This study focuses on the thermal performance simulation of the CSERS administrative building. It proposed the integration of shading elements on the south façade of the building to enhance thermal comfort for office occupants. These shading elements incorporate photovoltaic cells, displaying the potential of utilizing photovoltaic in external shading devices. The main objective of this approach is effectively address issues related to high internal temperatures and excessive solar radiation exposure. Furthermore, it ensures the preservation of key functions of the building envelope, such as thermal insulation, provision of natural lighting, and prevention of internal thermal glare. Comparative analysis is conducted between the building equipped with shading devices and the one without, with a focus on measuring the total electrical energy generated by the photovoltaic panels. Simulation programs such as SketchUp and EnergyPlus are utilized for this purpose. The results of the simulations reveal that strategically designed shading on south-facing windows leads to 17.15% reduction in annual heat gains transmitted to the building. In addition, the integration of photovoltaic shading devices demonstrates outstanding performance characteristics, contributing a productive capacity of around 5916.388 MW/h to the building. This integration effectively harnesses solar energy to improve the indoor environment of the building.

Over the past decade, transportation electrification has emerged as a pivotal focus of the article. Electric vehicles (EVs) have progressively gained traction in the market, displacing conventional internal combustion engine vehicles. This surge in EV popularity has led to a corresponding increase in the number of charging stations, thereby significantly influencing the power grid (PG). Various charging strategies and grid integration approaches are being devised to mitigate the potential negative impacts of EV charging while optimizing the advantages of integrating EVs with the grid. This paper provides a comprehensive overview of the current state of the EV market, standards, charging infrastructure, and the PG’s response to the impact of EV charging. The article provides a comprehensive assessment of how forthcoming advancements in EV technology, including connected vehicles, autonomous driving, and shared mobility, will intricately influence the integration of EVs with the PG. Ultimately, the article concludes by meticulously analyzing and summarizing both the challenges and recommendations pertinent to the prospective expansion of EV charging infrastructure and grid integration. The proliferation of venture capital investments in nascent start-up ventures specializing in EV and battery technologies has experienced a pronounced surge, reaching an impressive sum of nearly USD 2.1 billion in 2022. This notable increase represents a substantial uptick of 30% compared to the figures recorded in 2021. Furthermore, these investments have been directed towards two key areas: advancements in battery technology and the acquisition of critical minerals. This discernible shift in investment trends underscores the growing recognition of the strategic importance and potential profitability associated with innovations in EV and battery technologies. In 2022, global expenditures on EVs surpassed USD 425 billion, marking a substantial 50% increase compared to the previous year, 2021. Remarkably, a mere 10% of these expenditures can be attributed to governmental support, with the bulk stemming from consumer investments.

Solar energy has a significant role in meeting rising energy demand while reducing environmental impact. Solar radiation and temperature are important factors on which PV energy production depends, but its optimal operation point is influenced by variations in the aforementioned environmental factors. The nonlinear behavior of the solar system and the variable nature of environmental conditions make determining the optimal operation point difficult. To overcome these difficulties, maximum power point tracking (MPPT) finding techniques are used to extract the optimal power from the photovoltaic energy system. The behavior of MPPT varies for different weather conditions, such as partial shading conditions (PSC), and uniform irradiance conditions. Conventional techniques are simple, quick, and efficient for tracing the MPP quickly, but they are limited to uniform weather conditions. In addition, these techniques don't achieve the Global Maxima (GM) and mostly stay stuck at the Local Maxima (LM). The Meta-Heuristic techniques aid in finding the GM, but their primary disadvantage is that they take a longer time to trace the Global Maxima. This study addresses the problem by combining Cuckoo Search (CS) and Particle Swarm Optimization (PSO) algorithms, leading to a hybrid (CSPSO) technique to extract the global maximum (GM). To verify the effectiveness of the suggested technique, its performance is examined under three different irradiance patterns for different PV array configurations (such as 3S and 4S3P) through MATLAB simulation. The outcomes of CSPSO are compared with the prior well-known Meta-Heuristic techniques such as Cuckoo Search (CS), Particle Swarm Optimization (PSO), and Crow Search Algorithm (CSA). The results show the suggested technique excels over other techniques in terms of accuracy, tracking efficiency, and tracking speed. The suggested technique is capable of tracking GMPP with an average efficiency of 99.925% and an average tracking time of 0.13 s in all shading patterns studied.

