewise linear function with hysteresis.  The x value of each pair specifies a frequency in Hz. The y value specifies a corresponding active power output in %setMaxW * 100 (0 - 10000) (hundredths of a percent).
Public CurvePairType
  opModHVRT

Details:
Notes: Specify curve pair for curve type == 5.  The High Voltage Ride-Through (HVRT) function is specified by one or two duration-volt curves that define the operating region under high voltage conditions.  Each HVRT curve is specified by an array of duration-volt pairs that will be interpolated into a piecewise linear function that defines an operating region.  The x value of each pair specifies a duration (time at a given voltage in seconds). The y value of each pair specifies an effective percent voltage, defined as (100% * (locally measured voltage - setVRefOfs) / setVRef), in hundredths of a percent.  The upperLimit curve delineates the "must disconnect" region and SHALL be defined for this control to be active.  The (optional) lowerLimit curve delineates the "must remain connected" region. If the "must remain connected" curve is not specified, it is assumed to be the same as the "must disconnect" curve.
Public CurvePairType
  opModLVRT

Details:
Notes: Specify curve pair for curve type == 4.  The Low Voltage Ride-Through (LVRT) function is specified by one or two duration-volt curves that define the operating region under low voltage conditions.  Each LVRT curve is specified by an array of duration-volt pairs that will be interpolated into a piecewise linear function that defines an operating region.  The x value of each pair specifies a duration (time at a given voltage in seconds). The y value of each pair specifies an effective percent voltage, defined as (100% * (locally measured voltage - setVRefOfs) / setVRef), in hundredths of a percent.  The lowerLimit curve delineates the "must disconnect" region and SHALL be defined for this control to be active.  The (optional) upperLimit curve delineates the "must remain connected" region. If the "must remain connected" curve is not specified, it is assumed to be the same as the "must disconnect" curve.
Public DERCurveLink
  opModVoltVAr

Details:
Notes: Specify DERCurveLink for curve type == 0.  The static Volt-VAr function provides over- or under-excited VAr compensation as a function of measured voltage. The Volt-VAr curve is specified as an array of Volt-VAr pairs that are interpolated into a piecewise linear function with hysteresis. The x value of each pair specifies an effective percent voltage, defined as (100% * (locally measured voltage - setVRefOfs) / setVRef) and SHOULD support a domain of at least 0 - 13500 (in hundredths of a percent).  The y value specifies a target VAr output interpreted as SignedPerCent (10000 to -10000). The meaning of the y value is determined by yRefType and must be one of %setMaxW, %setMaxVAr, or %statVArAvail, all in hundredths of a percent.
Public DERCurveLink
  opModVoltWatt

Details:
Notes: Specify DERCurveLink for curve type == 3.  The Volt-Watt reduces active power output as a function of measured voltage. The Volt-Watt curve is specified as an array of Volt-Watt pairs that are interpolated into a piecewise linear function with hysteresis. The x value of each pair specifies an effective percent voltage, defined as (100% * (locally measured voltage - setVRefOfs) / setVRef) and SHOULD support a domain of at least 0 - 13500 (in hundredths of a percent).  The y value specifies an active power output in %setMaxW, (0 - 10000) in hundredths of a percent.
Public DERCurveLink
  opModWattPF

Details:
Notes: Specify DERCurveLink for curve type == 2.  The Watt-PF function varies Power Factor (PF) as a function of delivered active power. The Watt-PF curve is specified as an array of Watt-PF coordinates that are interpolated into a piecewise linear function with hysteresis.  The x value of each pair specifies a watt setting in %setMaxW, (0 - 10000) in hundredths of a percent. The PF output setting is a signed displacement in y value (PF sign SHALL be interpreted according to the EEI convention, where unity PF is considered unsigned). These settings are not expected to be updated very often during the life of the installation, therefore only a single curve is required.  If issued simultaneously with other reactive power controls (e.g. opModFixedPF) the control resulting in least var magnitude takes precedence.
Public UInt16
  rampTms

Details:
Notes: Requested ramp time, in hundredths of a second, for the device to transition from the current DERControl  mode setting(s) to the new mode setting(s). If absent, use default ramp rate (setWGrad).  Resolution is 1/100 sec.
