Power utilities are increasingly employing EVs with dynamic energy storage for ancillary services such as frequency and voltage regulation. Additionally, EVs are utilized for dynamic damping services, where grid-connected EVs help mitigate frequency oscillations in weak grid conditions. This work presents a novel modified automatic voltage regulator (AVR)-integrated fuzzy logic-based control of EVs, incorporating a feedforward term to enhance damping services. A finely tuned AVR in a conventional generation improves synchronizing and damping torque for frequency oscillations. In this work, a modified AVR control loop is designed, combining the battery characteristics with linear controllers to generate additional damping vectors for frequency oscillations. Furthermore, an intelligent rule-based fuzzy logic (FL) controller is developed to replicate the traditional virtual synchronous control, enhancing the overall inertia and damping response. The proposed approach is validated using a modified IEEE 14-bus system under different case studies, such as load changes, EV variability, and integrated system dynamics. The results demonstrate superior performance over conventional droop control, achieving reduction in steady-state error, peak overshoot, and settling time.

This shift has significantly reduced rotational inertia, increasing the system’s vulnerability to frequency fluctuations during disturbances. Consequently, the accurate and adaptive estimation of inertia has become crucial for maintaining frequency stability and grid reliability. Traditional estimation methods, though effective in certain scenarios, struggle to capture the non-linear and dynamic behaviors of modern power systems, necessitating the adoption of advanced solutions. This review comprehensively explores machine learning (ML)-based methodologies for inertia estimation, emphasizing their adaptability, scalability, and real-time capabilities compared to conventional approaches. The study categorizes ML techniques into supervised learning (SL), unsupervised learning (USL), semi-supervised learning (SSL), and reinforcement learning (RL), highlighting their applications, advantages, and limitations. Advanced methodologies, such as hybrid and ensemble models, are examined for their effectiveness in overcoming challenges posed by noisy data, dynamic behaviors, and complex grid configurations. Some advanced techniques demonstrate proficiency in analyzing complex datasets and providing real-time insights into the evolving dynamics of inertia. In addition to evaluating existing approaches, the review identifies key research gaps and emerging trends, offering strategic guidance and important considerations for the development of innovative ML-driven inertia estimation methods.

The largest potential of NILM lies in industrial applications facilitating key benefits like energy monitoring and anomaly detection without excessive submetering. However, besides the lack of feasible industrial time series data, the key challenge of NILM in industrial applications is the scarcity of labeled data, leading to costly and time-consuming workflows. To overcome this issue, we develop an active learning model using real-world data to intelligently select the most informative data for expert labeling. We compare three disaggregation algorithms with a benchmark model by efficiently selecting a subset of training data through three query strategies that identify the data requiring labeling. We show that the active learning model achieves satisfactory accuracy with minimal user input. Our results indicate that our model reduces the user input, i.e., the labeled data, by up to 99% while achieving between 62 and 80% of the prediction accuracy compared to the benchmark with 100% labeled training data. The active learning model is expected to serve as a foundation for expanding NILM adoption in industrial applications by addressing key market barriers, notably reducing implementation costs through minimized worker-intensive data labeling.

In the optimization model, the study considers charging load calculation, site selection, and capacity determination. To deal with the optimization model, the particle swarm optimization is adopted and improved in three aspects. These three improvements include randomly updating inertia weights, introducing acceleration factors to replace learning factors, and introducing fast non-dominated sorting for better or worse selection, and improving the optimization ability of the algorithm by solving the crowding distance. The results showed that the maximum function values of the designed algorithm were 3.56 × 10^–14, 5.32 × 10⁰, and 1.08 × 10¹ for unimodal, multimodal, and composite functions, respectively, and the standard deviations of the algorithm were 2.01 × 10^–14, 3.557 × 10⁰, and 8.56 × 10^–1, all of which were smaller than comparison algorithms.
