Each CDC’s energy agent (CDCEA) minimizes the total CDC’s energy cost by optimizing its energy profile in response to dynamic locational marginal prices and the nodal carbon intensity of the power system issued by the independent system operator (ISO), who clears the energy market. CDCEAs integrate the on-site energy resources of CDCs, such as renewable energy and energy storage systems, and leverage the spatiotemporal flexibility of computing workloads through coordination with cloud service providers (CSPs). CSPs manage privacy-preserving workload scheduling and resource allocation by collaborating with associated CDCEAs and with other CSPs, while ensuring quality of service and adherence to service-level agreements. A two-stage optimization model is developed to coordinate decision-making between the ISO and CDCEAs in energy market in the first stage, and to address the coordination of CSPs with associated CDCEAs and other CSPs in the second stage. The proposed two-stage model is solved using a three-nested distributed iterative algorithm that combines privacy-aware hierarchical and peer-to-peer ADMM methods with an analytical target cascading (ATC) approach. The method is validated using a real-world case study in Northern Virginia, USA, demonstrating its effectiveness in reducing costs and enhancing sustainability.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"8658-8671"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011369","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}

The existing hybrid ANPC has advantages in terms of efficiency and cost, but it has inadequate loss optimization under varying operating conditions. To address this, a novel high-efficiency Si/SiC hybrid switch (HyS) topology coupled with a dual-current-path modulation strategy is proposed to reduce losses. The proposed converter topology effectively optimizes switching losses through a strategic implementation of four active HyS switches,when a novel modulation strategy concurrently reduces conduction losses by establishing dual current paths during zero state. The synergy between the two enables the proposed scheme to not only reduce the total loss but also achieve an effective distribution of conduction losses, thereby further enhancing the overall system performance. In this paper, the structural configuration and operational principle of the proposed topology are first analyzed, followed by the design of its corresponding modulation strategy. Subsequently, a comprehensive loss model is established to evaluate the loss characteristics inherent to the proposed topology and modulation strategy. Simulation studies are conducted to compare the loss distribution and efficiency performance among different ANPC schemes, highlighting the superior performance of the proposed scheme. Finally, a three-phase three-level HyS-based HANPC converter prototype is constructed and tested. Experimental results are presented to verify the enhanced performance of the proposed converter topology and modulation strategy.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"7425-7436"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011415","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}

The growing demand for electric transportation, coupled with inadequate charging infrastructure, is driving the adoption of the various RES options for battery charging. Among them, solar photovoltaics (PV) has great potential, especially as a portable/onboard green charging solution. To promote this green initiative, this paper proposes a dual PV-fed modified boost converter-based onboard battery charging scheme for E-rickshaw. The proposed scheme facilitates reduced semiconductor device count as compared to the state of art schemes. Further, the dual PV input feature enhances the utilization of available space on E-rickshaw, addressing the limitations of conventional single PV module-based solutions. The two PV modules, differently rated as per space available in rooftop and backside of E-rickshaw, can be operated at their respective maximum power points irrespective of their operating conditions. The proposed architecture enables simultaneous battery charging from two PV modules while also ensuring seamless operation in single-PV mode, thus maintaining uninterrupted charging even if one module is damaged or temporarily removed. Additionally, an integrated over voltage protection mechanism is incorporated into the control algorithm to safeguard the battery from excessive charging. A 420 W (250 W from top PV and 170 W from backside PV) power level laboratory prototype was developed, and detailed experimental validation of the system is carried out to ascertain its viability. The peak experimental efficiency obtained was 96.7%.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"7601-7611"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011193","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}

