The pump is employed to irrigate wheat and maize crops in a one-feddan farm by adopting the actual well depth and crop water requirement in the proposed locations. Furthermore, the total power of solar modules required to operate this pump is computed to reveal the auxiliary power needed for these crops at the proposed locations during their irrigation season. At the introduced weather conditions, an economic analysis is conducted to examine the feasibility of the solar powered pump versus that operated by traditional diesel generator. The results reveal that the net generated power via the PV panels to operate a pump used to irrigate wheat crop is 325, 495 and 17 kW and for maize crop is 1786, 1767 and 266 kW in Aswan, Alexandria and Giza cities, respectively. In Alexandria, Giza, and Aswan cities, utilizing solar PV panels as a power source for the pump used to irrigate wheat crop has proven its economic feasibility as it is expected to dramatically reduce the total cost by around 49, 46, and 76%, respectively and for maize crop cost is reduced by 47, 48 and 66% in the same locations compared to diesel generators.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67638815","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}

Techno economic assessment and analysis were done by using the HomerPro software. Many factors were considered such as the weather conditions, availability of different renewable energy resources, life security, and economic factors. The weather conditions were found having limited impacts on the overall performance of the proposed system because of the successful technical integration of the wind and solar weather conditions during the summer period. Using the real load data for 2019 and 2020, at a peak load of 500 kW and an annual load demand of 2350 MWh, different hybrid generation solar, wind, diesel generator and storage battery configurations were examined for the best optimum sizing, minimum cost, and most stable system for 25 years period. The techno economic analysis results proved that the proposed system could run with a 1004 kW PV solar system, 160 kW wind turbine with a contribution of 580 diesel electricity generator and storage of 1478 kWh yearly. The proposed system is expected to produce an annual electricity production of 3,548 MWh/year, of which around 56.6% (2,007 MWh/year) will produced by the solar PV panels at LCOE of $0.234 per kWh.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135214197","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 PVT-DPSAH comprises a glass cover, absorber plate (PV), PCM capsules, and back plate. The current study uses COMSOL Multiphysics software to perform a computational fluid dynamics (CFD) analysis of a novel PVT-DPSAH with vertical cylindrical PCM capsules in the second channel. To solve the differential equations in the 3D computational domain, the finite element method (FEM) is employed. This study uses the high Reynolds (Re) number and ?-? turbulent flow model with enhanced wall functions. The impact of varying solar irradiance levels (500- 800 W/m2) on the performance of PVT-DPSAH, with mass flow rates ranging from 0.011 kg/s to 0.065 kg/s, is investigated. The optimum mass flow rate (?) was found to be 0.037 kg/s at solar irradiances ranging from 500 W/m2 to 800 W/m2, with average thermal efficiencies, electrical efficiencies, and fluid output temperatures of 60.7% to 63.4%, 11.25% to 11.02% and 42.96 oC to 49.54 oC, respectively. PVT collector's maximum combined efficiency was 84.12% at solar irradiance of 800 W/m2 with the ? of 0.065 kg/s. This study identified RT-47 paraffin-wax-PCM as the best option for the PVT-DPSAH based on the PCM's thermal distribution and melting temperature.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135214206","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}

This serves as a clear impetus for universities to transition to renewable energy technologies, which offer the advantages of cost-effective operation and minimal environmental footprint. This paper presents the design of a grid-connected photovoltaic (PV) system with battery storage to fulfil the electricity consumption needs of Universiti Teknikal Malaysia Melaka (UTeM) main campus. The objective is to reduce grid dependency, lower electricity costs, and minimize carbon dioxide (CO 2 ) emissions. The system was modelled and simulated using DIgSILENT software. Load demand and energy consumption data were extracted from the Tenaga Nasional Berhad (TNB) electricity bill, while the PV profile and irradiance data were obtained from the UTeM solar laboratory. Based on the findings, it has been determined that a 12 MWp PV system, coupled with a 25.8 MWh battery, represents the optimal solution for satisfying the total electricity demand of UTeM's main campus. The installation of this system is projected to result in estimated monthly electricity bill savings of MYR 422,611 for UTeM. Furthermore, the proposed system offers a significant environmental benefit by potentially reducing CO 2 emissions by up to 1,507,520 kg per month. The findings of this study can inform decision-makers in implementing a cost-effective and environmentally friendly energy solution for UTeM's main campus.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135214216","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}

Agricultural residue, which consists primarily of organic components, can be exploited effectively and sustainably to generate biogas by digesting anaerobically. This paper proposes a microgrid (MG) system for dependable electricity in rural areas and effective utilization of existing renewable resources. A complete techno-economic analysis was conducted on constructing an MG system based on solar and biomass energy. Two MG systems delivered reliable rural electrification , MG-I with solar (PV) and MG-I with its isolated PV system, and MG-II with its biomass-based generating units, unstable grid, biomass, and batteries. The investigation includes several performance evaluation criteria: component costs, inflation rate, project viability, generation responses, emissions, and fuel prices. This research shows that grid-connected MG systems can provide more reliable electricity at lower prices than island-based MG systems. In addition, w ith the efficient use of plentiful biomass resources, the proposed MG power system lowers atmospheric pollution.","PeriodicalId":14385,"journal":{"name":"International Journal of Renewable Energy Research","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135214492","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}
