Summary

The increasing availability and penetration of renewable energy sources poses new challenges to the power grid stability. To this purpose, advanced energy management strategies can be adopted to improve building energy flexibility, defined as the ability to manage the building according to grid requirements, climatic conditions and user needs. The management of Heat Pumps (HPs) coupled with energy storages through a proper supervisory control can largely contribute to effectively enhance flexibility. A prototype nZEB building was modelled along with its integrated PV generators, energy storages and HP with the aim of assessing the influence of various supervisory control strategies on the system performance. Two simple Rule Based Controls were used as baseline while two purpose-oriented Rule Based Controls were implemented and proposed in order to improve self-consumption and self-sufficiency and reduce the energy cost. Results proved that the system flexibility is greatly affected by the adopted control, and that carefully designed Rule Based Controls can effectively reach the set goals, namely the energy-saving-oriented strategy allowed to increase self-consumption by 14.64% and self-sufficiency by 13.79% with respect to the first baseline RBC, while the cost-oriented strategy resulted in a 53% cost reduction with respect to the same baseline.
