A predictive model for smart control of a domestic heat pump and thermal storage

The purpose of this paper is to develop and validate a predictive model of a thermal storage which is charged by a heat pump and used for domestic hot water supply. The model is used for smart grid control purposes and requires measurement signals of flow and temperature at the inlet and outlet of the storage to determine charged and discharged thermal energy, and electrical energy consumption of the heat pump. The paper reviews possible simulation models and describes a predictive model for the state of charge and for the heat pump power consumption during charging based on experimental data. Simulations are carried out and results are compared with experiments. The model is applied in a case of domestic smart energy control for which results are shown.
