The study presents a framework that integrates a recently developed dry deposition based soiling losses assessment model with an energy- economic criterion for enabling decision making to derive manual cleaning strategies for solar photovoltaic systems installed in urban environments. The dry deposition model links local air quality and meteorological factors to determine the dust accumulation, allowing realistic estimation of soiling behaviour under diverse urban conditions. The framework was tested to evaluate the site-specific variations in soiling losses and different cleaning strategies under varying costs across 22 sites situated in two Indian cities. Daily automatic cleaning was also evaluated as a realistic scenario, and its economic viability was assessed. Soiling rates ranged from 0.33–0.63% /day in Jaipur and 0.37–0.95% /day in Delhi, with higher averages in Delhi, indicating the inter and intra city variability of soiling influenced by the localized urban pollution and climate. At a lowest manual cleaning cost of ₹4/panel, optimized schedules required 15–21 cleanings in Jaipur and up to 30 in high-soiling Delhi sites. The study offers data driven insights on how localized environmental conditions affect soiling accumulation and thus, cleaning requirements in diverse urban photovoltaic deployments. The proposed framework serves as operational guidance for urban solar energy planners to enhance the “energy-economic benefits” of small- to medium-scale power plants where automated solutions may not be feasible.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"7766-7776"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011221","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}

Effective energy management can mitigate these emissions by scheduling training workloads during periods of lower carbon emission factors (CEFs). During model training, optimal training progress is guided by future CEF forecasts and achieved by configuring GPU servers. However, existing energy management methods depend on fine-grained CEF forecasts for the entire multi-month training period, which is highly challenging in practice. Additionally, the large number of discrete decision variables introduced by GPU server configuration further complicates optimal energy management. In this paper, we propose a long-term energy management method for large model training. To eliminate numerous discrete decision variables in GPU server configuration, we first construct a linear aggregated energy model for the GPU cluster using the Progressive Vertex Enumeration (PVE) algorithm. To avoid dependence on fine-grained CEF forecasts for the entire training period, we apply dual decomposition to decompose the scheduling problem into daily subproblems and estimate future carbon emissions of deferred training batches using a neural network with coarse-grained mid-term forecasts. Experimental results demonstrate that our approach reduces total carbon emissions by 5.9% compared to baseline methods.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"8400-8413"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011347","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 presents a modular multiport SST topology designed to deliver power to low-voltage ac (LVac) and low-voltage dc (LVdc) ports from medium-voltage ac (MVac) and medium-voltage dc (MVdc) ports. The proposed SST architecture employs a modular multilevel converter (MMC), a quadruple active-bridge (QAB) converter with a high-frequency transformer, and a two-level voltage source inverter. The MMC generates a stable dc-link voltage from MVac and MVdc inputs, while the QAB ensures galvanic isolation and voltage step-down to the LVdc level using fewer components. The final LVac output is achieved through an efficient two-level voltage source inverter stage. An advanced modulation technique is implemented to reduce total harmonic distortion (THD) and enhance the efficiency of the inverter. Simulation studies conducted in MATLAB/Simulink confirm that the proposed multiport SST maintains quality power across all ports and meets IEEE standards. Additionally, power losses and efficiency of the inverter are evaluated using the PLECS simulation platform. Results show a significant improvement, achieving 50.48% THD and 84.26% efficiency of the inverter at unity modulation index and 10 kHz operating frequency, outperforming conventional approaches. Experimental validation using a reduced-scale prototype further verifies the practical viability and effectiveness of the proposed SST system and modulation technique.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"8319-8332"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011327","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}

Nevertheless, one critical issue for TAB converters is the high-frequency transient dc-bias current (HFTDC) due to the volt-second imbalance under various dynamic conditions such as the startup, power reversal, and sudden load or output voltage change. Main consequences resulting from HFTDC include increased current stresses, causing magnetic saturation of the converter and posing a risk of damage to power electronics components. After reviewing main strategies of suppressing HFTDC especially for complicated TAB converters, a general mathematical model of TAB converters was developed and consequently a universal HFTDC suppression strategy based on flux-balancing principle and superposition analysis was proposed. The proposed strategy can effectively realize the power decoupling and lower the implementation difficulty. In addition, the advantages of the proposed strategy are also reflected in its versatility for various modulation techniques, as well as its ability to adapt to various dynamic scenarios, including load changes, power fluctuations, power reversal, and startup processes.

As a case study, the transient performance of a 60 V clamping-type bidirectional transient voltage suppressor diode is evaluated under electromagnetic pulses with varying frequency and energy content. To address the challenges associated with conventional modeling approaches of manufacturers’ models, a simplified model is proposed. ATP-EMTP simulation results demonstrate that the proposed model quite accurately predicts the transient behavior of the bidirectional transient voltage suppressor diode under both standard and non-standard impulse current conditions, covering a broad range of peak currents (5 A–13.5 kA), wavefront durations (0.9–10 µs), and time-to-half values (20–350 µs). The proposed modeling approach, yielding errors lower than 10% on maximum residual voltage, and energy stress offers a practical tool for electromagnetic transient simulations, supporting the design and dimensioning of surge protection schemes involving transient voltage suppressor diodes aimed at ensuring the reliable protection of sensitive emerging DC systems and smart grids. Electromagnetic transient simulations of a lightning strike at a cellular radio site are carried out to demonstrate the implementation of the proposed TVS model and to evaluate its transient performance against the manufacturer’s model.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"8237-8248"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11442680","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011254","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}

Unlike existing approaches, the proposed method estimates the vibration amplitude in real time based on the excitation voltage and current, and adaptively adjusts the control parameters using a compensation coefficient derived from the ratio between the initial and regulated voltages. This eliminates the reliance on accurate system models or external sensors. After voltage regulation, the controller ensures both phases have equal amplitudes to maintain a stable traveling wave. The proposed strategy effectively compensates for steady-state nonlinear disturbances and adapts to variations in motor parameters, ensuring robust and high-precision real-time tracking performance. Extensive comparative simulations and prototype experiments validate the superior capability of the proposed method in suppressing periodic fluctuations and enhancing motor speed stability, demonstrating its practical applicability and robustness.

In previous works, reinforcement learning (RL)-based formulations have led to APC methods that can be deployed to multiple radial grids without re-training. This is achieved by reducing the action space from nodal curtailments to uniform per-feeder curtailments, lowering the amount of required training data, albeit with a potential trade-off in performance. To address the latter issue, in this paper, low-complexity APC strategies are developed that disaggregate the uniform per-feeder curtailments over the buses, while relying only on limited and coarse grid model information and preserving the generalization properties. The proposed per-bus APC approaches involve training the uniform per-feeder RL controller considering disaggregation in the environment. In addition, a heuristic generalizable APC controller that does not depend on the uniform per-feeder actions is developed. All proposed APC controllers are thoroughly evaluated and compared as well as benchmarked with respect to optimal power flow solutions. It is demonstrated that disaggregation significantly improves the performance of the uniform per-feeder RL-generated actions in terms of trading-off violations with curtailments. Importantly, the adaptability of the proposed APC controllers to unseen grids without re-training or re-tuning is showcased.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"7688-7700"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011361","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}
