High voltage direct current (HVDC) arc events in cables can lead to fires within EVs. Therefore, in this paper we investigate the failure modes mechanisms and effect analysis (FMMEA) of this safety critical issue. The onset of these failure modes can be multi-factorial so we created a statistical design of experiment to investigate the evolution and mitigation of these failures. Analysis of the arc characteristics collected in laboratory models has been decoupled and classified into time sub-domains. Utilising continuous wavelet transform (CWT) for capturing frequency features and minimizing the influence or erroneous signals. Verification testing was performed using a reference arc model in Simulink for comparative analysis of the experimental and simulated data. Mitigation of arcs via the incorporation of a fuse has been proven to provide sufficient circuit protection. Our results indicate that our methodology provides an accurate framework for cable arc classification and mitigation.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"62 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123306049","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}

Through the switching of transferrable load and heat storage device, a large number of loads are transferred to the period when wind power resources are abundant and conventional loads are relatively low, so as to absorb the forced wind abandonment, thus improving the utilization rate of wind power resources through transferrable load and heat storage device. Based on the further study of how to improve wind power absorption, this paper discussed the influence of wind power absorption system based on transferable load and heat storage devices to the traditional scheduling schemes. The objective function is established with the minimum forced wind abandonment volume and the minimum cost of the comprehensive operating system. The multi-objective genetic algorithm is used to solve the problem, and the optimal solution set can be obtained. Then the single objective optimization function is established by weighting method, and the optimal compromise solution and the final scheduling scheme is finally obtained. This paper takes a power grid operation system as simulation example, and shows that the dispatching scheme of using transferrable load and heat storage devices can greatly reduce the operating cost of the system and enhance the wind power absorption capacity of the system, compared with the traditional dispatching scheme.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124812908","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}

Workload modeling is the basis of computing resource configuration for edge computing terminals. Thus, this paper proposes a workload modeling method of edge computing terminals for distribution service. According to the timing logic of distribution service, the service is decomposed into several tasks and the sequential logic diagram is constructed. In the sequential logic diagram, directed edges are used to represent the dependency of the tasks. Combining the internal architecture of the edge computing terminals with the sequential logic diagram, the mathematical workload model is formulated. Based on the formulated models, a workload curve generation algorithm is proposed to obtain the computing resource demand of distribution service. Finally, the computing resources of the edge computing terminal are configured according to workload curve. Simulation results verify the effectiveness of the proposed model and method.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124236668","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 has shifted much focus towards the solar energy which is green and renewable. In order to solve the shortcomings of low utilization, low automation and high cost of the traditional photovoltaic system, we propose an automatic tracking and maximum power output device for silicon photocell. The system is composed of solar automatic tracking device, maximum power point tracking (MPPT) system (controlled by STM32) and monitoring system based on Zigbee wireless. The solar automatic tracking device adopts four-quadrant photoelectric detection mode, realizes omni-directional and high-precision biaxial automatic tracking through logic circuit judgment, and makes maximum use of solar energy. The four-switch Buck-Boost circuit is used as the main circuit to realize wide range adjustment and synchronous rectifier control, which is combined with soft-switching technology to greatly improve the conversion efficiency of the system. ZigBee network monitoring system takes CC2530 as the node of transceiver. Results of testing showed, that solar automatic tracking device can track the solar trajectory with high precision and realize the maximum utilization rate of light intensity. The tracking accuracy of MPPT controller reached 99%, and the conversion efficiency also improved greatly, up to 98%. The monitoring system based on Zigbee wireless worked stably. In summary, the device effectively improves the utilization rate of solar energy.
