A small red brick house of 20×20×20 cm3 was used for the test, and throughout the experiment, the temperature was recorded every minute at the center of each wall facing the four cardinal points (East, West, North, and South) for 24 h (day and night). A digital acquisition device based on an Arduino board was realized to record the temperature on different days at the end of June, July, August, and the beginning of September. Only when solar radiation is present during the day can the influence of the walls' orientation be detected. The temperature of the walls remains nearly constant at night and drops from sunset to daybreak. The wall facing east is the hottest in the morning during the summer. The west-facing wall, on the other hand, is the coolest, especially in the morning. In the early summer, the west-facing wall is the hottest in the afternoon. It will, however, be replaced by the south wall at the end of the season. The temperature of building walls is significantly affected by the sun's daily and annual trajectory.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"11 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":"114108980","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}

Telecommunication systems should be emphasized because of their impact on development. Consequently, the energy supply plays an important part of any communication system. It is essential to select the power source option that has the low cost and long life. This paper presents a practical design and implementation of an on-grid PV system for the local telecommunication companies in Benghazi, the companies started using solar-powered systems at many of their sites in order to guarantee continuous services. The study starts by classifying the sites according to the load size into four types: 200W, 500W, 700W and 1000W and the PV system components sizing are evaluated for each type. The hybrid system option has been chosen to guarantee continuous power supply to the load. It is concluded that the use of photovoltaic systems at telecommunication sites accomplished not just technological success but also an economical one. This study can be used for research, teaching, as well as for the telecommunication companies as an initial assessment for future grid connected PV systems installation.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"247 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":"122987982","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}

Considering that each method has its advantages and disadvantages according to the application and operating conditions, and monitoring the batteries in their second life is of special importance because it is required to integrate with the battery management system to balance cells, diagnose faults and prevent overheating. Therefore, the estimation method developed in this study, by incorporating artificial neural network method and Kalman filter method with fine-tuning of the filtering process using Coulomb counting, provides a solution for more accurate online monitoring of these batteries.

However, the wind resource is inherently unpredictable, bringing important challenges to the stable and safe operation of the power grid. In this context, various computational and statistical approaches have been reported in the literature to perform short-term forecasting of wind power generation, and more efficient strategies are still demanded. In this paper, a hybrid framework that includes a statistical pre-processing stage with an enhanced deep learning (DL)-based strategy is proposed to address the limitations of reported forecasting methodologies to predict multi-seasonal wind power time series. The integrated approach applies a suitable transformation to obtain a normal distribution of data and removes multiple seasonalities in wind power time series. Subsequently, it supplements a set of stacked Long Short Term Memory (LSTM) Recurrent Neural Network (RNN) models for each month of the year. The proposed approach is validated using real hourly wind power data from the Spanish electricity market for the period 2008-2019. A comparative analysis with a well-established DL-based model shows the superior performance of the proposed forecasting method. The experimental evaluation is conducted for 1-3 hours ahead of wind power predictions.

In solar energy rich countries, like Libya, this can be significantly provided by solar energy technologies. Dairy factories involve a number of processes requiring heat at different temperatures. Some processes even require steam at high temperatures. Pasteurization, sterilization, cleaning, washing, and evaporation are some of the operations in dairy processing plants. Concentrated solar power plants can provide such high temperatures using a number of technologies, specifically parabolic trough reflectors, linear Fresnel reflectors, parabolic dish, and the central receiver with a heliostat field. Libya is located in the sun belt and is pleasant with high levels of sun radiation. This paper investigates the techno-economic feasibility of a concentrated solar power plant utilizing linear Fresnel reflectors technology to provide heat for the pasteurizing process at a proposed milk processing diary. A production rate of 100,000 liters per day of milk was assumed. All of the parameters involved in the design process, such as the available area, solar energy available at the location, energy demand of the process, inlet and outlet temperatures, energy storage requirement, and cost per unit of electricity, were fed to the Ressspi platform, a solar simulator for industrial processes. Results showed that the system is highly feasible in terms of technical as well as economic aspects. The heat generated by the solar plant was 1260661.4 kWh, while that consumed by the process was 1321636.8 kWh and that represents 95.4% of the energy needed for the process. The solar utilization factor is 77.1% as a result of energy lost due to defocusing of the Fresnel reflectors. The payback period of the project was found to be 5 years with an internal rate of return of 23.88% and a levelized cost of energy of 0.03228 €/kWh.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"151 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":"122967107","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}
