A Cost-Effective Thermal And Electrical Energy Storage Management Strategy For Smart Buildings

In smart residential buildings, variations in rooftop photovoltaic (PV) power causes a mismatch between generation and load demand. This paper deals with combined thermal and electrical energy systems, including a heat pump coupled with a thermal storage tank, rooftop PV modules, a battery energy storage system, and the electrical and thermal loads. An integrated home energy management system with optimal operation schedule is proposed to manage different resources based on time-of-use pricing tariff to minimize the operation cost of a smart building and reduce the mismatch between generation and load. Extensive simulation results show the cost benefits and effectiveness of the proposed combined thermal and electrical energy management strategy.
