It can be noted that none a single sustainable energy technology will be able to achieve the carbon reduction independently. The simultaneously developed of many sustainable energies still needed. The recent growth in sustainable energy, especially tidal and wave energy is shown that the nano-scale generators for the river and ocean are still required. This is due to the most country in the world have the river and the ocean covers approximately 70 % of the surface of the earth. In practice, the tidal energy is the interaction between the gravity of the sun, earth, and moon, and hence it results the rise and fall of the tides. Whereas, the wave energy is the water movement due to the frictional drag of wind over the water surface. Despite these advantages, tidal and wave energy continued to face challenges in achieving a high efficiency output to generate the electricity, Moreover, some standards and regulations of grid connected are needed to revise in order to ensure its operations and safety. These allow small-scale distributed generator such sustainable energy resources to cooperate with the exiting power network. Therefore, the paper reviews and proposes the nano-scale generator of tidal and wave energy for river and ocean. The proposed generator can support at the riverbank, in the middle of river, bays, shoreline, coastal estuaries, and in the middle of ocean. The generator should be easy to install and maintenance, while the chosen material structure of generator has the corrosion resistance of the saline water. The generator must follow the standards and regulations in order to ensure its safety.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"406 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133945721","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 emergency case, both brake distance and braking time of HST will be longer than normal situation, therefore, safety for passengers and management about controlling the driving of HST are very important. The aerodynamic brake effected on the dynamic motion of trains during braking are analyzed and considered as the aircraft’s flaps that is applied in HST. The area of aerodynamic brake functions as the additional drag force during braking. The HST with the speed from 200 km/h to 350 km/h is a case study of this article. As the results, it is found that the braking time and brake distance can be reduced in comparison with the system without aerodynamic brake. The braking distance is reduced by 394 m or 0.13% when the area of aerodynamic brake increases to 100%. However, when aerodynamic brake is used in real situation, it should be chosen the area of aerodynamic brake that is suitable to the dimension of train body, and it should not block electricity cable, energy resource in the train, tunnel and so on. Moreover, it can reduce the energy of braking, and energy saving is reduced by 3.23 kWh or 0.692%, therefore, the mechanical brake and its maintenance have efficient advantages by extending its service life.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133521413","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}

These robotic applications are required an ability to aware their operating conditions due to safety reasons as they are likely to be operated close to humans. One of the major parameters to examine the situations is rotor torque which conventionally acquired by a torque transducer. However, using such device requires extra cost, bulky mechanical installation, and data acquisition electronics. Due to this trade-off, we propose a machine learning based method for rotor torque estimation. The information used in the estimation process are solely electrical signals generated by the motor itself without any actual sensor required. In this paper we present an investigation and feasibility study of the proposed sensorless torque estimation. A motor test bench has been developed for observing motor characteristics also for collecting information to create torque prediction models. Numerous statistical based machine learning methods have been applied in this work including Neural Networks regression, Linear regression, and Stepwise regression. The proposed system has been used to created prediction models according to the occupied regression methods. The estimation performance has been considered by comparing the estimated results with ground truths from an actual torque sensor. The estimation model based on Neural network regression has achieved highest accuracy at 0.11 of RMSE and 0.996 of R value. The results shown the potential of applying the proposed senseless torque estimation for robot application with acceptable performance.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129335860","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}

This article is the analysis and trial plan to create an energy storage systems model with the vertical concrete stacks to form a suitable configuration. The gravitational energy storage system is an energy transformation between the gravitational potential energy and the kinetic energy of the concrete stacks moving down to the electrical energy via a generator. A comparative efficiency study of the charging and discharging energy system during lifting and dropping concrete stacks are also presented. The case study is based on the feasible square prism concrete stacks in vertical shape with a weight of 100 tonnes per stack. The height of the system is about 50 m. As the result, the power system obtains the energy from the gravitational energy storage as a discharging mode by 9.68 kWh, however, supplies the energy to the gravitational energy storage as a charging mode about 12.10 kWh with the overall efficiency of 80%. The finding in this study, the discharging mode of the gravitational energy storage is suitable to use in the power system to support the high demand during the on-peak time or the duration of the high cost of electricity whereas the charging mode is possibly used in the duration of off-peak time with low cost of electricity or supported by the renewable energy sources around.","PeriodicalId":342582,"journal":{"name":"2020 International Conference on Power, Energy and Innovations (ICPEI)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133196145","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}
