EVs have a dual role when accessing the micro-grid: they can be regarded as loads when they are charging. Simultaneously, when electric automobile battery has sufficient power, it can input power to the micro-grid load. Firstly, this paper introduces the operating principle of the converter for charging and discharging of EVs. The converter is a critical component of the convergence and transmission of electrical energy in DC micro-grid, electric automobile and energy storage system. Secondly, the overall control strategy of chargedischarge system of electric automobile is put forward. Finally, the simulation outcomes show the practicability and availability of the charge-discharge control strategy.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117343389","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}

It is imperative to address this issue either by expanding and reinvesting the network or regulating the charging load in a smart way. This paper proposed a novel hybrid hierarchical strategy for electric vehicle (EV) charging. By synthesizing the strength of the two mainstream control strategies-centralized and decentralized control strategy, it divides the charging process into two levels with different optimal objectives. Considering the stochastic of the charging behavior, it deploys MATSim to simulate the driving patterns and aggregate the EV with similar driving patterns into a so-called Virtual Battery Aggregation (VBA) Model. To verify the effectiveness of the proposed method, an 18-bus system is simulated and 4 different control methods are compared and analyzed regarding to peak hour node voltage, line load, and daily load curve.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115508471","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}

How to quickly and accurately detect network traffic anomalies and reduce the labor cost of detection model training has become an important issue in the development of network technology. Aiming at this problem, this paper proposes a Bayesian-based industrial Internet service abnormal detection algorithm. Based on the abnormal detection of LightGBM traffic, Bayesian optimization can further improve the efficiency and accuracy of the algorithm's traffic anomaly detection and reduce the manual participation of model training.

As there is no independent electricity price for battery energy storage in China, relevant policies also prohibit the investment into the cost of transmission and distribution, making it difficult to realize the expected income, which to some extent restricts the development of battery energy storage power station and new energy storage technology. This study analyzes the location benefit, system benefit and their combination of grid side battery energy storage, and compares them with the cost of the whole life cycle of battery. It evaluates the cost-effectiveness by using the indexes of income flow, net present value, dynamic investment payback period and intrinsic rate of return. The results show that under the existing market and policy conditions, the single price can not recover the investment cost. In order to promote the development of battery energy storage, the subsidy and price mechanism should be improved, and the participation of energy storage in the spot market should be actively promoted.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128886675","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}

Elastic composite cylindrical roller bearing (hereinafter referred to as elastic bearing) is a new type of bearing which can improve stress concentration and comprehensive performance. By means of theoretical analysis, the complex load distribution of emu's axle box is determined, the new bearing and ordinary bearing are analyzed by means of numerical analysis, and the stiffness and maximum equivalent stress of the two bearings are calculated by taking the pre-load and the number of rollers as variables. The results show that the stiffness and maximum equivalent stress of new bearing and ordinary bearing increase with the increase of preload. As the number of rolling bodies increases, the stiffness increases but the maximum equivalent stress decreases. Considering the comprehensive fatigue failure, the elastic bearing has obvious advantages in static stiffness compared with ordinary cylindrical roller bearing.","PeriodicalId":250211,"journal":{"name":"Proceedings of the 2nd International Conference on Information Technologies and Electrical Engineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114365392","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}
