In the present study, the combustion characteristics and performance of heavy oil are investigated. Further research on heavy oil is developed by adding content of Liquefaction Bio-Oil, because of its complex nature. So as to better understanding of HFBO combustion process and to improve efficiency and control emissions. The techniques used to study the heavy oil is TGA-FTIR, Single droplet, Gas analyzer and Spray combustor. All the required techniques are used to investigate heavy fuel blended oil (Mixture of heavy oil and Liquefaction Bio-Oil) combustion behavior with various HBFO of 3%, 5%, 7% and 10%. The combustion behavior of heavy fuel blended oil was performed using the thermo-gravimetric analysis (TGA) at temperature 30 °C to 800 °C at various heating rates of 5°C/min and 10°C/min in air atmosphere. TG and DTG were used to study the mass loss characteristics due to the thermal degradation of HFBO. Single droplet and spray combustion experiments of heavy fuel oil with Liquefaction Bio-Oil are used to investigate the evaporation, atomization, combustion behavior and improve efficiency. The results show that improve in the combustion performance and characteristics of heavy fuel blended oil by using TGA. The droplet test results are good agreement with HFO and heavy fuel blended oil (HFBO) in two cases, found that ignition temperature, burnout temperature and combustion index are more satisfactory.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122425966","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}

However, due to the variability and uncertainty of these sources, stable operation of the power system with large solar and wind power penetration is a big challenge for system operators. In order to enhance the contribution efficiency of solar and wind power in the power market, a strong ancillary service system is essential and must be reasonable priced. The ancillary services considered in this paper are spinning reserve, non-spinning reserve. In addition, a model for calculating and comparing generation costs for energy and ancillary services, with and without penetration of solar and wind power in the power market have been proposed. Consequently, this model has been developed and validated with a case study. The results show that in a power system with large proportion integration of solar and wind power, the energy and ancillary services generation costs for the power system are high. Besides, the feed-in tariffs of solar and wind power are more expensive than the traditional electricity generation, which leads to high locational marginal prices of the electricity market.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115618576","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 is simple to use with clear link-up with contemporary national standards, but it is limited to the verification of Ultimate Limit State. Above that, the author’s experience is that even professionals have inadequate knowledge of the main principles for the creation of the models in cases of atypical details. Simplified assumptions of Stress Field Method are similar to the ones used in hand calculations, but the method is improved to allow ductility and Serviceability Limit State verifications. Stress Field Method can be seen as a generalized Strut-and-Tie Method, in which 2D members with stresses instead of force resultants are considered. The method is based on clear material properties and strength criteria corresponding with the ones used in national codes and regulations. Despite the obvious benefits, the method is not as widely used in common practice as Strut-and-Tie Method. To demonstrate the potential of Stress Field Method, the assessment of well-known example of deep beam with a large opening was performed using both methods in Eurocode context. The results of both analyses were compared. The influence of (i) detailing and (ii) model parameters was investigated with respect to ultimate load and mode of failure. The study has shown (i) wider possibilities to proof structural safety and reliability than the Strut-and-Tie Method would allow, and (ii) an excellent agreement of the results in the checks viable by both methods.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114719797","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}

Our device includes two modules. The power interface with the appliance is based on the voltage and current sensors connected to the Arduino Uno. The processing module uses the machine learning approaches such as neural network or K Nearest Neighborhood (KNN) to recognize the electrical appliances plugged into in real time. All of the recognized in-home appliances datasets then can be uploaded to the home energy management system for further applications. For instance, the system gives a warning message to the user when the appliance has an unusual power factor or an outlier in power consumption. This warning is sent via email or mobile phone. Compare to other commercial smart plug devices, our device has more functionalities at a low price.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116753744","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 setup of experiment and parameters design of the bionic wind turbine blade was then progressed by Taguchi method and the ANSYS Fluent simulation software was used to perform the numerical computations of the aerodynamic and flow characteristics of the wing of maple’s seed. Also, based on the experiment and simulation results, the Minitab17 software was used to analyze the data. The simulation results, by an inspection of the trend of the lift coefficient curves, indicated that the seed wing of the green maple has a larger range of angle of attack, $0 ^{mathbf {0}}$ to $50^{mathbf {0}}$, without a stall. The results for the optimal design parameters show a good agreement with the achievement for the best combination of the parameters are: A3 (the number of blade = 3), B3 (the swept area = ${0.24,,mathrm{m}} ^{mathbf {2}}$), C2 (the angle attack = $15^{mathbf {0}}$) and D2 (the steady headwind = 5 m/s., which shows an aerodynamic advantage. In addition, the wind tunnel experiments of the wind turbine, with 3 bionic blades, $0.24,,mathrm{m}^{mathbf {2}}$ swept area, $15^{mathbf {0}}$ angles of attack, and 5 m/s steady headwind conditions showed that the highest wind/electricity power transform efficiency can be reached up to 37%.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121081367","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}
