Detailed Description

Models the characteristic response of the load demand due 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".
