Résumé

In the context of global warming, the European Union (EU) is setting increasingly ambitious targets to phase down CO2 emissions. The designated path towards carbon neutrality especially includes the electrification of residential building sector thanks to massive deployment of Heat Pump (HP) in replacement of fossil fuel-based heating systems. Buildings, being widely electrified, could become a major actor of the electrical grid stability through the development of flexibility services. To that extent, many studies focused on flexibility provided by HPs especially in simulation environment. To do so, a virtual test bench is generally created to represent the system {HP + Building}. However, those studies tend to consider simplified representation of HPs and their embedded control strategy that might lead to some discrepancies when applying flexibility schemes.
In this paper, a complete methodology for the creation and validation of a specific HP digital twin on the Dymola software is proposed. This methodology relies on multiple test sequences realized in climatic chambers with an Air to Water HP. Firstly, manufacturer data completed by a series of static conditions tests are used to calibrate the HP model. Secondly, scenario-based Hardware-In-the-Loop (HIL) experimental tests offer complete validation of both HP dynamic behaviour and its control strategy. Thirdly, other test series reproducing off-grid periods are carried out in order to compare how the developed HP model performs compared to literature models while being subject to flexibility orders. Finally, this paper gives insight on the impact of the modelling accuracy of the HP and its internal control rules when accounting for flexibility; and therefore, for the development of flexibility designed controllers.
