With the increasing electricity demand, power transmission lines continue to grow and become increasingly complex. Because even the smallest faults occurring on growing power lines can impact the grid, rapid fault detection, classification, and subsequent repair are crucial. In this study, a new Machine Learning approach based on the Autogluon framework is proposed for rapid fault detection and high-accuracy classification of transmission line faults. Three different methods are employed within the Autogluon framework, and the results are evaluated and compared using ROC analysis. The first method uses the original dataset containing 7861 data points obtained from the open-source Kaggle platform. The second approach adds statistical properties of current and voltage values (mean, standard deviation, and range) to the original dataset. The third method uses the SMOTE algorithm to generate synthetic data and increase the data size to address the imbalance in the number of fault classes in the dataset. The proposed method demonstrates the critical role of data processing and feature engineering in optimizing classification performance and achieving the most accurate diagnosis for multi-label fault classification. The numerical results compared with the literature show that the proposed method is promising for practical applications.

With growing global energy demand, ensuring a reliable energy supply is critical for all nations. The modern Energy services in residential buildings, especially those using combined cooling, heating, and power (CCHP) systems, are particularly important in meeting these demands. Accordingly, this study focuses on day-ahead energy management in a smart CCHP grid with the participation of hybrid energy storage systems and optimal energy consumption by consumers in smart residential buildings. The energy management is modeled by a multi-level and multi-objective optimization approach considering demand response strategies (DRSs). The DRSs include electrical demand shifting of power consumption, and self-generation of power, and gas storage systems. The electrical demand shifting strategy is implemented in the first level optimization, subject to electricity pricing traffic to minimize consumers’ bills. Also, minimizing consumers’ bills in the second level optimization is done by power and gas storage systems via the local self-generation (LS-G) strategy, subject to electricity and gas prices in the energy market. In the third level optimization, multi-objective functions like minimizing operational costs, maximizing flexibility and minimizing power losses are implemented. In the proposed optimization approach, optimized energy consumption in the first and second levels is considered in the third level optimization. The proposed optimization approach for all levels is solved by using General Algebraic Modeling System (GAMS) software. In the following, solving multi-objective optimization approach in the third level is carried out by enhanced epsilon-constraint method. Also, Shannon Entropy decision making method is proposed for determining optimal solution in third level for multi-objective functions and Pareto front solutions. Finally, the findings show the optimal results of the objectives at each level and highlight consumer involvement through a comparative analysis via various case studies. The participation of DRSs leads to a 11.63 % reduction in operational costs and 18.75 % reduction in power losses, while also enhancing flexibility by 2.6 % in the CCHP grid.

The next-generation smart grid requires a unified computing framework that seamlessly integrates communication, high-performance computing (HPC), and AI to enable real-time energy perception, forecasting, and decision-making. Conventional architectures, which treat communication, computation, and control as independent modules, often suffer from latency, scalability limitations, and weak coordination across heterogeneous infrastructures. To overcome these constraints, this work proposes an energy-efficient unified computing framework where communication networks, HPC clusters, and AI orchestration operate as a tightly coupled ecosystem. AI modules handle deep learning–based perception of multi-source energy data and employ reinforcement learning to optimize dynamic load allocation and demand-side flexibility. Superscale HPC resources accelerate renewable forecasting, grid stability assessment, and large-scale optimization tasks. In parallel, adaptive communication units with edge-level compression and intelligent routing ensure low latency and resilience under varying network loads. The framework is evaluated through MATLAB/Simulink and Python co-simulation using HPC-enabled TensorFlow clusters and blockchain-secured IoT gateways. Experimental results demonstrate a System Orchestration Index (SOI) of 98.3 %, a Computational Efficiency Ratio (CER) of 37.5 %, a Demand Flexibility Index (DFI) of 33.8 %, and an end-to-end decision latency of 18 ms. Compared with conventional grid computing approaches, the proposed architecture achieves improvements of 9.4 % in orchestration efficiency, 7.8 % in computational efficiency, and 6.2 % in demand flexibility. These outcomes highlight the potential of an AI-driven, HPC-accelerated, and communication-adaptive unified computing paradigm for scalable and resilient smart grid operations.

Frontier scientific and AI workloads now reach fused multiply–add (FMA) operations per run (on the order of FLOPs). At today’s pJ per FMA, this corresponds to approximately joules of arithmetic energy. At this scale, energy becomes the limiting resource for continued growth in computational workloads, motivating a re-evaluation of long-standing algorithmic assumptions. It is often assumed that reversible computing only matters near the Landauer limit. Building on prior physical arguments that full energy recovery is only possible when computation preserves information, we demonstrate that this same requirement governs floating-point numerical kernels: overwriting state enforces a non-zero energy floor, even under ideal recovery. Thus, eliminating this wall in practice requires that the numerical algorithm itself be injective. We therefore present the first reversible floating-point realizations of core dense numerical kernels—matrix multiplication, LU factorization, and conjugate-gradient iteration—that retain rounding information rather than discarding it. Implemented directly in IEEE arithmetic, they achieve machine-precision forward–reverse agreement on well- and ill-conditioned problems with minimal auxiliary state. A toggle-based model with measured switching costs and realistic recovery factors predicts reductions in arithmetic energy. These results establish injective floating-point kernels as a foundation for energy-recovering numerical computation, and indicate that realizing this potential will require sustained co-design across applied mathematics, computer science, and hardware engineering.

