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.<br/><br/>If LoadResponseCharacteristic.exponentModel is True, the voltage exponents are specified and used as to calculate:<br/><br/>Active power component = Pnominal * (Voltage/cim:BaseVoltage.nominalVoltage) ** cim:LoadResponseCharacteristic.pVoltageExponent<br/><br/>Reactive power component = Qnominal * (Voltage/cim:BaseVoltage.nominalVoltage)** cim:LoadResponseCharacteristic.qVoltageExponent<br/><br/>Where  * means "multiply" and ** is "raised to power of".<br/>
