The study evaluated the estimation of solar irradiance at different tilt angles by means of different models based on the experimental measurements. For this purpose, two groups of models (isotropic and anisotropic) were carried out: the first group of models was used for estimating the diffuse solar irradiance component, and the second group was used for estimating the global solar irradiance. Five models have been selected and implemented for the estimation of the diffuse solar irradiance component, and five models have been selected for the estimation of global solar irradiance. The results of the analysis were compared with local experimental measurements for diffuse radiation and global irradiance. There are three tilt angles (0°, 30°, 60°) and a two-axis tracking system has been determent for comparison experiments with the model estimated results. The results showed all the selected models generated an error percentage in both the diffuse and global irradiance investigations.","PeriodicalId":36885,"journal":{"name":"Energy Harvesting and Systems","volume":"90 1","pages":"227 - 237"},"PeriodicalIF":0.0,"publicationDate":"2022-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75696830","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}

A 45° inclined long slot steering mechanism is used in this design to collect the vibration energy generated while driving the vehicle, improving the energy use rate and saving the amount of fuel that is consumed. The reciprocating linear motion in driving the vehicle is converted into a rotational movement. Peak efficiency of 50% and the average efficiency of 45% are demonstrated in the MATLAB system.

Extensive use of electric vehicles has already been seen in the automotive industry, especially because of the CO2 emissions and global environmental challenges they help with. A lot of attention has been paid to lithium-ion batteries for their numerous benefits, including lightweight, fast charging, high energy density, extended lifespan, and low self-discharge. This study covers the state of charge (SOC) estimation and management of the lithium-ion battery for sustainable future electric vehicle applications. The importance of adopting a lithium-ion battery management system (BMS) is shown, which guarantees a stable and safe operation and assesses the battery state of charge (SOC). According to the review, the SOC is an important parameter as it denotes the battery’s remaining charge and influences charging and discharging tactics. Additionally, it is shown that existing lithium-ion battery SOC has a positive effect on ensuring the safe and efficient operation of electric vehicles with their charging and discharging capacities. Despite these hurdles, batteries still have certain limitations, such as complex electro-chemical reactions, decreased performance, and inaccuracies in enhancing battery performance and life. This paper thoroughly reviews the approaches used to estimate or capture (SOC) parameters by focusing on the calculation model or algorithm, advantages, disadvantages, and estimation error. It describes a number of aspects and obstacles that have been identified and suggestions for their use in the development of BMS and for estimating SOC in future EV applications are offered. The rising attempts to improve the high-tech future EV applications, SOC calculation method, and energy management system will be enhanced by this review’s highlight insights.","PeriodicalId":36885,"journal":{"name":"Energy Harvesting and Systems","volume":"43 1","pages":"211 - 225"},"PeriodicalIF":0.0,"publicationDate":"2022-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82606680","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 thickness (A), porosity (B), SiO2 (C), and Al2O3 (D) contents of ceramics are statistically significant (P-value<0.05) for both responses of the maximum power density (MPD) and the coulombic efficiency (CE). The interactions of AB and AC have significant influences on the MPD. For highly porous ceramics, including the unglazed wall ceramic (MFC-UGWC, 30.45% porosity) and Yellow ceramic (MFC-Y, 28.9% porosity), the MPD and CE are boosted by raising the thickness of membranes. The MPD and CE values have been enhanced from 225.07 to 321.11 mW/m2 and from 51 to 68%, respectively, by thickening the UGWC from 3 to 9 mm. Similarly, the power performance and CE of the MFC-Y have been grown by 32% and 148.6%, respectively. However, both the MPD and CE responses have been reduced from 106.89 to 57.65 mW/m2 and from 29 to 18.3% for the denser unglazed floor ceramic (UGFC, 11% porosity) as a consequence of thickness increment from 3 to 6 mm. Furthermore, the chemical composition of ceramics has a crucial impact on the overall performance.

