                                        LoadResponseCharacteristic

Models the characteristic response of the load demand due to to changes in system conditions such as voltage and frequency. This is not related to demand response. If LoadResponseCharacteristic.exponentModel is True, the voltage exponents are specified and used as to calculate: Active power component = Pnominal * (Voltage/cim:BaseVoltage.nominalVoltage) ** cim:LoadResponseCharacteristic.pVoltageExponent Reactive power component = Qnominal * (Voltage/cim:BaseVoltage.nominalVoltage)** cim:LoadResponseCharacteristic.qVoltageExponent Where * means 'multiply' and ** is 'raised to power of'.

(Constructor)

 

Initialises a new 'LoadResponseCharacteristic' instance.

Parameters:
  • pVoltageExponent - Exponent of per unit voltage effecting real power. This model used only when 'useExponentModel' is true.
  • qConstantCurrent - Portion of reactive power load modeled as constant current. Used only if the useExponentModel is false. This value is noralized against the sum of qZ, qI, and qP.
  • pFrequencyExponent - Exponent of per unit frequency effecting active power
  • exponentModel - Indicates the exponential voltage dependency model (pVoltateExponent and qVoltageExponent) is to be used. If false, the coeficient model (consisting of pConstantImpedance, pConstantCurrent, pConstantPower, qConstantImpedance, qConstantCurrent, and qConstantPower) is to be used.
  • qConstantImpedance - Portion of reactive power load modeled as constant impedance. Used only if the useExponentModel is false. This value is noralized against the sum of qZ, qI, and qP.
  • pConstantCurrent - Portion of active power load modeled as constant current. Used only if the useExponentModel is false. This value is noralized against the sum of pZ, pI, and pP.
  • qFrequencyExponent - Exponent of per unit frequency effecting reactive power
  • pConstantPower - Portion of active power load modeled as constant power. Used only if the useExponentModel is false. This value is noralized against the sum of pZ, pI, and pP.
  • qVoltageExponent - Exponent of per unit voltage effecting reactive power. This model used only when 'useExponentModel' is true.
  • qConstantPower - Portion of reactive power load modeled as constant power. Used only if the useExponentModel is false. This value is noralized against the sum of qZ, qI, and qP.
  • pConstantImpedance - Portion of active power load modeled as constant impedance. Used only if the useExponentModel is false. This value is noralized against the sum of pZ, pI, and pP.
  • EnergyConsumer - The set of loads that have the response characteristics.
