This paper introduces three kinds of AT power supply modes, and combined with the current situation of the harmonic problems in traction network caused by the mixed running of AC-DC electric locomotive and AC-DC-AC EMU, carries out the simulation comparative study on the harmonic characteristics of traction network of multi-vehicle mixed running lines under three kinds of AT power supply modes. Taking SS6B locomotive and CRH2 EMU, which are widely used in the actual situation at present, for examples, the interactive simulation model between the vehicle and traction network is established by using Matlab/Simulink simulation software. Through the simulation analysis of the harmonic characteristics of SS6B electric locomotive and CRH2 EMU, the correctness of the comparison conclusion in this paper is verified. On the basis of the vehicle network interactive simulation model, the harmonic characteristics of the traction network under different traction network lengths, different locomotive positions and different locomotive working conditions of three AT power supply modes were compared and analyzed. The study results show that the vehicle network interactive simulation model established by the three AT power supply modes can accurately reflect the influence of AC-DC locomotive mixed running on the harmonic characteristics of traction network.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122013056","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":null,"pages":null},"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}

Firstly, the reliability models of generating units and gas wells are proposed considering the failure characteristics. On this basis, the reliability constraints of IGPSs are developed considering the impacts of gas contingency on EPS operation. Furthermore, the economy-reliability-coordinated planning model is proposed to determine the deployment of gas storage and power units. The developed model is to minimize the total cost including investment cost, operating cost and load curtailment cost considering the operating constraints and reliability constraints of IGPSs.

New methods are required for operation benefits evaluation under the future low-carbon energy framework. In this paper, a feasible and comprehensive evaluation index system of operation benefits is proposed. Firstly, an index-based evaluation criterion is established to evaluate the operation benefits on reliability level, intelligence level, power marketization level, economic benefits, environmental benefits, and social benefits. Next, a mathematical evaluation method is proposed based on the indexes. The analytic hierarchy process (AHP) and the anti-entropy weight method (AEWM) are used to calculate the combination weights of indexes. The proposed evaluation index system can be used to evaluate the operation benefits of power grid under the future low-carbon energy framework. Furthermore, it can also be utilized to compare the pros and cons of different grid operation planning schemes in China.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134225664","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}
