Special Issue Information

Dear Colleagues,

Empowered by the ability of high-accuracy estimation and high-flexibility decision, artificial intelligence (AI) plays a crucial role in accelerating the decarbonization of power & energy systems. AI is capable of boosting the integration or renewable energies by predicting energy output, managing smart grids that adjust to supply and demand changes, predictive maintenance and dealing with extreme disasters. This Special Issue emphasizes recent advances in these areas and provides a platform for researchers and practitioners to share knowledge and discuss the latest developments. It aims to delve into various aspects of AI and power & energy systems. The topics of interest include, but are not limited to, the following:

  1. Energy generation forecasting using AI;
  2. AI based energy system dispatch and scheduling;
  3. Data-driven power & energy system state estimation;
  4. Predictive maintenance in power & energy systems using AI;
  5. Data analysis in cyber-physical system;
  6. AI for fault detection and diagnosis in power & energy systems;
  7. AI enhanced demand response;
  8. AI based methods of power & energy systems to deal with extreme disasters;
  9. Environmental impact assessment using AI;
  10. Other topics related to AI and power & energy systems.

State-of-charge (SOC) and temperature inconsistencies among lithium-ion battery cells can significantly degrade the performance, safety, and lifespan of battery packs. To address this issue, this paper proposes a dynamic balancing strategy that simultaneously regulates both SOC and cell temperature in real time. Each battery cell is connected to an individual Boost converter, enabling independent control of energy flow. An outer loop is adopted to stabilize the pack-level bus voltage. The balancing factors for SOC and temperature are adaptively fused using a Particle Swarm Optimization (PSO) algorithm, which dynamically adjusts the weightings based on real-time operating conditions. This approach allows the controller to prioritize either thermal or electrical balance when needed, ensuring robust performance under varying load and environmental disturbances. Simulation-based validation on a multi-cell lithium-ion pack demonstrates that the proposed method effectively reduces SOC and temperature deviation, improves pack-level energy utilization, and extends operational stability compared to fixed-weight balancing strategies.

Inter-turn short-circuit (ITSC) faults in permanent magnet synchronous machines (PMSMs) present a significant reliability challenge in electric vehicle (EV) drivetrains, particularly under non-stationary operating conditions characterized by inverter-driven transients, variable loads, and magnetic saturation. Existing diagnostic approaches, including motor current signature analysis (MCSA) and wavelet-based methods, are primarily designed for steady-state conditions and rely on manual feature selection, limiting their applicability in real-time embedded systems. Furthermore, the lack of publicly available, high-fidelity datasets capturing the transient dynamics and nonlinear flux-linkage behaviors of PMSMs under fault conditions poses an additional barrier to developing data-driven diagnostic solutions. To address these challenges, this study introduces a simulation framework that generates a comprehensive dataset using finite element method (FEM) models, incorporating magnetic saturation effects and inverter-driven transients across diverse EV operating scenarios. Time-frequency features extracted via Discrete Wavelet Transform (DWT) from stator current signals are used to train a Transformer model for automated ITSC fault detection. The Transformer model, leveraging self-attention mechanisms, captures both local transient patterns and long-range dependencies within the time-frequency feature space. This architecture operates without sequential processing, in contrast to recurrent models such as LSTM or RNN models, enabling efficient inference with a relatively low parameter count, which is advantageous for embedded applications. The proposed model achieves 97% validation accuracy on simulated data, demonstrating its potential for real-time PMSM fault detection. Additionally, the provided dataset and methodology contribute to the facilitation of reproducible research in ITSC diagnostics under realistic EV operating conditions. Full article
