A new district heating network in Sweden is based on a digital control system that allows for what its developers call virtual energy storage in buildings.
A control system manages the heat network, co-ordinating production and distribution with consumption through real-time analysis. Stored heat can be redistributed across the network, reducing peak load.
‘Through intelligent property controls the energy reserve can be put to better use in other parts of the network, thus reducing so-called peak load without affecting the indoor climate,’ the developers said. ‘This evens out the load on the grid over a 24-hour period, so the boilers do not need to work as hard and the flow through the district-heating pipes is more uniform.’
