Pumped storage, as high-quality and flexible grid regulation resources, have played an increasingly prominent role in improving the optimization of resource allocation, maximizing the consumption of clean energy, and ensuring the safe and stable operation of the power grid on a larger scale. In order to promote the healthy development of pumped storage, it is stipulated that the capacity electricity revenues of pumped storage shall be included in the transmission and distribution price recovery. However, the document does not specify the specific allocation method, and how to improve the allocation method of capacity electricity revenues in multiple provincial power grids based on functions and services of pumped storage. This paper first establishes a comprehensive evaluation index of \"safety-environment-economy\" for pumped storage based on the functions and services conditions. Secondly, a comprehensive evaluation method for the capacity demand of pumped storage based on fuzzy analytic hierarchy process(abbr. FAHP)-entropy weight method(abbr. EWM)-technique for order preference by similarity to an ideal solution method(abbr. TOPSIS) method is constructed to analyze the capacity demand of pumped storage in various provinces and regions, and sensitivity analysis is performed. Finally, based on actual data from a certain regional power grid, the comprehensive demand for pumped storage capacity in various provinces and regions is determined through case analysis, providing reference for the allocation of capacity of pumped storage.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"1 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":"127235977","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 order to study the influence of harmonic current factors on the vibration characteristics of oil-immersed distribution transformers, this paper proposes a vibration simulation calculation method for the body of oil-immersed transformers based on Comsol Multiphysics finite element software. Taking the oil-immersed transformer model SFSZ11-25000/110 as the research object, firstly, the structure and vibration mechanism of the power transformer are analyzed theoretically and the equivalent mathematical models of transformer winding and core are established respectively. Then, based on the geometric model and internal structure of the oil-immersed transformer, we modeled the solid model and analyzed the influence of harmonic current on the vibration acceleration and stress field of the transformer based on the multi-physical field coupled vibration model of electric-magnetic-structural force field. The analysis results show that the average flux density of the transformer core increases slightly with the increase of superimposed harmonic current content, but the increase of the average flux density of the core is not significant with the increase of the harmonic current frequency. At the same time, the transformer winding current changes significantly after the injection of harmonics, and the effective acceleration of the transformer winding increases gradually with the increase of the superimposed harmonic current content and harmonic frequency, and the stress on it increases by two orders of magnitude compared with the fundamental wave condition.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"30 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":"127470485","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, it is ubiquitous that the performance of the equalizer with the concentration structure in the balancing speed and accuracy is poor. To solve the problem of poor balancing speed and accuracy in the traditional equalizer with the concentration structure, a multi-state and energy path equalizer is proposed, which can realize the inside-to-inside (I2I) charge transfer, outside-to-inside(O2I) and the inside-to-outside (I2O) charge transfer. It allows the proposed equalizer to achieve a faster balancing speed and higher accuracy.

Based on phase analysis, this paper proposed a new method for obtaining the resistive current of MOA. By taking into account the effect of inter-phase coupling capacitance and the third harmonic in power system, a model of three-phase MOAs operated at the 10kV was created in MATLAB for the resistive current calculation under different conditions.

As electricity demand can influence the development of solar thermal power, electricity demand forecasting is also considered. We simulated the development of solar thermal power generation in a certain region. The simulation results shows that, in the base scenario, the cumulative installed-capacity of solar thermal power generation will reach 2.68 and 19.7 million kilowatts in 2030 and 2060, respectively.

FTUs are installed at the detection points to collect three-phase current and upload it to the master station to synthesize zero-sequence current. The master station determines the fault section by comparing the cosine similarity of zero-sequence current between FTUs.

SF assessment based on conventional electro geometric model (EGM) ignores the physical process of lightning progression and the influence of operating voltage. Therefore, it still leads to an underestimation of the shielding failure rate (SFR), which brings risks to the safety of TLs operation. In this paper, a numerical model of lightning attachment to 1000 kV double-circuit UHV-AC TLs based on the self-consistent leader inception and propagation model (SLIM) and FEM was developed. The downward leader was considered as a lossy conductor approaching the ground vertically at a constant velocity. The streamer charge and streamer length at the front of the upward leader were calculated using voltage distortion method (VDM). The process of lightning attachment to the TL has been simulated. In addition, the effect of the operating voltage of the phase conductors on the lightning attachment process was analyzed. The simulation results revealed that when the operating voltage was 0, only the upward leader can be generated on the GW. After the phase conductors charged with voltage, upward leaders may be generated on the GW and the upper phase conductor at the same time, which increased the SF risk of TLs. The upward leader on the GW has strong shielding effect on phase conductors, which inhibits the propagation of upward leader on phase conductors. For the upper phase conductor, the risk of SF appeared at the time when the voltage phase angle was 0°, 135°, and 270°.","PeriodicalId":231392,"journal":{"name":"2023 IEEE International Conference on Power Science and Technology (ICPST)","volume":"2015 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":"127787617","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}
