The least square method is used to establish the models and determine their empirical coefficients. In order to evaluate the performance of the established models, three statistical error tests were introduced, root mean square error, RMSE, mean absolute percentage error, MAPE, and correlation coefficient, R2. The obtained results indicated that the weather condition is fair during May-September, and scattered clouds during the other months. The results also indicated that the sunshine duration-based quadratic model presented the best efficiency for estimating the monthly average of daily global solar radiation on a horizontal surface, where it had the highest value of correlation coefficient, and the smallest values of MAPE and RMSE of 0.93, 2.8049, and 0.0195 kWh⁄m2 ⁄day, respectively.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129592819","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 first contribution of this work consists in introducing an Integral Sliding Mode Speed Controller (ISMSC) to the Direct Torque Control (DTC) of the induction motor, in order to enhance the speed regulation loop and increase the system robustness against the motor parameters variation and the sudden variation of the irradiation. The second contribution is to implement the proposed DTC-ISMSC on an FPGA board in order to reduce the sampling period of the system and the delays in the control loop. Moreover, the extract of the maximum power is performed through the Perturb and Observe (P&O) technique. Finally, the performance of the photovoltaic pumping system controlled by the proposed DTC-ISMSC and P&O is demonstrated by digital simulation using Xilinx system generator tool. The ISMSC is compared also with a proportional integral controller. The obtained results have shown the better dynamic performance of the proposed DTC-ISMSC and P&O.","PeriodicalId":266552,"journal":{"name":"2021 12th International Renewable Energy Congress (IREC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130840533","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 three materials (NF, HT and GR) were tested in the dry and steam reforming of methane (DRM, SRM respectively) reactions during 12h stability tests at 700°C. The calcined and the used catalysts were characterized using XRD and DTA/TG analysis. All catalysts were active during the SRM and DRM tests; however, nanofibers showed a slightly higher activity in both reactions.

These RE productions and exchanges occur on a 24/7 basis for dozens of power systems at a time and, thus, constitute a high amount of data. Analyzing this big data and extracting out useful information require computing tools.In this work, we present a calculation model that determines power exchanges paths between areas of an integrated and sustainable power system. This would serve for many applications such as tracking power transactions, detecting grid anomalies or estimating energy costs.The model is based on the mathematical concept of topological sort.

Therefore, the incorporated management system in the integrated module is necessary for balancing, protecting, and optimizing the lifetime of the battery. The proposed SBMS aims to optimize the battery capacity of each PV panel, provides thermal management strategy, and Master Controller Unit (MCU). MCU is the main controller which includes control algorithm for the 3-port microinverter and estimates the state-of-functions such as state-of-charge (SOC) and state-of-health (SOH) to make the integrated system more secure, reliable, and cost effective.

The resonant frequencies for the proposed antenna is within the range of 900 MHz to 5 GHz.
