Special Issue Information
Dear Colleagues,
As a result of the continuous development of power systems, the scale and complexity of AC/DC grids have been growing steadily. With the increasing integration of high-proportion renewable energy sources, the system inertia and short-circuit current ratios are being weakened. The fault modes in power systems, whether symmetrical or asymmetrical, are becoming increasingly complex and variable. Current-limiting technology can effectively reduce short-circuit currents, thereby protecting critical equipment in the grid and extending its service life. As power electronics technology advances, novel current-limiting technologies are emerging. By synergizing with other devices, these technologies enable the rapid protective actions and effective isolation of faults. Based on actual grid operational conditions, the dynamic adjustment of current-limiting strategies optimizes resource allocation. Exploring the principles of new current-limiting technologies further enhances their intelligent level and adaptability, enabling them to meet evolving grid demands. Strengthening the integration of current-limiting technologies with other grid technologies achieves overall grid optimization and coordinated operation. This provides more effective solutions to ensure secure and stable grid operation, while promoting the application and development of novel current-limiting technologies across industries.
This Special Issue of Symmetry seeks to show the significance of expressing new ideas and conducting research. The topics of interest for this Special Issue include, but are not limited to, the following areas:
- Solid-state fault current limiters (SSFCLs) for AC/DC grids;
- Superconducting fault current limiters (SFCLs) in modern grids;
- DC grid fault protection and current limiting techniques;
- AI and machine learning for fault current prediction and mitigation;
- Hybrid current-limiting solutions for renewable-integrated grids;
- Advanced materials and devices for current-limiting applications;
- Economic and reliability analysis of FCL deployment in power systems.
