Demand Response (DR)
Demand Response (DR) is the controlled adjustment of electricity consumption in response to:
- Price signals, or
- Dispatch instructions from a system operator or aggregator
Its purpose is to support system balancing, reduce costs, and improve reliability.
If baseline demand is :
where is the change in demand induced by DR.
Role
Electricity systems must satisfy:
DR shifts part of the balancing responsibility from generation to demand.
Key Idea
DR makes electricity demand ==flexible and controllable==, allowing it to be treated as a system resource.
