Annex 57 Flexibility by Implementation of Heat Pump in Multi-Vector Energy Systems Final Report
The present report documents the results of HPT Annex 57 “Flexibility by implementation of heat pumps in multi-vector energy systems and thermal networks”. The Annex was initiated in the spring of 2019 and started officially in January 2020. The planned work was three years, and the project is finalized within the planned period, despite the Covid-19 pandemic which caused an abnormal startup without physical meetings. The active Annex group consisted of five countries (Austria, Denmark, Germany, the Netherlands, and Sweden).
Annex 57 has focused on solutions where heat pumps can create flexibility to the electrical grid. When the project was initiated, the aim was to focus on flexibility from heat pumps connected to district heating as the project was based on the results from HPT Annex 47 Heat Pumps in District Heating and Cooling Systems. Flexibility from individual heat pumps have also been included in the scope of this annex during the project as some participants and the IEA HPT Executive Committee had a wish to extend the scope to include individual heat pumps as well. The focus has been to describe what is flexibility and what the is potential of flexibility.
