This paper presents a mathematical formulation to evaluate the operational mode of a residential energy hub model for assessing the possible level of local energy trading. Electricity and natural gas are the inputs of this energy hub that meet a typical house's electric and heat demands. Integrating renewable energy sources and energy storage systems streamlines the energy hub framework. A home load management (HLM) strategy is proposed to manage the energy consumption of responsive appliances. Solar panels and battery operation are coordinated with the household demand response to minimize the customer cost and maximize self-consumption. The main objective of this study is to reduce consumer costs by considering the hourly effects of time varying electric tariffs on energy hub optimization results. The presented results proved that the HLM application alone reduced the daily payment of customers by around 15% compared to those without HLM. The increased surplus energy may be a basis for local energy trading without grid involvement and is considered a viable option to further reduce customer payments. A novel approach is analyzed using TRNSYS software to identify real-time execution of household-level energy production and local trading potential. Furthermore, the contribution of HLM to energy sharing is investigated at the prosumer-consumer perspective. © 2024 The Authors}, keywords = {Housing; Renewable energy; Renewable energy; Energy trading; Energy trading; Electric load management; Renewable energies; Energy utilization; Sales; Electric energy storage; Energy hub; mathematical formulation; Power markets; local energy; Demand response programs; Energy infrastructures; Electric power plant loads; residential energy; demand response program; Energy hubs; Home load management; Home load management; Operational modes}, year = {2024}, eissn = {2352-4847}, pages = {1642-1658}, orcid-numbers = {Rana, Aqsa/0000-0002-2400-8256; Gróf, Gyula István/0000-0002-6359-768X} } @article{MTMT:34568870, title = {Prosumer potential assessment and techno-economic feasibility analysis of rural electrification}, url = {https://m2.mtmt.hu/api/publication/34568870}, author = {Rana, Aqsa and Gróf, Gyula István}, doi = {10.1016/j.ecmx.2024.100542}, journal-iso = {ENERGY CONVERS MANAG: X}, journal = {ENERGY CONVERSION AND MANAGEMENT: X}, volume = {22}, unique-id = {34568870}, issn = {2590-1745}, year = {2024}, orcid-numbers = {Rana, Aqsa/0000-0002-2400-8256; Gróf, Gyula István/0000-0002-6359-768X} } @article{MTMT:34568916, title = {Fejlődő országok hálózattal nem ellátott területeinek villamosítása megújuló energia bázison}, url = {https://m2.mtmt.hu/api/publication/34568916}, author = {Rana, Aqsa and Gróf, Gyula István}, journal-iso = {ENERGIAGAZDÁLKODÁS}, journal = {ENERGIAGAZDÁLKODÁS}, volume = {6}, unique-id = {34568916}, issn = {0021-0757}, year = {2023}, pages = {11-19}, orcid-numbers = {Rana, Aqsa/0000-0002-2400-8256; Gróf, Gyula István/0000-0002-6359-768X} } @article{MTMT:34023797, title = {Tanszékvezetők előszava}, url = {https://m2.mtmt.hu/api/publication/34023797}, author = {Imre, Attila and Bihari, Péter and Gróf, Gyula István and Penninger, Antal}, journal-iso = {ENERGIAGAZDÁLKODÁS}, journal = {ENERGIAGAZDÁLKODÁS}, volume = {64}, unique-id = {34023797}, issn = {0021-0757}, year = {2023}, pages = {2-2}, orcid-numbers = {Imre, Attila/0000-0003-4604-5899; Bihari, Péter/0000-0002-2757-2266; Gróf, Gyula István/0000-0002-6359-768X} } @article{MTMT:34189379, title = {Efficiency improvement of the solar chimneys by insertion of hanging metallic tubes in the collector: Experiment and computational fluid dynamics simulation}, url = {https://m2.mtmt.hu/api/publication/34189379}, author = {Rezaei, L. and Saeidi, Samrand and Sápi, András and Abdollahi, S.
