Demand side management in district heating systems [PDF]

open access: yesProceedings of the 6th international joint conference on Autonomous agents and multiagent systems, 2007
This paper describes a multiagent system that has made the voyage from research project to commercialised product. The purpose for the multiagent system is to dynamically control a system so that the load of the system is below certain threshold values without reduction of quality of service and by that, to avoid the usage of top load production ...