It proposes, for the first time, a tool for health monitoring and failure identification during thermal degradation effects in the insulation systems of stator coils from a concentrated stator winding. By periodical ex-situ inspection of these coils, the thermal ageing data of the insulation are profiled until the point of failure. The study maps this evolution of the thermal degradation pattern via novel interpretation of the differential-mode impedance frequency responses, using well known techniques such as the Bode and Nyquist plots. This grants further insight into the characteristics shown in the ageing profiles over time and frequency. These thermal failure profiles enable the identification of critical points that can act as pre-emptive indicators of coil health and failure inception. This is a key finding as it renders the capability to provide an adequate lifespan tool for electrical machine concentrated windings and coil assemblies in terms of remaining useful life and failure interpretation. The insulation system examined in this study is from the coils of the concentrated stator winding of a 2MW permanent magnet generator used in an aerospace application.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"7065-7076"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011206","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 study addresses the intraday scheduling of DCs under high-frequency fluctuations caused by renewable integration and load uncertainty. A carbon-aware bi-level optimization framework is proposed: the upper level clears the market based on electricity prices and carbon intensity, while the lower level minimizes the total operating cost, including electricity procurement, carbon emissions, and task migration costs. To overcome the real-time challenges of intraday decision-making, the problem is formulated as a Markov Decision Process (MDP), and a deep reinforcement learning (DRL) framework based on Proximal Policy Optimization (PPO) is developed. The agent interacts with the environment to dynamically adjust power procurement and task scheduling. The convergence and training stability of the proposed method are validated through representative learning metrics, including mean reward, explained variance, total loss, and value loss. Simulation results on a modified IEEE 5-bus system show that the approach outperforms traditional day-ahead strategies, reducing costs and emissions while enhancing spatiotemporal coordination. The PPO algorithm also exhibits a better performance than other benchmark DRL methods. Overall, the DRL-based carbon-aware scheduling strategy offers promising potential for advancing low-carbon and resilient power systems.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"8646-8657"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011333","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}

While prior studies address sustainable materials, energy harvesting, or transient electronics individually, existing literature lacks a unified model that simultaneously captures workload dynamics, renewable energy variability, and degradation-driven end-of-life behavior. To close this gap, the proposed architecture combines biodegradable substrates, ambient solar–thermal energy harvesters, and environmentally triggered dissolution mechanisms into a coordinated system that operates autonomously throughout its lifecycle. The framework formulates transient data center operation as a multi-objective optimization problem linking computational performance, harvested energy availability, and degradation-aware lifecycle control. A Non-dominated Sorting Genetic Algorithm III (NSGA-III) schedules workloads, allocates renewable energy, and regulates dissolution timing under fluctuating environmental and material conditions. This enables the system to maintain balanced operation without external power supply or manual supervision. Simulation results confirm the feasibility of self-powered biodegradable AI and blockchain micro-clusters, demonstrating improved energy utilization under constrained conditions, stable performance across variable workloads, and predictable, residue-free end-of-life dissolution. These findings establish a pathway toward zero-waste, energy-autonomous transient computing systems for disaster response, military missions, and other short-lived deployments.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"8611-8620"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011331","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}

Despite their advantages, the low and load-dependent output voltage of fuel cell stacks (typically below 200 V) requires high-efficiency boost DC-DC converters to achieve the DC voltage required by the traction inverters, usually in the range 400 V to 800 V. In this context, gallium nitride (GaN) technology enables switching frequencies exceeding 100 kHz, making it a prime candidate for power converters having high power density. This paper presents the design and experimental validation of a 75 kW interleaved multilevel DC–DC boost converter based on GaN power devices, developed to interface fuelcell stacks with 800 V traction inverters. Detailed characterization of the GaN switches is performed via doublepulse testing to properly evaluate the switching losses. This information is used for the thermal design of a liquidcooled heat sink ensuring safe operation below a 150 <inline-formula><tex-math>$^{circ }$</tex-math></inline-formula>C junction temperature. Magnetic design includes differential and commonmode inductors finiteelement analysis to meet ripple and powerdensity constraints. The DClink capacitor bank employs PLZT ceramic capacitors to minimize volume and losses. The assembled prototype achieves a volumetric power density of approximately 21 kW/L and a gravimetric density of 15 kW/kg. Dynamic load tests demonstrate a peak efficiency of 98.7% and robust current sharing and capacitor voltage balancing across all operating conditions.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"62 5","pages":"7539-7553"},"PeriodicalIF":5.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149011338","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}