Enhancing photoconversion efficiency in a solar cell with the composition "glass/Mo/CUSbS3/ Sb2S3/CdS/i:ZnO/AL:ZnO" by varying the thickness of the absorption layer (Sb2S3) and adding a secondary absorption layer was performed. The thickness of the original absorption layer (Sb2S3) was gradually increased from (1 µm) to (3.5 µm). The best efficiency (23.14%) and filling factor (87.52%) were achieved with an absorption layer thickness of 3.5 µm. This indicates that a thicker absorption layer can enhance efficiency. A secondary absorption layer was introduced between the original absorption layer and the reflection layer. Several materials were considered for this secondary absorption layer, including MAPbI3, Sb2Se3, CZTS, and CZTSe. The best-performing secondary absorption layer was found to be Sb2Se3. The solar cell structure, after combining it with the best reflection layer (CUSbS3) and the optimized thickness for the original absorption layer (3.5 µm), was established as "glass/Mo/CUSbS3/Sb2Se3/Sb2S3/CdS/i:ZnO/Al:ZnO". The optimized solar cell configuration yielded the best conversion efficiency (27.01%) and a high filling factor (85.12%). These results highlight the significance of layer thickness and the addition of secondary absorption layers in enhancing the solar cell efficiency. The final configuration demonstrates substantial improvements in efficiency and suggests that thoughtful design and material choices can lead to more efficient photovoltaic devices.

Initially the concept of a DC nanogrid was focused on supplying power to individual homes. Techno-economic advances in photovoltaic (PV) technology have enabled solar PV stand-alone nanogrids to power individual devices using device-specific architectures. To reduce costs and increase accessibility for a wider range of people, a modular open-source system is needed to cover all applications at once. This article introduces a modular PV-powered nanogrid system, consisting of a do it yourself (DIY) PV system with batteries to allow for off-grid power. The resultant open-source modular DC nanogrid can deliver DC power to loads of different voltage levels, which is possible because of the efficient and parametric energy management system (EMS) that selects modes of operation for the grid based on DC bus voltage and state of charge of batteries. Simulation results verify the coordination between the EMS and the PV-battery system under varying PV power generation and load conditions. This EMS has potential to enable easy personalization of a vast area of applications and expand appropriate technology for isolated communities. A thorough stability analysis has been conducted, leading to the development of an LQR (Linear Quadratic Regulator) controller as a replacement for the conventional PI (Proportional - Integral) controllers for better transient stability of the system.

the world is currently facing energy-related challenges due to the cost and pollution of non-renewable energy sources and the increasing power demand from renewable energy sources. Green hydrogen is a promising solution in Libya for converting renewable energy into usable fuel. This paper covers the types of hydrogen, its features, preparation methods, and uses. Green hydrogen production is still limited in the world due to safety requirements because hydrogen has a relatively low ignition temperature and an extensive ignition range and is considered a hazardous element, the lack of infrastructure in Libya, as well as the high cost of production currently. However, the production costs of one megawatt of green hydrogen and fossil fuels are insignificant. This suggests that electricity production from green hydrogen could become an economic competitor to fossil fuels in Libya. This is due to the cost of adding renewable energy to the public electricity grid. Also, the production of gray hydrogen is possible in Libya because of oil through the installation of systems for converting methane gas and capturing carbon dioxide gas.

