Description

The LoadResponseCharacteristic is different for steady state and for short time frame dynamics simulations. The form of the model is the same, but the parameters are different, typically PQ for steady state and more complex voltage dependency for short term voltage drops in transient stablity.

Proposed Solution

Modify multipliicty of the EnergyConsumer-LoadResponseCharacteristic to allow multiple load characteristics per load instance. Also add an attribute to LoadResponseCharacteristic to specify for what purpose the response characteristic is used.

Decision

Discussed in the 05-Apr-2023 UTF13 weekly call.

Decision: This issue to be closed. The rationale for closing that the dynamics model replaced the need for addressing this issue originally raised for CIMv13. If someone has a better use case for changing cardinality between EnergyConsumer-LoadResponseCharacteristic this can be revisited.