In circuits including inductors and capacitors, if the value of zc = zl becomes, an intensification or resonance state is created in the circuit. In circuits and networks that have saturated inductors, nonlinear resonance or ferro resonance is created, Ferro resonance is a nonlinear resonance phenomenon that occurs between the network capacitor and the nonlinear inductance of the transformer during saturation. Ferro resonance at the main frequency and higher frequencies cause insulation problems and at low frequencies causes thermal problems. In the event of this phenomenon, the voltage range increases to a considerable extent and may also be distorted, which due to the structure of the winding connections in transformers can cause damage to electrical installations. Methods: In this paper, we study and simulate the phenomenon of ferro resonance and provide solutions such as using high resistance on the primary side of the transformer and the combination of resistors and inductors on the secondary side of the transformer to damp the ferro resonance in MATLAB software. Furthermore, the utilization of surge arresters is discussed in detail. Results: It is illuminated that utilization of suggested approaches has an acceptable reduction rate on the damping of ferro resonance fluctuations. Especially when using resistor and inductor simultaneously the fluctuations reduce and ferro resonance is damped immediately. Conclusion: It is important to pay attention to the transformer and the amount of capacitors in transmission lines, especially cable lines. Furthermore, asymmetric switching is another important factor. High resistance can reduce fluctuations but causes power losses in the circuit but using Resistance and inductor structure are able to create acceptable damping and reduce fluctuations without loss problems. The presence of a surge arrester can also reduce the overvoltage caused by ferro resonance to an appropriate level.","PeriodicalId":36885,"journal":{"name":"Energy Harvesting and Systems","volume":"88 1","pages":"203 - 210"},"PeriodicalIF":0.0,"publicationDate":"2022-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88168536","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 fact, the combination of wind, water and solar energy can replace depleting fossil fuels which produce greenhouse gases on the one hand, and on the other hand cover the entire energy needs of the planet. Solar energy is both clean and non-polluting, moreover it is one of the most popular solutions for households as an alternative to fossil fuels. Therefore, the use of photovoltaic systems reduces the energy supplied by the public grid and inevitably decreases the amount of the energy invoice in the long term. Due to the increase in the number of bachelor students in recent years, the Ibn Tofail University in Kenitra, Morocco, has been required to build new buildings and laboratories to ensure a good study environment for its students. This has led to an enormous increase in the electricity bill. In this context, our project aims to decrease the energy bill of the two institutions: National School of Applied Sciences (ENSA) as well as National School of Commerce and Management (ENCG), by studying the technical and economic aspects of photovoltaic installations for self-consumption purposes, as well as the installation of solar streetlamps to improve the performance of nocturnal lighting. In addition, an initiation to the intelligent smart building concept that allows the centralized technical management of the installed equipment, and more precisely the DALI lighting protocol, was extended. Indeed, this system will allow us to control the consumption of the loads remotely and in real time for a better comfort and without neglecting the reduction of the energy bill.","PeriodicalId":36885,"journal":{"name":"Energy Harvesting and Systems","volume":"46 1","pages":"165 - 177"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84710164","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 recent years, the concept of transforming waste into a productive source of energy has gained attention. Several forms of agricultural products, chemical reactant, and treated blends have been studied by scientists all over the world over the past few decades. The work’s goal is to determine the effectiveness with using treated transformer oil (TTO) as diesel engine fuel, thus minimizing the environmental issues created by its discharge into open space. This study also aims to capitalise used transformer oil as a renewable fuel source into compression ignition engine, since using waste oils decreases the cost of fuel. The characterization (aniline point, calorific value, density, diesel index, flash point, kinematic viscosity) of treated transformer oil (TTO) was determined and blended with diesel in the proportion of 10% (TTO10), 20% (TTO20), 25% (TTO25), 30% (TTO30), and 40% (TTO40) treated transformer oil. The outcomes are evaluated in comparison to the same diesel engine’s operation. According to the findings of the study, blends of treated transformer oil and diesel fuel may be a best choice for diesel engines since they have the same calorific value as diesel fuel. The brake thermal efficiency of blends containing up to 20% TTO is greater compared to diesel fuel. It lowers as a proportion of treated transformer oil increases and increases as the load increases. Furthermore, when the fraction of TTO in blends grows, brake specific fuel economy (BSFC) declines with load.","PeriodicalId":36885,"journal":{"name":"Energy Harvesting and Systems","volume":"19 1","pages":"75 - 81"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83367555","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}