Since the Kyoto Protocol came into effect on Feb 16, 2005, the Clean Development Mechanism (CDM) has experienced significant global growth. This mechanism enables developing countries to actively engage in combating climate change by implementing projects aimed at reducing Greenhouse Gas Emissions (GGEs). In 2010, Libya established the Commission of the Designated National Authority (DNA) to oversee the implementation of the CDM. This move was made as part of Libya's efforts to develop a range of projects that qualify for CDM and contribute to reducing GGEs. The main motivation for conducting this study was the absence of Libya's involvement in global-level CDM projects, as evidenced by the United Nations Framework Convention on Climate Change (UNFCCC) annual reports. Additionally, the failure to recognize the significance of CDM in influencing decisions regarding investments in wind energy. This work aims to investigate the use of CDM in Dernah wind farm (I) project (Libya). The study used a suitable CDM methodology, AM0019 with the appropriate tool (03-V3), calculated as CO2 reductions and Certified Emission Reductions (CERs). The results of CDM analysis are as follows: CO2 reductions = 362,201.82 tCO2e/year and CERs for the first ten years of the age of the proposed wind farm (Dernah Wind Farm (ɪ)) (CERs10y) = 1,687,898,590 LD (320,838,371.8 €) for the first ten years, likewise CERs20y= 3,375,797,180 LD (641,676,743.5 €) during the entire life (20 years) of the proposed wind farm. Based on these results, it can be concluded that the project will be highly cost-effective, this will lead to lower electricity prices for consumers and higher profits for the project owners. Therefore, registering wind energy projects as CDM projects and earning CERs is the most practical way to promote wind energy. The findings of this study could be valuable for policy makers and project developers who are interested in CDM wind projects.

The main motivation for conducting this study was the absence of Libya's involvement in global-level CDM projects, as evidenced by the United Nations Framework Convention on Climate Change (UNFCCC) annual reports. Additionally, the failure to recognize the significance of CDM in influencing decisions regarding investments in wind energy. This work aims to investigate the use of CDM in Dernah wind farm (I) project (Libya). The study used a suitable CDM methodology, AM0019 with the appropriate tool (03-V3), calculated as CO2 reductions and Certified Emission Reductions (CERs). \u0000The results of CDM analysis are as follows: CO2 reductions = 362,201.82 tCO2e/year and CERs for the first ten years of the age of the proposed wind farm (Dernah Wind Farm (ɪ)) (CERs10y) = 1,687,898,590 LD (320,838,371.8 €) for the first ten years, likewise CERs20y= 3,375,797,180 LD (641,676,743.5 €) during the entire life (20 years) of the proposed wind farm. Based on these results, it can be concluded that the project will be highly cost-effective, this will lead to lower electricity prices for consumers and higher profits for the project owners. Therefore, registering wind energy projects as CDM projects and earning CERs is the most practical way to promote wind energy. The findings of this study could be valuable for policy makers and project developers who are interested in CDM wind projects.","PeriodicalId":232564,"journal":{"name":"Solar Energy and Sustainable Development journal","volume":"250 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139011498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal of this study is to design optimize and design a hybrid wind/PV solar power system to provide the premises of the Libyan Center for Solar Energy Research Center (LCSERS) with the required energy and investigates its technical and economic feasibility. HOMER simulation program is used to design the off-grid and assess the feasible solution and economic cost. The power systems are optimized based on the electricity load, climatic data sources, the economics of the power components, and other parameters in which the total Net Present Cost (NPC) must be minimized to select an economically feasible power system. Moreover, other parameters like a renewable fraction, capacity shortage, Cost of Energy (COE), and excess electricity, were also considered to check the technical capability. Sensitivity analysis of the most influential variables has been considered in four scenarios of capacity shortage. In the off-grid hybrid system, the best option is the fourth scenario, where the capacity shortage is 5% of the 60,385.6 kWh/yr electric load, peaking at 43.45 kw, because the lowest COE is 0.222 $ and the NPC is 168,173 $. The system consists of a 20 kW PV, one turbine of 25 kW, and 72 Hoppecke batteries of 1500.Ah each. The annual share of wind energy was 77%, and solar energy was 22.9%. The estimated excess of electricity was 58.3%.
