However, due to their lack of maturity, PPCs still require an extensive analysis of their reliability. Despite their capability of varying the voltage level between its terminals, similarly to a power transformer, they cannot provide galvanic isolation between both sides. Then, in the event of a ground fault, the entire system becomes highly exposed. Therefore, this paper presents a ground fault detection method for PPC-based solutions. The approach relies on a grounding resistor that is sequentially linked between the positive, negative, and midpoint terminals of the DC systems, grounded by three different switches. The paper provides a detailed explanation of the methodology and the necessary components to perform the diagnosis. A simulation setup conducted in MATLAB-Simulink is presented, along with its results. Afterwards, an experimental 50-kW Input-Series-Output-Parallel PPC test bench is used under both healthy and faulty scenarios to validate the methodology. The results conclude that this method not only detects the ground faults, but it also discerns its location, reducing the maintenance work.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 5","pages":"8170-8182"},"PeriodicalIF":4.5,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10967058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144867704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings confirm IS as a promising tool for on-field applications, especially in small-scale urban power plants where partial shading is a common issue. An analysis of several experimental impedance spectra measured with PV panels operating at their Maximum Power Point (MPP), with controlled partial shading conditions, reveals that partial shading induces a characteristic double-arc deformation. This feature could be leveraged in a diagnostic tool for mismatch detection. The key advantage of this approach is its ability to perform IS measurements at MPP, preserving the normal operating conditions of the PV panels/string/array. Additionally, IS requires minimal modifications to the system's architecture and integrates easily into existing power electronics interfaces. To validate the consistency of impedance spectra under partial shading, experimental data were compared with two models: a Constant Phase Element (CPE) model adapted for PV strings in non-uniform conditions and an enhanced Single-Diode Model (SDM) developed for SPICE3-based simulations. The results confirm that IS successfully adjusts the models and detects mismatches in both experimental and simulated scenarios, demonstrating its scalability and effectiveness as a state-of-the-art PV diagnostic tool.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 5","pages":"7584-7597"},"PeriodicalIF":4.5,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144867733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the control performance of MPPC may deteriorate due to a mismatch between the system model and the actual system. To address this issue, online parameter identification can be used as an alternative method to model refinement. In this paper, an MPPC method based on recursive extended least squares (RELS) is proposed to improve the trajectory tracking performance of a laboratory-developed PSRM system. The conventional dynamic model and RELS-based parameter identification dynamic model for the PSRM are established. The predictive model is developed using the parameter identification dynamic model, with its parameters updated online. The control law is derived from the developed predictive model and the defined cost function, and the system stability is subsequently analyzed. The simulation and experimental results show improvement in the trajectorytracking performance of the PSRM system.

Electric vehicle chargers integrate with distribution networks via power electronic interfaces, offering significant control and operational flexibility. The industry is quickly adapting to this rapidly emerging load type, and now requires a robust means for understanding their impact on power system operations. This paper presents a modeling approach to capture the aggregate dynamic impact of these chargers on the power system in response to a range of network fault conditions. Six commonly available electric vehicles were empirically tested under various supply disturbances using a grid simulator, and their fault ride-through performances have been characterised. The undervoltage withstand capability of the six vehicles varied considerably, with fault voltage thresholds ranging between 0.3 and 0.7 pu leading to electric vehicles either ceasing charging for between ∼2 and 10 seconds, or locking out completely. A composite dynamic load model for electric vehicles was developed and validated, employing the collected empirical data. The validation process demonstrated the aggregate load model's capability to accurately capture the resulting load deficit owing to electric vehicle fault ride-through in response to transmission-level faults. The proposed model is suitable for application in wide-area power system studies to enhance the accuracy of simulated network load response for frequency assessments, operations planning, and other system analyses.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 5","pages":"8051-8063"},"PeriodicalIF":4.5,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144867710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a novel rotor structure featuring inclined through holes, which based on forced air-cooling method. On the one hand, the through holes provide additional flow paths for cooling air, effectively reducing flow resistance. On the other hand, as the rotor rotates, a pressure difference is created between the two ends of the holes, which generates the airflow independently. To accurately calculate the flow and thermal fields, three-dimensional (3-D) computational fluid dynamics (CFD) models have been established. Using the basic design of a 1.5 MW MS-PMSWG, a comparative analysis is conducted between the conventional structure and the proposed design. Under rated operational condition, the pressure required for the cooling fan to generate the same flow rate is significantly reduced by the adoption of the proposed holes, as well as the temperature rises of the windings and permanent magnets are reduced. Moreover, under the fault condition with the fan shutdown, the operational capability is greatly enhanced, attributing to the airflow generated by the rotating holes. Furthermore, reduced scale prototypes are built adhering to the principles of Reynolds similarity, and the effectiveness of the proposed structure is experimentally validated.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"61 5","pages":"7072-7083"},"PeriodicalIF":4.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
