“…A surplus of electricity production can lead to curtailment of renewable plants, while a potential deficit requires the constant availability of peaking power plants to compensate for the lack of renewable energy. Furthermore, distribution infrastructure needs to be maintained or upgraded to enable always higher short-term peaks and variations in the grid caused by the increasing number of prosumers [3]. Overall, the traditional vision where the "production follows the demand" needs a paradigm shift towards a concept where the "demand follows the production".…”

The present work constitutes a review of the existing literature on supervisory control for improving the energy flexibility provided by heat pumps in buildings. A distinction was drawn between rule-based controls (RBC) and model predictive controls (MPC), given the clear differences in their concept and complexity. For both kinds, the different objectives claimed by these strategies have been reviewed, as well as the control inputs, disturbances and constraints. Notably in MPC, the monetary objective (reduction of the energy costs) has been the most utilized in the literature, therefore the authors advocate for the further study of other objectives related to energy flexibility. Further than the control strategies themselves, the different thermal storage options (necessary to activate the flexibility) have also been reviewed, the built-in thermal mass seeming more costeffective than water buffer tanks in this regard. Based on these conclusions, recommendations for further research topics are drawn.
