Traditional DC/DC converters for bucking WES rectifies voltage to the required level but lacks input current continuity as per conventional buck converters’ properties. This results in high tracked electric power ripples which deteriorates tracking efficiency and enlarges turbine mechanical power and torque fluctuations. The latter vastly impacts turbine performance and safety in standalone operation. In this paper, continuous input-output power buck DC/DC converter is employed in a small WES-DC micro grid. It guarantees input/output current continuity and experiences minimal tracked power ripples which are reflected on the turbine mechanical power. Thus, MPPT efficiency is maximized, and turbine protection is maintained. Moreover, this converter features low inductor/capacitor values with less resistive losses thus enhancing reliability and power conversion efficiency and reducing system size and cost. The considered converter is modelled and implemented using simulation work to validate its effectiveness and superiority over traditional buck converters.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127209770","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 southern Florida, future urban areas may be inundated due to sea level rise, and there is conflict between urban expansion and wildlife habitat. In order to direct the urban planning and provide habitat for wildlife, the sea level rise scenario should be projected, and priority protected areas need to be identified. With this aim, we used the digital elevation model data to simulate sea level rise in 3 scenarios (0.4m, 0.6m, and 1.0m) and identified areas that would be inundated. We also applied species habitat data and urban planning data from Florida 2070 into the Zonation software to project conservation priority in the study area. Results showed that in 2070, 3.6%, 4.2%, and 6.5% of the urban built-up area would be inundated respectively, under 0.4m, 0.6m, and 1.0m sea level rise scenarios, and priority protected areas are mainly located in Collier, Hendry, Monroe, and Lee counties. Lands suitable for urban planning are mainly located in the north and middle of the study area.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125731223","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}

Oil that can provide electrical safety is an appropriate oil according to the standards, namely from the electrical side which has a breakdown voltage value of 30 kV at an interval of 2.5 mm. The use of transformer oil in Indonesia still uses Shell Diala B, the oil comes from petroleum where petroleum is not renewable and petroleum waste is classified as a dangerous waste that cause pollution and damage the environment. Plant derived grapeseed oil is a breakthrough and innovation that can be used for transformer oil. The aim of this research is to test the feasibility of grapeseed oil as transformer oil. The finding provides good news, because the results obtained that the breakdown voltage value reaches 71 kV at a temperature of 50 oC - 60 oC, this temperature is the temperature when the transformer operates. With this value in terms of electrical requirements, grapeseed oil is suitable to be used as a substitute for transformer oil that has been used by PLN, namely Shell Diala B which is derived from petroleum.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134320997","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}

To resolve water scarcity, Harvesting Atmospheric Water (HAW) has emerged as a promising alternative water source, particularly for arid areas. However, the efficiency of an atmospheric water harvesting system depends on relative humidity, temperature, water sorption capacity based on the adsorption phenomenon, and other factors. This paper aims to develop a mathematical model to simulate and analyze atmospheric water harvesting using copper chloride. The simulation results show that the proposed mathematical modeling predicts well the water content. The water content reaches saturation at different times, depending on the depth. More work is underway to simulate and analyze atmospheric water harvesting using other types of salts, for example, magnesium sulfate and copper sulfate and compare the results with experimental data, as well as conducting sensitivity analysis to explore how depths, porosities, hydraulic conductivities, temperatures, and relative humidity affect moisture absorption.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114755923","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}

Four MOSFET devices were used for each Hbridge unit. Four independent DC power supplies of different values were connected to the four Hbridge units. Proper gate drive pulses for the 16 MOSFETs of the four Hbridge units to change the switching states were generated on a microcontroller-based Arduino board. Simple microcontroller programming codes was generated to simplify the complex gate control pulses of MOSFETs. It is observed that small number of power switching devices are used to obtain different levels of output voltage. The proposed system was experimentally tested in the laboratory to estimate total harmonic distortion. This experimental study also shows that the THD of the proposed inverter output voltage is decreased when voltage steps at the of the output voltages is increased. The proper switching angles in equal steps has been maintained by using proper drive pulses for power devices to reduce harmonic distortion.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126178458","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}

Therefore, it is essential to focuses the research perspective on government to improve efficiency on green transformation of the energy industry. This study first defines the boundaries of role of government in the transit to a green transformation of energy industry, and then analyses the mechanism of a series of economic policies formulated on the transformation of enterprises in industrial structure upgrading, human capital appreciation as well as the introduction of foreign capital on the basis of technology upgrading from the perspective of the government. The main conclusions are as follows: (1) Government decisions and actions will guide the direction of the green transformation of the energy industry directly or indirectly. (2) Regional heterogeneity has a significant impact on industrial green transformation, government entities need apply valid approach to reduce the unbalanced development of industrial green transformation among different regions. This study has significant theoretical and practical value for governments, considering the regional heterogeneity and different government entities, a coordinated mechanism of law enforcement and supervision is proposed to provide supplements and detailed interpretation to the green transformation policy of the energy industry.","PeriodicalId":151236,"journal":{"name":"2022 6th International Conference on Green Energy and Applications (ICGEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128169265","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}
