In order to solve the problem of difficult demand response capacity assessment, this paper proposes a method of regional residential response capacity assessment based on non-intrusive load decomposition. Firstly, a non-invasive load decomposition model based on XGBoost algorithm is established, and then the interruptible load of users is decomposed by this targeted model. Then, based on the electricity consumption of interruptible load, the response ability of users at each moment is calculated. Finally, the users are aggregated to get the responsiveness of the residents of the area. The results of the validation on the data set show that this method has high accuracy in demand responsiveness assessment.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123023727","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 transient disturbance tests were carried out on the simulation system including the package control model provided by manufacturers, and the key influencing factors of the transient characteristics were obtained. Secondly, the Z-U index, which is only related to the topology of the farm field, was proposed for wind generating sets clustering and wind farm equivalent system reconstruction.

Firstly, the small-disturbance linearized model of the sending end system is established, in which the internal second-order harmonic dynamics of MMC and the dynamics of wind generator grid-side phase locked loop (PLL) is considered. Then, the effects of wind farm active power, AC voltage control parameters of MMC and PLL control parameters on the stability of the sending end system are analyzed by root locus. Finally, a full-scale electromagnetic transient simulation model of MMC based wind farm integration system is established in PSCAD/EMTDC.

However, the parasitic parameters of planar transformer make the optimal operating point of the converter offset and reduce the efficiency. In this paper, a SiC MOSFETs based LLC resonant converter with an optimized planar transformer is modeled, analyzed and verified by experiments. The leakage inductance of the proposed winding structure is only 50% of the fully interleaved structure. The proposed converter is more ideal with more accurate resonant frequency and gain. The measured resonant frequency is 99.67 kHz, which is only 0.33% lower than the design value of 100 kHz. With the lower loss, the more ideal transformer increases the efficiency of LLC converter by 3%. Furthermore, the gain of the LLC converter at resonant frequency is higher and the gain-frequency and gain-load curves are more ideal.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131043022","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, when the length of the cable is extremely long, the stray capacitance between the core wire and the shielding and between the core wire and the core wire cannot be ignored. Large stray capacitance will have a great impact on the control circuit and threaten the safe and stable operation of the system. In order to reduce the stray capacitance between the cable core wires, an optimal configuration of the cable core wire position based on marine predators algorithm (MPA) is proposed. By reasonably optimizing the position of each core wire in the cable, the stray capacitance between the core wires is minimized. At the end of this paper, by setting the cross-sectional area of the cable to 200 mm2, a single cable core radius of 1.5 mm, the effectiveness and superiority of the proposed method are verified by optimizing the configuration of the three-core and five-core cable models, and the cables with more cores can be optimized to achieve the minimum stray capacitance.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114287825","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}

As the most direct cause of deformation and rupture of transformer oil tanks, the pressure distribution changes caused by the internal arc fault in oil-immersed power transformers is worth to be studied, but the current research is not yet complete. And protection schemes based on pressure characteristics also mostly remain in the stage of pressure relief devices that act on pressure amplitude reaching threshold. In this paper, a real scale 25MVA/110kV oil-immersed power transformer is reformed, several groups of arc breakdown experiments in transformer oil are carried out. And multipoint pressure signals on the oil tank wall under the internal arc fault are simultaneously recorded and analyzed. The experiment results and analysis show that the amplitude of pressure signal is negatively correlated with the distance between the fault point and the pressure measurement point, and the time delay of pressure signal is positively correlated with the distance between the fault point and the pressure measurement point. The pressure signal measured at the pressure measurement points that are relatively close to the fault point have an obvious dominant frequency. The research results lay a foundation for the further development of new non-electric protection based on the pressure characteristics.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114756798","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 recent years, many countries, including China, have proposed various renewable energy policies, such as establishing the carbon emission trading market and developing the renewable energy quota system. Besides, demand response programs have been raised to alleviate the carbon pressure on the system and increase renewable energy consumption. However, limited effort has been expanded in quantitatively analyzing the impact of various renewable energy policy factors on the consumption level of renewable energy resources. Furthermore, the volatility and stochasticity associated with the high penetration of renewable energy sources pose a great challenge to the operation and dispatch of power systems. To solve these problems, this paper proposes a stochastic unit commitment model considering the carbon emissions trading/ carbon emission permits (CET/CEP) policies, the renewable energy quota system, and the demand response.
