Special Issue Information

Dear Colleagues,

In recent years, with the rapid integration of renewable energy sources, energy storage systems, electric vehicles, and hybrid AC/DC networks, the role of power electronics as the backbone of modern power systems has become increasingly prominent. Power system-driven power electronics not only enable efficient energy conversion but also provide critical functionalities such as grid support, power quality improvement, and system resilience enhancement. To address the emerging challenges in this field, innovations in converter topologies, modulation techniques, and advanced control strategies are essential for achieving higher efficiency, greater power density, enhanced reliability, and cost competitiveness.

This Special Issue seeks to gather cutting-edge research and technological advancements in power electronics driven by power system applications. Topics of interest include, but are not limited to, the following:

  1. Innovative converter topologies (e.g., AC–DC, DC–DC, DC–AC, and multiport converters) for high efficiency, high power density, and low cost, particularly with wide-bandgap semiconductor devices;
  2. Novel modulation and control schemes to ensure high power quality, system robustness, and fast dynamic responses;
  3. Advanced fault diagnosis, fault-tolerant operation, and self-healing control for power converters in grid-connected and standalone systems;
  4. Coordinated control and stability analysis of power electronics in hybrid AC/DC systems, microgrids, and distributed energy resources;
  5. Techniques for soft-start, black start, and hot-swap operations in high-power applications;
  6. Power converter design considering system-level interactions, including grid support and ancillary services.

Garlic is a labor-intensive underground crop in Republic of Korea, where harvesting and collection require substantial manual work. Although self-propelled garlic collectors have been introduced, most were developed empirically, and quantitative evaluations of their load characteristics and power requirements under field conditions remain limited. This study quantifies the power requirements of the driving, collection, and transport parts of a self-propelled garlic collector and examines the effects of driving speed, collecting speed, transporting speed, and working depth. A field measurement system was developed to record torque, rotational speed, flow rate, and pressure, and these data were used to calculate the power requirement of each major component and the overall machine. Results showed that driving speed was the dominant factor affecting total power use, as the driving part displayed a clear increase with higher speeds. In contrast, the collection and transport parts exhibited only minor changes, and the influence of working depth was negligible. The maximum total power requirement was 12.28 kW, about 30% of the rated engine power of 40.2 kW, indicating that engine capacity exceeded actual requirement. These findings provide quantitative insights into self-propelled garlic collectors and essential data for future studies on engine downsizing and power transmission design. Full article

As power electronic converters increase in scale, impedance measurement has become critical for assessing system stability, detecting islanding, and performing other critical analyses. This paper derives the impedance from the voltage and current responses measured after controlled perturbations, employing d-q frame impedance matrices. A static var generator (SVG) with redundant capacity is employed as the perturbation source, and a fractional-order repetitive control (FORC) strategy is introduced to inject the multi-frequency signal efficiently, eliminating the need for additional hardware. By optimizing the perturbation design and suppressing the dynamic error of the phase-locked loop, the method achieves both convergence and accuracy. Comprehensive simulations and experiments validate the approach. Full article
