Solar energy is a fascinating green energy source. the most basic use of solar energy is to convert it into usable heat. Domestic hot water is the second-largest source of household electricity after lighting. The subject of this research is the thermosiphon theory of normal water circulation. An experimental setup and a computer program (POLYSUN) of a solar thermal system are presented in this work in Erbil city of Iraq. A four-person single-family house with a flat-plate solar thermosiphon water heating system and a water capacity of 200 L and also had a total surface area of 2 m 2 . All simulations are conducted with the collector tilt angles of 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, and 90° for the whole year. In January 2021, the experimental work was also taken out in Erbil. The optimum tilt angle of the solar collector is estimated to be close to 40o. the overall energy savings, solar fraction, and collector efficiency are 1284 kWh, 29.6%, and 37.9%, respectively, for the entire year. Polysun Software and the experimental setting of the solar thermal system were compared on the basis of electricity consumption.

Case study on demand side management‐based cost optimized battery integrated hybrid renewable energy system for remote rural electrification

et al. 2022

Power demand of isolated villages where on‐grid power supply is not economical can be met by standalone renewable energy system. Hybrid renewable energy system (HRES) considered in the current study involves photo‐voltaic, wind turbine, diesel generator, and battery. In the present study, the demand side energy management methods are used for energy management. The load shifting and strategic conservation methods are used. The energy management schemes are applied in the stage of load estimation. It is observed in the analysis that, the net present cost (NPC) of $55 263 is reduced to $34 009 with the application of demand side energy management strategies. The two control strategies, load‐following and predictive‐dispatch strategy are incorporated. The three types of batteries like lead‐acid, lithium‐ion, and zinc‐bromide are integrated, one at a time, for analysis. The analysis results in the optimal HRES configuration solution with the combination of both load shifting and strategic conservation techniques of demand side energy management. The NPC is reduced by 37% in comparison with the HRES without the application of energy management methods. The zinc‐bromide battery integrated HRES configuration through predictive dispatch control strategy with the application of demand side energy management schemes results in optimal solution for electrification of cluster of villages located in Uralagallu panchayat, Sagar Taluk, Shivamogga District, Karnataka, India. To the similar kind of geographical condition areas, the same HRES configuration with similar approach can be extended for electrification.

“…For the households, the application of DR strategies has been investigated by researchers to schedule the operation of: space heating systems [15], electric water heating systems [16], heat pumps [17], photovoltaics-battery systems [18], wind energy generation [19], solar hot water systems [20], washing machines, and dishwashers [21]. Various approaches have been used for modelling such as the Markovian model [22], game theory [23], the home energy management system (HEMS) model [24], mixed integer linear programing [25] and the ant colony optimisation algorithm [26].…”

Demand Response Model Development for Smart Households Using Time of Use Tariffs and Optimal Control—The Isle of Wight Energy Autonomous Community Case Study

et al. 2020

View full text Add to dashboard Cite

Residential variable energy price schemes can be made more effective with the use of a demand response (DR) strategy along with smart appliances. Using DR, the electricity bill of participating customers/households can be minimised, while pursuing other aims such as demand-shifting and maximising consumption of locally generated renewable-electricity. In this article, a two-stage optimization method is used to implement a price-based implicit DR scheme. The model considers a range of novel smart devices/technologies/schemes, connected to smart-meters and a local DR-Controller. A case study with various decarbonisation scenarios is used to analyse the effects of deploying the proposed DR-scheme in households located in the west area of the Isle of Wight (Southern United Kingdom). There are approximately 15,000 households, of which 3000 are not connected to the gas-network. Using a distribution network model along with a load flow software-tool, the secondary voltages and apparent-power through transformers at the relevant substations are computed. The results show that in summer, participating households could export up to 6.4 MW of power, which is 10% of installed large-scale photovoltaics (PV) capacity on the island. Average carbon dioxide equivalent (CO2e) reductions of 7.1 ktons/annum and a reduction in combined energy/transport fuel-bills of 60%/annum could be achieved by participating households.
