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 LA - English DB - MTMT ER - TY - JOUR AU - Rana, Aqsa AU - Gróf, Gyula István TI - Assessment of prosumer-based energy system for rural areas by using TRNSYS software JF - CLEANER ENERGY SYSTEMS J2 - CLEANER ENERGY SYSTEMS VL - 8 PY - 2024 PG - 10 SN - 2772-7831 DO - 10.1016/j.cles.2024.100110 UR - https://m2.mtmt.hu/api/publication/34751430 ID - 34751430 AB - The prosumers are the new performers progressing towards a low-carbon future. Renewable-based power generation is essential, even in rural areas, to pave a path toward sustainable development. This study establishes a simulation model for two identical residential buildings to assess the prosumer's impact on future local (standalone) energy systems. According to the climate condition of Pakistan, the technical, economic, and environmental performance of the standalone system is evaluated using TRNSYS software. Assumptions and modeling of different components, photovoltaic (PV) panels, and batteries are also discussed. This study provides the starting point of a real-time framework of energy trade between two rural houses connected with a common microgrid. Both houses are medium-sized family houses with almost identical electricity demands. One house has PV mounted on the rooftop, with the battery as an optimal energy storage option. Attention is given to peak demand management and surplus energy during enough production hours. A dynamic energy management approach between two buildings is proposed based on TRNSYS and blockchain. Simulation results show that the real-time implementation of local energy production and energy trading at the household level facilitates achieving the dual benefits of reducing consumer costs and maximizing self-consumption. © 2024 The Author(s) LA - English DB - MTMT ER - TY - JOUR AU - Rana, Aqsa AU - Gróf, Gyula István TI - Prosumer potential assessment and techno-economic feasibility analysis of rural electrification JF - ENERGY CONVERSION AND MANAGEMENT: X J2 - ENERGY CONVERS MANAG: X VL - 22 PY - 2024 PG - 11 SN - 2590-1745 DO - 10.1016/j.ecmx.2024.100542 UR - https://m2.mtmt.hu/api/publication/35218256 ID - 35218256 N1 - The research is part of the Ph.D. The study is supported by TEMPUS in the frame of Stipendium Hungaricum. AB - The expansion of the industrial sector and the continuous increase in population are the reasons for the ever-increasing demand for electricity, which directly burdens the central grid. Absence and remoteness from the central grid make off-grid power generation the most reliable source of electricity to meet the needs of peripheral areas. Electrification of remote areas through decentralized generation using renewable energy sources has emerged as a low-cost and practically viable solution. Domestic-level energy trading makes the system more cost-effective. This study develops a hybrid energy model consisting of PV and diesel generators to electrify a remote village, considering the feasibility analysis of consumer-prosumer-based energy trading potential. First, resource evaluation and total load demand are estimated at the selected site, then system sizing optimization and techno-economic feasibility are evaluated using HOMER Pro software. Based on the optimized system, a new system is proposed and developed using HOMER Pro software to investigate the energy trading potential. Economic rationality is checked using the economic parameters of net present cost, levelized cost of electricity, initial capital, and operation and maintenance cost of the system. A sensitivity analysis is performed further to evaluate the system's feasibility under different conditions. This study fills the energy trading sector gap by providing a more efficient and cost-effective simulation-based study. The results show that the proposed system has a 22 % lower net present cost, 66 % lower levelized cost of electricity, 25.5 % lower operation and maintenance cost, and 4.36 % lower initial cost.
