This paper aims at a power system model based on the framework of \"distribution network - industrial park micro grid - enterprise load user\", and studies a power control method of micro grid tie line based on user reward scheme. Firstly, the objective economic function of the micro-grid in the park is established, and then the optimal reward scheme for internal load users of the micro-grid in the park is derived according to two typical load response models. The power fluctuation can be stabilized by encouraging load users to respond to demand, thus the internal load users can benefit while reducing their own economic losses and the day-ahead scheduling results of tie lines can be effectively tracked. Taking a production industrial park as an example, the effectiveness of the proposed optimization model and algorithm is verified by an example analysis.","PeriodicalId":101544,"journal":{"name":"2020 Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131009454","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}

And the average load far less than 50% result in relatively low oil temperature, the very uneven rise of temperature lead to the very uneven distribution of insulation aging. In order to evaluate the aging life of oil-paper insulation of traction transformer under shock load effectively, in this paper, Ekenstam aging kinetic model was optimized considering the effect of shock temperature, shock duration and shock interval on cellulose degradation rate of insulating paper. Firstly, the effects of shock temperature, shock duration and shock interval on the parameters of Ekenstam model are analyzed and determined by handing and testing experimental materials. Then, according to the test data, the Ekenstam optimization model considering shock temperature, shock duration and shock interval is obtained. Finally, the optimized model is verified by experiments. The results show that the optimization model can effectively evaluate the aging life of oil-paper insulation of traction transformer under shock load in the temperature range, which provides a basis and reference for the subsequent related research.","PeriodicalId":101544,"journal":{"name":"2020 Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114508285","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 this paper, taking the independence of hardware and the openness of software platform into account, we design a universal secondary device platform for the typical application requirements in power transformation and distribution. The platform adopts several key technologies including double-layer driver, container, interface standardization design, micro application development framework, etc., solving the generic open problems of software platform under the constraints of hardware types and functional reliability of secondary devices in different application scenarios. Finally, we reach the goal of definition of software for secondary device.

However, the HPPC was originally designed for determining the dynamic power capability of the tested battery using a profile that incorporates both discharge and regen pulses, which is quite different from the parameters’ identification, therefore it is meaningful to make the profile fit the parameters’ identification. Aiming at this, this paper investigates the impact of the different HPPC profile on the identification accuracy from two aspects: the pulse width of the simulating current and the rest time. Firstly, the process of the HPPC test as well as parameters’ identification is given. Then, identification results of the HPPC profile with different pulse width and rest time are compared both by simulation and experiments. The results show that both the pulse width and rest time have a significant impact on the accuracy of the parameters’ identification. If the pulse width and rest time are both small, increasing either of them can improve the identification accuracy significantly, while if the pulse width or the rest time is large enough, the identification accuracy can’t be further improved evidently by prolonging any of them.","PeriodicalId":101544,"journal":{"name":"2020 Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"15 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129637061","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}

A regional integrated energy system optimal operation model considering flexible heating load is proposed. Firstly, combined with the basic principles and operation characteristics of typical equipment in the integrated energy system, the main equipment model of the integrated energy system is formed. Based on the user's work and rest rules, a flexible heating load model considering the user's flexible comfort constraints is constructed to increase the system's operation flexibility. Then, a mathematical model for the optimal operation of the regional integrated energy system based on the bus-based structure is constructed. Finally, three different heat and power dispatch methods are defined to analyze the benefits of the combined heat and power dispatch in an integrated energy system. The simulation results show that the optimal operation model of regional integrated energy system considering flexible heating load can improve energy efficiency and reduce the system operation cost.","PeriodicalId":101544,"journal":{"name":"2020 Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130199706","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}
