Summary
In a power system with an increased share of electricity from intermittent renewable sources heat pumps can act as a large, aggregated flexibility resource. This can help to balance variations in electricity production and to reduce problems with bottlenecks in the power system. In this study a concept based on using the heat pump manufacturers cloud solutions to communicate demand response between an aggregator and individual heat pumps is investigated. The manufacturers cloud solutions were first released about ten years ago, meaning numerous heat pumps installed are ready to be used for flexibility with the missing piece being communication. Possibilities and constrains related to the concept have been investigated in an interview study with nine technical experts from the major heat pump manufacturers in Sweden. A workshop with those experts and additional stakeholder complemented it. Several barriers to solve were identified. Heat pumps are difficult to securely control rapidly and thus communicating flexibility control on beforehand has clear benefits. The transmission system operator normally has high accuracy demands, something villa heat pumps today cannot meet as most of them lack electricity meters. Here compromising on accuracy is likely necessary. Alternatives to standardize the communication between the aggregator via the cloud services to the individual heat pumps has been investigated. From a heat pump perspective EEBUS and OpenADR are promising.
