However, solar power plants need extensive ground areas, which are a significant constraint. This restriction may be overcome if the panels are positioned on bodies of water. From this standpoint, the idea of Floating photovoltaic system installed in water bodies such as natural lakes or dams’ reservoirs was emerged, which provides advantages, the most important of which is an increase in production capacity as a result of the low temperature of the panel.in this search examined the possibility of floating PV systems for Benghazi Libya's Great Omar al-Mukhtar reservoir and was then compared to the same system but on the land. The architecture of the two PV systems was planned with the optimum tilt angle and photovoltaic spacing between the two systems in mind. The National Renewable Energy Laboratory (USA) System Advisor Model (SAM) was utilized to perform energy simulations based on meteorological data and system architecture. The findings showed that the planned floating PV system has risen by 4.16 percent over the ground PV system.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121417616","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}

Through enabling new paths for currents, shaded panels have less impact on blocking higher currents from series connected PV modules. This ultimately results in harvesting more power from partially shaded PV units. Unfortunately, the number of required DPP converters increases linearly with the number of series PV units. To address this challenge, this paper investigates the possibility of reconfiguring DPP converters reducing the number of needed converters. Instead of using a complete set of DPP converters, reconfiguring DPP converters could substantially reduce the number of needed converters. The used DPP converters will be connected to shaded units and reconfigured online with changes in shadings to reduce the mismatch power losses. Validation and verification through simulation is conducted to demonstration the effectiveness of the proposed idea.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121587180","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 case of microchannel is investigated using a mesoscopic numerical analysis. The nanofluid flow is driven along the microchannel by a co- flow at the inlet. Near the top cold wall the flow is induced by a constant velocity (Uin) and hot temperature (TH) but near the bottom heated wall the nanoliquid is driven by a constant velocity (Uin/4) and a cold temperature (TC). The slip velocity and the temperature jump conditions are imposed to the walls. Lattice Boltzmann method was used to solve the obtained governing equation system by means of the SRT-BGK model. Attention was focused on the influence of the emerging input parameters such as Knudsen number (Kn), Reynolds number (Re), nanoparticles diameter (Dp) and volume fraction (Vf) on the heat transfer enhancement and entropy generation minimization throughout this paper. Correlations of heat transfer enhancement and volumetric entropy have been inscribed based on response surface methodology.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122491920","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 purpose of this paper is to design and optimize a standalone hybrid energy system to satisfy the electricity demand for a remote drilling site in Adrar province located in the South of Algeria. To cure the problem of intermittence of the solar and wind sources, a hydrogen-based set up is appended to the hybrid renewable energy system.

Differential Power Processing (DPP) has been found effective in eliminating the impact of partial shading without adding extra power losses. They provide an effective alternative to distributed converters that require processing the entire extracted power scarifying the efficiency. This paper proposes a DPP structure that eliminates the needed voltage sensors for extracting the maximum power tracking. Instead of measuring the power of each individual PV submodule for tracking the maximum power, the proposed approach relies on maximizing the module current participating in eliminating the voltage measurements. Since the voltage of the module’s output is controlled by the output controller and can be considered constant to the faster inner controllers, operating the DPP converters to maximize the current should is demonstrated to maximize the power of the submodules. The effectiveness of the proposed structure is validated by simulation through Simulink under variety of shading scenarios.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130270985","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}

It determines the amount of radiation incident on PV panels surfaces, thus it is required for an economic evaluation of solar PV systems. For this reason, this study aims to estimate the optimum tilt angle of solar PV panels to exploit the maximum daily solar radiation on the inclined surface. The analysis was achieved based on measured data recorded in four cities of Libya. The optimum tilt angle was determined by changing the angle of surface from 0° up to 90° with the 1° resolution and searching for the maximum value of the corresponding daily total solar radiation. In addition, Six empirical models were established to estimate the optimum tilt angle of PV panels. Their empirical coefficients were determined using non-linear regression technique. The models accuracies were evaluated using statistical criteria such as mean bias error, MBE, root mean square error, RMSE, and correlation coefficient, R. A combined statistical indicator, CSI, has been developed to assess and rank the performance of models. The presented results showed that the optimum tilt angle in the four studied sites varied from 0° to 59° throughout the year, it increased during the winter and decreased during the summer. The results also showed that both third-order polynomial and Fourier model presented the best efficiency in estimating optimum tilt angle with R = 0.9943.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114504923","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}
