Special Issue Information

Dear Colleagues,

The possession of intelligent operation and control capabilities for sustainable power and energy systems has become an urgent necessity to ensure high efficiency, reliability, and safety. This trend requires the development and implementation of electromechanical smart devices, digital modeling, and new methodologies in artificial intelligence and predictive analytics. Sustainable energy systems encompass electromechanical energy conversion systems and renewable generation, such as wind turbines, which lead to complex dynamic behavior and operational challenges, requiring advanced approaches in automation, control, and condition monitoring and diagnostics. Furthermore, the integration of renewable energy into the power grids requires further development of intelligent control, fault management, and cybersecurity techniques for both the grid and individual apparatuses, including electrical machines such as generators and transformers.

This Special Issue aims to bring together high-quality contributions that highlight recent advances in intelligent operation, monitoring, fault detection and diagnosis, self-healing mechanisms, and cybersecurity with a particular emphasis on sustainable power and energy systems. It seeks to showcase the application of novel theories and methodologies across various domains to enhance operational management and automation. Contributions that include practical implementation and experimental validation are especially encouraged.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Fault detection, diagnosis, and predictive maintenance of electrical machines and electromechanical energy conversion systems.
  • Multiphysics and AI-assisted modeling of electromechanical and renewable energy systems.
  • Renewable energy integration, grid coordination, and advanced automation strategies.
  • Digital Twin and data-driven modeling for real-time monitoring and intelligent control.
  • Self-healing and resilience strategies for renewable-integrated power grids.
  • Optimization techniques for energy efficiency, dynamic performance, and intelligent operation of sustainable energy systems.
  • Cybersecurity and secure control architectures for sustainable power systems and smart grids.

Maximum power point tracking (MPPT) is a critical function for maximizing energy extraction in photovoltaic (PV) systems. Due to the inherently dynamic nature of the maximum power point under varying irradiance conditions, achieving fast convergence, low steady-state oscillations, and high tracking efficiency remains a challenging research problem. This paper proposes a hybrid ANN-based MPPT strategy for photovoltaic systems operating under rapidly changing environmental conditions. The proposed approach integrates a rule-based operating-condition estimation stage with a recurrent ANN-based control stage, enabling adaptive duty-cycle generation using measured PV voltage and current signals. Unlike conventional MPPT techniques, the proposed method utilizes operating-region estimation together with an extended ANN input feature vector and a recurrent backpropagation neural network to improve dynamic tracking performance under abrupt irradiance variations. In addition, a composite loss function is adopted to enhance tracking accuracy, guidance consistency, and control smoothness. The ANN is initially trained offline and subsequently refined online using lightweight incremental adaptation to maintain effective operation with a low computational burden. The proposed MPPT strategy is evaluated against P&O, FLC, and SMC. Simulation results demonstrate improved tracking performance, faster dynamic response, and reduced steady-state oscillations under abrupt irradiance variations. Full article
