Acoustics offers a practical and effective means of identifying specific sound signatures associated with various faults without the need for sensors mounted directly on the machine. Stator unbalance faults (SUF) generate distinctive acoustic signals that can be analyzed to anticipate faults. Methods based on the intelligent classification of machine sounds give good results in this area. However, despite this progress, there is still a need to build up a more extensive database and better classify faults according to various ASM parameters. Precise characterization of the impact of each fault, both on the machine and its power supply, can facilitate the classification of malfunctions and contribute to earlier and more accurate diagnosis. The goal of this article is to study and characterize the acoustic signal of the ASM supplied by an unbalanced three-phase source or with one phase missing, by means of a statistical analysis (SA) of the acoustic data to detect the first signs of failure and facilitate their classification on the basis of acoustic and electrical measurements. This study reveals that the total harmonics distortion (THD) of the acoustic emissions (AEs) is more significant than that of the stator current, thus the statistical size parameters including the root-mean-square (RMS) and standard deviation (σ) are more significant than the shape parameters as the kurtosis coefficient (kurtosis).</div></div>","PeriodicalId":100488,"journal":{"name":"e-Prime - Advances in Electrical Engineering, Electronics and Energy","volume":"12 ","pages":"Article 100958"},"PeriodicalIF":0.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, various factors related to interconnected MG (IMG) infrastructure, such as the diversity of IMG architecture, economic viability, integration capacity, reliability, operational flexibility, and communication and protection schemes, can create great challenges in implementing efficient and resilient IMG infrastructure. Therefore, to address this concern, different IMG infrastructures are explored and analyzed to bring out the benefits, challenges, and constraints of the presented IMG architectures in this review. Accordingly, the concepts of IMGs and potential IMG architectures based on layout, line, and interface technologies are first discussed and compared. Then, numerous factors like cost, reliability, scalability, flexibility, complexity, and efficiency that play a significant role in evaluating the performance of IMG structures are identified to present a comparative analysis among various architectural topologies. All these analyses and comparisons are expected to serve as a reference in the field of IMG infrastructure to select a suitable framework based on the necessary functionalities.

The growing demand for grid decarbonization and changes in the resource mix have led to an increase in IBR adoption, mostly replacing conventional generators. IBR’s proliferation introduces more uncertainties to the operation of power grids, making it more challenging to maintain frequency or voltage stability and necessitating more robust grid stability decision support systems. Model-free artificial neural network-based solutions have been proposed to provide operators with situational awareness and decision-making capabilities during regular operations and contingencies. These solutions, however, may become inaccurate if their input system state is attacked, for instance, by falsifying input data or by noisy measurements. Therefore, a comprehensive support system that detects and responds to perturbed system states is essential for power system operators to rely on these solutions. This paper proposes an attack-resistant solution for assisting operators during Q-V scheduling circumstances using generative adversarial neural network (GAN) architecture combined with deep reinforcement learning (DRL). Voltage stability indices are incorporated into the proposed DRL framework to ensure the voltage stability of the grid. Using the modified IEEE 30-Bus transmission system, the proposed architecture is evaluated for different operational scenarios, and its ability to protect against falsified system states while facilitating voltage stability is demonstrated.</div></div>","PeriodicalId":100488,"journal":{"name":"e-Prime - Advances in Electrical Engineering, Electronics and Energy","volume":"11 ","pages":"Article 100940"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In constant power loads (CPL), when input voltage changes with respect to input current, the converter's performance in terms of power quality, dynamics, and stability are affected by the negative increment impedance characteristic (NII). Due to this, there is undesirable limit cycle behaviour in the system. The nonlinear passivity-based control technique (PBC) is employed to address this issue. The integrated converter system and PBC strategy are modelled using the Euler-Lagrange approach. The controller's resilience is tested under three different uncertainty conditions and robustness with different damping resistances. The PBC control approach ensures the elimination of limit cycles caused by the CPL, and ensures the stable system operation with faster recovery time of approximately 0.15 ss under uncertainty circumstances. The study further examined the PBC resilience across a range of active damping control gains (R<sub>3d</sub>=0.095 and R<sub>4d</sub>=0.045), and it is shown that lower damping gains give speedy recovery under the uncertainty conditions. A complete system with the proposed controller is simulated in a MATLAB environment, and validated results are presented.</div></div>","PeriodicalId":100488,"journal":{"name":"e-Prime - Advances in Electrical Engineering, Electronics and Energy","volume":"11 ","pages":"Article 100941"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143529859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
