Energy efficiency is an important factor affecting the application of power to hydrogen (P2H) in power systems. The power quality of the rectifier and the operating temperature affect the energy efficiency of the electrolytic cells. This paper reveals the combine impact of the power quality and operating temperature on the energy efficiency of proton exchange membrane electrolytic cells (PEMEC). Firstly, the P2H PEMEC test platform is built, the model of PEMEC is established base on the test data. Secondly, with the different rectifies, the harmonic distribution and the ripple factors on the energy efficiency of the PEMEC are studied.

At present, around 20 SFCLs are installed worldwide. All these SFCLs have custom design and are specifically tailored to installation site specifics. This may limit widespread application of this technology since each new SFCL installation requires different design and—as a result—multiple approvals from numerous parties (utilities, government, etc.), which is a labor-intensive and time-consuming process. To reduce the efforts required for equipment approval, electrical industry developed an extensive system of standards, and thus, it is necessary to explore the possibility to create an SFCL, which complies with the existing standards. This article examines the existing regulations for the closest to SFCL equipment, i.e., current-limiting reactors, deduces the possibility of applying these regulations to the existing SFCLs, provides requirements that SFCLs are yet to satisfy, and, finally, estimates the basic technical specifications of SFCL that should comply with all the requirements studied.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"34 9","pages":"1-8"},"PeriodicalIF":1.7,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimization designs of two DSPMMs are analyzed by establishing the equivalent magnetic circuit (EMC) models at no load and load conditions. Another two traditional DSPMMs (topologies III and IV) are taken as the comparison objects, and the best optimal structure parameters of the four topologies are decided by genetic algorithm. A prototype of topology II is manufactured, and the electromagnetic performances of the four DSPMMs are revealed. It is observed that the electromagnetic performances of topology II analyzed by EMC method are in agreement with the results analyzed by finite element method and test results, and the torque of topology II is larger by 148.1%, 27.72% and 245.5% than that of topology I, III and IV, respectively.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"34 8","pages":"1-5"},"PeriodicalIF":1.7,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A pivotal element in this coordination is the multi-agent coordinator, strategically positioned as an intermediate controller between the primary and tertiary control levels. Its role is to derive optimal setpoints from data obtained at the tertiary control level and convey them to the relevant agents at the primary control level. This study presents a novel optimization model for the multi-agent energy management system, aimed at enhancing real-time economic dispatch in the secondary control by managing active and reactive power. Instead of relying on a conventional centralized MG controller, the proposed framework employs multi-agent coordination to improve the reliability, stability, and economic performance of MG operations.","PeriodicalId":13104,"journal":{"name":"IEEE Transactions on Applied Superconductivity","volume":"34 8","pages":"1-5"},"PeriodicalIF":1.7,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Input parallel output series (IPOS) DAB converters are capable of broadening the output voltage range and output power level, of which the output voltage balancing control is essentially required. In this article, based on the generalized power model and characteristics of cooperative triple phase shift (CTPS), a self-adapting voltage balancing method is proposed for IPOS DAB converters to strike a balance between wide output voltage and small transient oscillation. Moreover, by employing the proposed method, IPOS DAB converter is able to achieve quasi no reverse power of dual sides by using single current control loop, which helps in reducing the complexity of control loop design and lowing the computation burden.

The skin depth is included in the equations of the classical eddy current field intensity considering the inhomogeneous distribution of the magnetic field under high frequency excitations. Besides, the DC-component of the excitation is also considered in the derived classical eddy current field equation. The nonlinear property of magnetic materials is accounted by discussing the saturated and the unsaturated operating conditions separately. The measurement results of a typical GO silicon steel are applied for the validation of the proposed dynamic hysteresis model.

A positive correlation between motor efficiency and the number of poles is demonstrated through a finite element simulation on disk motors with different pole numbers.
