The ASMRO proposed in this paper can provide accurate resistance value of SRMs, and reduce the problem of poor system control accuracy caused by the change of resistance value. The proposed method has simple logic, good real-time performance, and high recognition accuracy, which is important for improving the applicability and speed regulation performance of SRMs.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130015202","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 traditional cylindrical lithium-ion battery has temperature unevenness problem, especially when operating at high rate. The difference between measurable surface temperature and maximum temperature of the battery may be large. A hollow structure design of the cylindrical lithium-ion battery is proposed. The hollow cylinder structure has the advantages of better cooling performance and the convenience of putting temperature sensors inside of the battery. The battery model coupled with electrochemical model and thermal model is established. Thermal states of the hollow battery and the solid battery under air cooling condition are simulated for comparison. Results show that the maximum temperature of charging hollow battery is lower and the temperature unevenness problem is also improved. At higher charge rate, the advantages of the hollow cylinder structure become more significant. When the inner diameter increases, the total volume of the hollow battery becomes larger quickly, leading to lower volume energy density. The conflict between this drawback and advantages of lower maximum temperature and better temperature unevenness is analyzed.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127948202","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, limited to the manufacturer’s confidentiality agreement, the internal structural parameters of the grid-connected inverter cannot be known in the engineering field so that the grid-connected inverter appears a Black-Box. For this case, this paper presents a Black-Box method, using impedance measurement method to obtain the equivalent impedance model of grid-connected inverters, and then the impedance model of the whole system is obtained. On this basis, the positioning of the primary device for the induction of harmonic resonances was done by performing participation analysis of the system.

DR models are generally divided into price-based DR models and incentive-based DR models. However, a single type of DR models might bring new imbalance between supply and demand in view of the strong subjectivity in DR participation behavior. To comprehensively consider the influence of various factors on DR behavior and regulate the behavior of DR participants, this paper proposes a hybrid DR model under a distributed reputation framework. In this model, the power consumption of a participating power user is subject to dynamic pricing, and rewards and penalties are given according to the actual response capacity. Reputation scores of users and aggregators play an important role in the prioritization of invitation confirmation, task allocation, and discount calculation. This model is shown to be helpful in increasing the benefits of participants with good reputation by simulation.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115955852","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}

Based on game theory and NSGA-II algorithm, a two stage generation-grid-load-energy storage interactive optimization operation strategy to promote distributed PV consumption was proposed. Firstly, Dynamic loadability of distribution network (DLDN) is defined to endow demand response resources in distribution network with time and space characteristics. It provides a “bridge” for the distribution system to promote the two stage optimization of distributed PV local consumption power scheduling and active/reactive power coordination control, and gives the solution method of DLDN. Secondly, a two stage interactive optimization operation framework of generation-grid-load-energy storage is proposed. In the first stage, an electricity trading strategy is formulated based on game theory, which can promote the local consumption of distributed PV and balance the income of supply and demand. In the second stage, the power trading strategy of the first stage is tracked through the active/reactive power coordination control of the distribution system to optimize the operation state of the distribution network. Finally, an example is given to verify the effectiveness of the proposed method.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134016577","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}
