Authors:Kiswendsida Elias Ouedraogo; Pınar Oğuz Ekim, Erhan Demirok Abstract: This study focuses on the optimization of power bills for a house equipped with a grid-tie solar PV-battery system. Rather than adhering to conventional load scheduling practices or minimizing grid power usage at each time interval, a novel approach is adopted wherein the optimization is performed for the entire 24-hour period simultaneously. By directly incorporating time-of-use rates into the cost function, an absolute optimal solution is attained. The findings indicate that compared to single time step optimization, the proposed method results in a reduction of the power bill ranging from 6% to 10%, depending on load-generation variations. Furthermore, if the utility or government enforces the summer tariff consistently throughout the year, the savings escalate to a range of 15% to 22%. Introducing a more intelligent tariff structure can thus serve as an effective means to expedite the transition towards renewable energy by incentivizing individual investments in solar PV, battery systems, and smart home energy management.

Authors:Akpaduado John; Joseph Oyekale Abstract: Abstract In the modern world, solar energy is one of the most mature renewable energy resources for electricity generation. Because of the growing interest in green energy and CO2 reduction, concentrated power technologies have gained prominence all over the world. Several parabolic trough power plants are currently operational in various parts of the world. However, despite the region's favorable weather conditions, Nigeria and Sub-Saharan Africa have yet to adopt this technology. To galvanize the integration of solar energy into the energy infrastructure in Nigeria, technical and economic feasibility studies are required. This paper presents a techno-economic viability assessment of a 25 MW Parabolic Trough solar thermal power plant for electricity generation in Effurun-Warri, Nigeria. The System Advisor Model (SAM) software was used for the analysis, based on the validated technical and financial models inbuilt into the software. Results showed that the plant is technically feasible in Effurun-Warri with a capacity factor of over 35%, which compares favourably with other similar plants across the globe. However, the levelized cost of electricity (LCOE) of 11.87 cents/kWh obtained is significantly higher than the subsidized cost of electricity in the country, by about 99%, leading to a negative net present value of the project. To improve cost, optimized design parameters of the plant should be adopted for performance simulation in the SAM software. PubDate: Fri, 29 Dec 2023 00:00:00 +030
Authors:Ekrem Alagoz Abstract: This review article explores the implications of electrifying the transportation sector for the oil and gas industry. The current state of the transportation sector and the role of oil and gas in it are discussed, followed by an introduction to the concept of electrification and its potential benefits and challenges. The article analyzes the potential impacts of electrification on the oil and gas industry, including changes in demand for oil and gas and opportunities for investing in renewable energy and developing new technologies. Several case studies of companies in the oil and gas industry that are adapting to the transition to electrification are presented, including those investing in renewable energy and developing electric vehicle charging infrastructure. The role of government policies and regulations in the transition to electrification is also discussed, including incentives for electric vehicles and renewable energy and their potential impact on the oil and gas industry. The article concludes with a summary of the potential implications of electrifying the transportation sector for the oil and gas industry, along with recommendations for how companies in the oil and gas industry can adapt to the transition to electrification. Overall, the article provides a comprehensive overview of the electrification of the transportation sector and its impact on the oil and gas industry, offering insights and recommendations for industry stakeholders.
