Transformer is one of the most effective parts of the electrification, but electric vehicle charge equipment generate uncertain, fast and short impulses in the demand side of the grid especially in transformers. Consequently, transformers have been shown unusual reactions which can change standard parameters such as temperature, hot-spot point or same parameters. Therefore, they need to change energy convention at the first step. Afterwards, electrification equipment should be designed by both technical and economic conditions. In this paper, transformers temperature reactions under the electric vehicle fast charge load will be analyzed with literatures. This research aims to determine the best way for cooling or preventing heat tension on the transformers, which sensors cannot sense. Uncertain temperature rise can engage most parts of the transformers such as cooling and magnitude systems.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121650943","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, the poor performance of the MOSFET’s intrinsic diode and the output capacitance present difficulties in voltage source converter bridge-legs. When a MOSFET in this circuit turns on, a charging current has to be sourced into the output capacitance of the complementary freewheeling MOSFET, even if the diode has been deactivated. The peak incoming drain current into the MOSFET turning on can be limited by using a large resistance in series with its gate. However, this increases MOSFET power dissipation. Also, the turn-on propagation delay time is increased. This paper presents a gate driver circuit for profiling the MOSFET’s incoming drain current to provide an improved trade-off between incoming peak current, turn-on power dissipation, and delay time.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121169782","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}

Bidirectional power flows between EVs, buildings and electrical networks were monitored and controlled in real-time. Full control of how, when and the rate at which EVs are charged/discharged with the simultaneous consideration of multiple constraints was achieved by the VIGIL platform.

These studied stills are then compared to those studied in the Middle East and North Africa (MENA), China and India, to determine their suitability in SA. The study further looks at the extent to which SA has implemented solar thermal technologies and their future prospects.

However, some technical aspects remain unsolved and currently slow down its progress, such as the formation of tars in the gas stream. Accurate measurements of a gasifier's operational parameters are central to improve the process' performance and enhance its understanding. It is with this premise that an instrumentation and monitoring system for small scale downdraft gasifier is proposed. The instrumentation system will consist of the measurements of temperature, mass of products inside the gasifier, pressure and air flow, along with actuation of the latter. A chipKIT Max32 microcontroller board serves as the core of the proposed system and act as a link to a computer where the visualization of the process is displayed. A software application was developed in order to concurrently display all the parameters either during operation or using previously acquired data.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133094057","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 study involves looking at the methods and processes used with the purpose of identifying the strengths, weaknesses, opportunities and technologies within SPEN's fault-finding division. The research was achieved by a literature study as well as through numerous site visits to assess real life fault-finding scenarios. The study revealed that there was a lack of a designated LV fault-finding process based on a structured protocol, accordingly a framework was developed to create a methodical approach. This is presented in the form of a flowchart showing different scenarios of faults and their respective finding procedures. The proposed framework aims to streamline the LV fault-finding procedure for practitioners with the ultimate objective of helping utilities ensure a reduction in customer interruptions and customer minutes offline, to improve network reliability.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128536471","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 satellites achieve high fuel efficiency by replacing chemical propulsion systems with electric propulsion (EP) systems. It is possible to increase the payload and prolong the life of the satellite. In the future, it is expected to construct large-scale structures like Space Solar Power Systems which provide the earth with continuous energy in the space. The EP system consists of a Power Processing Unit (PPU) and Hall thrusters. The PPU’s mass is twice that of the hall thrusters. JAXA is studying the anode power supply of the for realizing the light weight PPU. The anode power supply is required to have high efficiency and wide range boost ratio. In this paper, an LLC resonant converter as the control topology of the power supply is evaluated. Two types of converters are designed using #1: 50V or #2: 24 to 32V primary voltage. The converter #1 realized 95% efficiency at 1kW. The converter #2 can output 300V at 93.1% maximum efficiency, and it can operate at about 5.5 pt loss in 8V of the primary voltage fluctuation. In this paper, it is revealed that LLC resonant converter can contribute to realize light weight of the PPU.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116110004","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}
