Grid Connected Functionality

Dataset demonstrating the potential benefits that residential buildings can provide for frequency regulation services in the electric power grid. In a hardware-in-the-loop (HIL) implementation, simulated homes along with a physical laboratory home are coordinated via a grid aggregator, and it is shown that their aggregate response has the potential to follow the regulation signal on a timescale of seconds. Connected (communication-enabled), devices in the National Renewable Energy Laboratory's (NREL's) Energy Systems Integration Facility (ESIF) received demand response (DR) requests from a grid aggregator, and the devices responded accordingly to meet the signal while satisfying user comfort bounds and physical hardware limitations.

The Topics table contains a list of availabe topics on the volttron message bus. (topic_id INTEGER PRIMARY KEY, topic_name TEXT NOT NULL, UNIQUE(topic_name)) The data table is a timeseries database of the topics from the topics table mapped by topic_id. (ts timestamp NOT NULL, topic_id INTEGER NOT NULL, value_string TEXT NOT NULL, UNIQUE(ts, topic_id))
