One way to achieve this goal is to use waste heat recovery systems. Latent heat energy storage using PCM is one of the promising solutions that gained the attention of researchers due to its worthwhile characteristics, including a high storage density, and the capability to restore energy at a constant temperature. However, PCMs, especially organic PCM, still suffer from a low thermal conductivity that reduces their thermal performance. The aim of this study is two folds. First, it provides a good understanding of heat transfer during the charging cycle (melting of the PCM). Then investigates the role of adding fins in enhancing the energetic performance of the regenerator. For this reason, a horizontal heat exchanger filled with PCM (Paraffin wax with melting temperature of 325 K) is numerically investigated using the commercial software Ansys Fluent. The numerical results demonstrate that the longitudinally finned case provides better thermal performance compared to the finless case. Thus, the addition of fins allows a reduction in the melting time by 46.3%.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127159374","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 physicochemical analyses of a biomass before valorization are an essential step to understand its behavior during the energy conversion process. In this context, a series of physicochemical and thermal analyses were performed on olive pomace samples, in order to evaluate the properties of this biomass and to valorize it as a fuel. The ultimate analysis prove that olive pomace constitutes of an important amount of Carbon, Oxygen and Hydrogen (48.2%, 44.3%, and 6.1% respectively) while Nitrogen and Sulphur with small quantities (1.4% and 0% successively). Furthermore, OP samples present a high heating value of 22.5 MJ/kg. Based on thermal analysis, we determine the characteristic combustion parameters. The ignition temperature of samples is about 243 °C while the burnout temperature is 480 °C. in addition, the ignition index D of the studied materiel is 12.8. 10-3 whereas the combustion index S is about 5.95. 10-4. The obtained results prove that olive pomace is a good candidate for exploitation as fuel and can replace fossil fuels.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130576594","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}

Nonetheless, they still face many challenges, such as the influence of the State of Charge(SOC), ambient temperature and current rates on their life cycle. Which makes battery states prediction and thermal management essential to improve the Li-ion battery performance. Combining a three-state equivalent circuit model and a two-state thermal model, this paper proposes a coupled electro-thermal battery model capturing the battery state of charge, surface and core temperatures. Knowing these three key factors ensures better control of the battery operation conditions to prevent excessive heat generation. The model is expressed in a state-space form to allow battery state estimation, SOC and thermal prediction. A simple state observer and a robust nonlinear state estimator for SOC prediction are presented and compared. Then a nonlinear observer for core and surface temperature is modeled, and the obtained results are discussed.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125366847","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}

In order to contribute in the system frequency stability, the WECS have to inject an additional active power support into the power system. To do that, an additional frequency regulation control methods have been adopted to change the reference value of the electromagnetic power of the DFIG. These control strategies are the synthetic inertia control and the droop control. Furthermore, an additional technic called automatic generation control (AGC) has been used for adjusting the power output of multiple generators in the microgrid in response to changes in the load. The role of the AGC is to restore frequency to its nominal value by using a supplementary integral controller. Moreover, the control of the wind turbine generator is necessary so that it can provide the requested power. We used the Active Disturbance Rejection Control (ADRC) method and in order to assess its performance, the ADRC strategy was compared to the classic PI controller. Modeling and simulation are carried out in MATLAB/Simulink environment.","PeriodicalId":361856,"journal":{"name":"2021 9th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126228092","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}
