Types ofDemand Response Control
Autonomous – Happens all by itself. Self-sensing of very local conditions. Sensors react with no communications.
Resource Initiated – DR polls a site/bulletin board for what information is desired.
Bulk Dispatched – System operator sends broad message to DR and DR responds.
Precision Dispatch – Full bi-directional communications. Integrate what is going on at DR and then decisions are made on what performance of DR is desired.
