Contrast to the electric mechanical based traditional power source, the short-circuit current out of ES (energy storage) inverter is quite different during fault period. The steady-fault model is always used for analysis but lack of sufficient accuracy. The control strategy of ES inverter considering low voltage ride-through state is analyzed in this paper, and a fault simulation platform is also founded. Three key factors have evident impact on transient short-circuit output are analyzed and compared, then a non-mechanism model structure determined by voltage drop is proposed. The segment strategy is adopted for short-circuit current modeling according to different level of voltage drop, and an optimized algorithm is designed for parameter identification.

To address this issue, the symmetrical phase-locked loop (PLL) has been proposed which can eliminate the frequency coupling and attribute the system model to be symmetrical. Although the system performances well under steady state, the characteristics of the inverter is unclear under non-ideal conditions at present. In this article, by investigating the inverter performance with the symmetrical PLL under different grid conditions, it is founded that both the dynamic and steady-state characteristics become worse compared to that with synchronous reference frame (SRF) PLL. The experiments validate the correctness of the theoretical analysis.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"42 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":"122303340","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}

When the induced voltage is too high, the human body will experience transient electric shock, so it’s necessary to limit the ground electric field. To address the problem of electric field effects on human body under AC transmission lines, the beetle antennae search algorithm (BAS) optimization charge simulation method (CSM) is applied to calculate the electric field distribution under EHV AC transmission lines, and the finite element method is used to analyze the effects of power frequency electric field intensity on human body under 500kV EHV AC transmission lines. The results show that the presence of the human body reduces the electric potential around it and the power frequency electric field will be strongly distorted at the human head. The distribution of the electric field and induced current density around the human body under 500kV AC transmission lines is quantitatively calculated to provide a reference for assessing the safety of the human body exposed to EHV AC transmission lines.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"96 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":"128765909","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}

This paper proposes a fixed cost allocation method for distribution network considering new energy access risk. Firstly, the state model and output probability model of each component of distribution network are established. Based on the non-sequential Monte Carlo simulation method, the probabilistic power flow calculation is carried out, and the node voltage-limited risk and active power-limited risk are obtained as the risk indexes of distribution network. The entropy weight method is used to calculate the weight of each risk index, and the comprehensive risk evaluation index is obtained. Finally, a model of equitable distribution of fixed cost among all responsible parties is established. Taking IEEE 14-bus system as an example, the risks and costs caused by different subjects of new energy are analyzed, so as to realize effective risk measurement and fair cost distribution to a greater extent.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"19 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":"125278967","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, because the AC side of the converter has a special current waveform with high harmonic content, the electromagnetic transient waveform of the vacuum OLTC switching process is very complex. The switching characteristics and breaking capacity of different OLTC transition circuit structures are very different, which directly affects the operating characteristics and life loss of vacuum OLTC for the converter. Therefore, this paper proposes an analytical method for the electrical stress of vacuum OLTC vacuum tubes for converters with different harmonic combinations, focusing on the analytical formula of switching the electrical stress of single-resistance transition circuit vacuum tubes, and then exploring the influence mechanism of harmonics on the switching characteristics of OLTC. The method can provide theoretical support and references for the structural design, parameter selection, and operation, and maintenance optimization of converter on-load tap changer in actual DC projects.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"254 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":"122732388","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}