The growth of the penetration of distributed renewable resources has enhanced the need to have secure, scalable, and energy-efficient P2P (peer-to-peer) energy trading in microgrid settings. Conventional centralized market systems and aggregator-based trading systems can be limited by privacy leakage, high costs of communication, and single points of failure, which restrict them in the scalability of decentralized environments. The proposed blockchain-enabling federated learning (FL) framework that is suggested in this paper will aim to optimise P2P energy exchanges in microgrids to mitigate the limitations of the existing approach. Smart meters based on the Internet-of-Things record data on generation and consumption, which is locally computed to learn federated models without revealing raw information about users. The FL module uses gradient sharing together with adaptive aggregation to optimize the exchange decisions among prosumers, and the blockchain component can guarantee trade settlement with tamper-proof and the contract enforcement through proof-of-stake consensus mechanism that is based on lightweight cryptography. Moreover, edge-level compression of data and incentive sensitive participation schemes minimize communication costs and encourage fair participation in the market. Experiments of performance measurements on a MATLAB/Simulink-TensorFlow co-simulation model with Hyperledger Fabric show trading efficiency of 95.7 % and 27.6 % energy savings improvement, throughput of 174 transactions per second and 31 % communication overhead reduction compared to centralized and non-blockchain FL schemes. The findings support the ability of the proposed system to provide privacy preserving, energy saving, and safe P2P energy transactions in next-generation decentralized microgrid ecosystems.

In this paper, we present a reproducible pipeline to benchmark the trade-off between carbon emissions and recommendation performance across 14 algorithms and three publicly available datasets. In particular, we contribute: (a) a standardized protocol to account for carbon emissions of recommendation algorithms; (b) an empirical quantification of the carbon cost of hyperparameter tuning, and (c) an evaluation of data-reduction strategies as a low-cost approach to reduce emissions while improving certain non-accuracy metrics. Unlike previous literature, which mainly focused on the trade-off between performance and emissions, our benchmark reveals the cost of hyperparameter tuning. It examines the impact of data reduction techniques on the path toward sustainability-aware recommender systems. Our results show that simpler algorithms often deliver competitive accuracy at significantly lower emissions, and that exhaustive tuning can dramatically increase carbon costs with limited accuracy gains. Generally speaking, this study aims to discuss the challenges of energy consumption in recommender systems and to develop a new generation of algorithms that prioritize sustainability. All code and experiment traces are publicly released for reproducibility on Github.1

The Internet of Underwater Things (IoUT) is revolutionizing maritime research, environmental monitoring and intelligent aquatic applications with real-time sensing and communication. Energy-efficient communication is the biggest challenge because of the constraint of bandwidth, long delay of propagation and highly dynamic water channels. To combat these issues, AquaSense-AMC is introduced a new Adaptive Modulation-Control (AMC) Model for underwater IoT networks. The framework provides three novel components: Channel-Aware Modulation Switching (CAMS), dynamically switching between modulation depth and symbol rate based on channel fluctuations; Energy-Constrained Control Mechanism (ECCM), energy-optimizing transmission power with predictive energy management to maximize node lifetime; and Hybrid Acoustic-Optical Relay (HAOR), a two-mode relay scheme that integrates acoustic links for extreme distance reliability with optical links for high-rate near-distance data transfer. Experimental assessments prove that AquaSense-AMC saves energy by 28 %, enhances packet delivery ratio by 35 % and increases network lifetime by 22 % relative to baseline methods. The model implements a sustainable and adaptive communication system and making IoUT operation reliable and energy-efficient in intricate underwater environments.

Wireless Sensor Networks (WSNs) enable large-scale data collection through spatially distributed sensor nodes but face challenges due to limited energy, computational capacity, and security vulnerabilities. Traditional routing protocols optimized for wired networks are unsuitable for such constrained environments. This paper presents an Energy Efficient Secure Routing Protocol (E2SRP) for edge-assisted WSNs, addressing both energy consumption and security concerns. Trust values are computed using the Analytical Hierarchy Process (AHP) based on Direct, Indirect, and Witness Trust metrics to ensure reliable node selection. Optimal routing paths are identified through the Grey Wolf Optimization (GWO) algorithm, while BLAKE3 hashing performs secure data aggregation and deduplication at the edge. Additionally, Fuzzy Intelligence supports load balancing to enhance system stability. Simulation results using NS-3 demonstrate that the proposed model significantly improves Packet Delivery Ratio (PDR), reduces energy consumption and routing overhead, and strengthens overall security resilience compared with existing methods.

The microgrids function as distributed energy systems using renewable energy sources such as solar, wind, and energy storage. Microgrids have tremendous possibilities to improve an energy system in terms of resilience and sustainability. This paper essentially deals with describing an AI-based energy management system tailored for optimizing the operation of the renewable energy-powered microgrid. The EMS uses advanced ML techniques consisting of LSTM networks for forecasting, DQN for decision-making, and Random Forest depending upon solar energy forecasting. The models were tested on several benchmark datasets, namely, renewable, solar, wind, and a global energy dataset. According to the results, the model with LSTM gave the best forecasts, particularly for the Wind Energy Dataset (R 2 = 0.9955). On the other hand, the highest performance for the Solar Energy Dataset was obtained by a random forest, which gave it a lesser predictive power radius than other techniques (R² = 0.827). The other energy datasets also witness optimal working of LSTM time-series approaches, giving much smaller errors for training and validation phases. Moreover, AI-assisted EMS, given improved energy resource optimization, forecasting, and operational resilience, will play a vital role in managing renewable microgrids under dynamically ever-changing and uncertain environments. This study also endorses the application of AI in furthering and passing good genes of efficiency, sustainability, and fault tolerance into renewable-powered microgrids.
