Existing infrastructure in buildings, such as heat pumps or domestic hot water heaters, is usually operated to satisfy the thermal needs of residents purely. However, thanks to thermal storage capacities available in buildings’ thermal mass or water tanks, there exists energy flexibility in when to charge these storages. These flexibilities can be coordinated to satisfy other interests, e.g., from other players in the electric or thermal distribution grid. Controllers that optimally utilize these flexibilities are developed and implemented in the NEST demonstrator.
As system complexity increases, structured test specifications and experiment plans are necessary to facilitate experiment execution and replication. An example is provided here.
