DER refers to distributed energy resources; DR refers to demand response; EV refers to electric vehicles. DERP, EVA, HEAT, SAM, eFleet, and LDM identify models or modules with their own scope and documentation.

Definitions and units inside an individual model’s methodology take precedence over broad glossary descriptions. See the [model catalogue](https://docs.models.dunsky.com/en/models/catalogue.md) and [repository directory](https://docs.models.dunsky.com/en/development/repositories.md).
