“…Second, MHEL control actions are conducted in the optimization to achieve accurate control. Generally, the related research in such MHEL scenarios can be seen in studies by Nordgård-Hansen et al (2022) and the Ma et al (2021). Among them, Nordgård-Hansen et al (2022) established an investment and operation model for RPV and GSHP systems in a single house in Norway.…”

“…1) The energy structure described by Nordgård-Hansen et al (2022) is extended by installing solar accumulators and GSHPs, which lead to a more complex and energy-coupled scenario, and the residential energy use pattern is more flexible with the participation of EVs. 2) A joint DA and RT energy dispatching strategy is proposed, in which a stochastic scheduling model is established and the expected carbon emission cost is minimized in different and uncertain scenarios.…”

Clean energy utilization is important for the improvement of energy structure. At present, photothermal and electrothermal conversion technologies are becoming increasingly applied in many homes, which can thus be regarded as green residences. To meet the heating demand of green residences, solar hot water systems and electricity-to-heat (E2H) conversion devices, such as ground source heat pumps electric heating stoves and electric water heaters are widely installed to provide a clean form of heat. Besides, common loads, such as lighting, washing, and electric vehicles are daily loads in green residences. The above electric and thermal loads are regarded as multi-energy heterogeneous loads MEHLs can be used to decarbonize green residences by optimizing energy dispatch through flexible control. In this study, a novel energy structure of green residences was extended through the combination of SHWs, E2H, GSHPs, and EVs, as well as rooftop photovoltaic systems. Then, to minimize carbon emissions, a residential energy dispatching model was designed from day-ahead and real-time scales and a low-carbon-oriented multi-energy heterogeneous loads coordinated control strategy was proposed. Finally, to mitigate the residents’ loss of comfort caused by MEHL control, the indoor environment and water tank temperatures and the state of charge of EVs were regarded as special constraints. The simulation revealed that the proposed strategy can reduce carbon emissions by 33.07% and meet the basic demand for residential heat and electricity. Additionally, the strategy has good applicability for decarbonizing green residences.

“…The study revealed that the thermal efficiency of the systems was 6.6% higher than geothermal source systems. Nordgard-hansen et al [9] proposed a mixed integer linear programming model to optimize the scale and operation of the system which they designed. The study indicated that the GSHP was conducive to improving the sustainable use of the system, and the specific operational mode of the device was related to the current on-grid price.…”

Regional integrated heating using renewable energy is an efficient way to achieve the target of carbon emission reduction. Based on geothermal sources, air source heat pumps, and inter-seasonal energy storage technologies, a multi-source integrated regional heating system is proposed, which can meet the requirement of heating in buildings. With a residential community with an area of 35700 m2 as the study case, the models of geothermal source heat pump and air source heat pumps are constructed. Next, the energy performance and environmental performance of the integrated district heating system are analyzed. The study manifests that the multi-source central heating system reduces the energy consumption by 45.73% in comparison with the tranditional boiler solution, and the CO2 emission is reduced by 787.83 tCO2. The multi-source heat pump system can achieve social benefits, with the help of reasonable dispatching between the source and load sides, and the contribution of renewable energy. The long-term stable operation of the energy system can be achieved. The study provides a theoretical reference for the application of the conventional energy systems combined with geothermal energy.
