All over the world, researchers keep looking for the best layouts of wind parks to maximize captured energy. To design wind farms suitably, forecast their performance, and understand the strain loads of wind turbines, there is a persistent need to catch a perfect wake model. Wind turbine wakes are one of the most vital factors in the meteorology of wind power due to reducing the power production and the necessity to raise the downstream capacity of wind turbines. This study is divided into two main aspects: firstly, enhancing the optimal layout for the wind turbines at a farm using Marine Predators Algorithm (MPA). The Jensen wake model is applied to get the extracted power for each turbine, which is one of the mutual analytic models used to reach the optimized layout. By comparing the performance of the proposed algorithm with the previous studies achieved by several techniques, the obtained results revealed that the MPA achieves promising results. Secondly, the proposed algorithm is applied for four sites in Egypt as the fraction of occurrence for the selected locations has been adequately calculated using wind speed over five years.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67638331","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}

One of the most effective water desalination techniques is solar desalination. Solar desalination works better under higher temperatures of water as it increases the evaporation and desalination rates. Evacuated tube solar collector (ETSC) presents an advantage as a solar water heater in medium temperature ranges and is suitable for solar desalination. The enhancement of its performance has been a hot topic in the last years due to its high efficiency at high temperatures. However, the techniques with which the ETSC implemented, differs in storage availability as in the all-water systems, good heat transfer as in the direct flow system. In the present research a novel technique combining the benefits of both all-water and direct flow systems is presented to increase the temperature of the heated water. The combined system considers the injection of the feed water inside the ETSC directly to make use of forced convection heat transfer and destruct the stagnation zone in the bottom of the tubes. Three water flow rates of 2, 4, 8 LPH were tested. The combined system achieved an enhancement in the thermal efficiency and the maximum temperature getting out from the ETSC by 27% and 14.7%, respectively, at a flow rate of 8 LPH. Moreover, the overall efficiency was enhanced by up to 27.3%, compared to all-water system. The economic study showed that the cost of heated water with the proposed system over the traditional system reaches 0.00195 $/kw.hr for 8 LPH extraction rate. Due to this increase in the system temperature, the proposed techniques can be applied for solar desalination. The numerical simulation results found to agree with the experimental results by 5.4% relative error.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135213722","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}

Long-lasting energy can be achieved by attenuating Greenhouse gas emissions. All over the world, Hybrid Renewable Energy Sources (HRES) appear as a vital element when it comes to cover the rapid growth of the energy demand. Moreover, renewable energy (RE) is an unaffordable response to the fight against unpredicted events such as the diseases, industries development, reliability of energy sources, added to the various directives related to produce sustainable electricity. Henceforth, it is crucial to optimize the various energy sources for satisfying the electrical demand. In particular, this paper aims to value the hybridization of optimization techniques to achieve a robust optimization. Photovoltaic (PV), and Battery Storage Systems (BSS) constitute the various RE sources in this work. The main goal was to simultaneously minimize the Deficit of power supply probability (DPSP) and maximize the BSS capacities. Particle Swarm Optimization (PSO), Grey Wolf Optimizer (GWO), and hybridization of both techniques are employed to proceed with the optimization. This study reveals the performance of hybrid optimization used for several configurations of loads. Indeed, the results show that the autonomous day of the BSS can reach 03 days, while the DPSP can decrease towards 1%. In this way, the HRES built up is more ecofriendly and autonomous. Furthermore, the proposed idea provides improved reliability and robustness of our system under various types of loads due to different climate scenario. The statistical analysis also carried on shows a good stability while doing hybridization of both techniques and a better efficiency in comparison to single techniques.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135214495","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}

For this reason, the energy needed in the houses should be kept at a minimum level without compromising the comfort conditions. In this study, passive steel house design was realized with the use of photovoltaic power systems and building materials. Firstly, rock wool, fibercement and XPS plate were studied as a building material suitable for passive steel house. Since rock wool is a non-combustible material and provides very good sound and heat insulation, it can be preferred. Due to the high compressive strength and moisture resistance, XPS plate is preferred on under the ground flooring. Fibercement boards are easily used as interior and exterior cladding in passive steel house. The designed passive steel house has an area of approximately 150 m 2 . Two passive steel house models are created. The passive steel house cost is 91,850$. Monocrystalline photovoltaic panels are sufficient to meet the energy needs of the passive house. Passive steel house is located in Istanbul and the global radiation value is approximately 1400 kWh/m 2 -year. Annual energy production of the monocrystallian panel is calculated as 18,893.5 kWh. The required installed power is calculated approximately 4 kW for connected to the grid and 5 kW for independent from the grid. 22 monocrystalline panels are used to meet the energy needs of the passive steel house. The cost of monocrystalline photovoltaic power system was calculated as 8,636$.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135214501","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}
