Special Issue Information

Dear Colleagues,

The global energy transition, driven by large-scale renewable integration, modernized grid infrastructure, and the electrification of transportation, is placing increasing demands on grid-tied power converters for higher efficiency, greater reliability, and improved grid-forming and grid-following capabilities under diverse operating conditions.

This Special Issue, “Advances in Modulation, Control and Applications of Grid-Connected Power Converters”, aims to bring together cutting-edge research on advanced modulation methods, intelligent control strategies, and innovative applications that push the boundaries of performance, efficiency, and reliability in next generation power electronics conversion systems.

The collection emphasizes cross-cutting innovations spanning renewable integration, grid-integrated energy storage systems, solid-state transformers, electric vehicle charging infrastructures, industrial automation, flexible AC transmission systems (FACTS), high-voltage direct current (HVDC) technologies, and other emerging grid solutions.

We welcome contributions covering, but not limited to, the following: novel modulation methods and advanced control techniques for reliability enhancement, stability and transient performance improvement, harmonic suppression, efficiency enhancement, optimal switching pattern design, battery and capacitor lifetime management, and fault ride-through capability enhancement. Advancements in system integration architectures and real-world hardware implementations, as well as the integration of wide-bandgap devices and their associated control challenges, are also encouraged.

By bridging the gap between academic research and industrial deployment, this Special Issue will serve as a platform for researchers, engineers, and industry professionals to exchange insights, share innovative ideas, and explore emerging trends shaping the future of grid-connected power conversion systems.

We warmly invite original research papers, reviews, and case studies from academia, research institutes, and industry.

The Modular Multilevel Matrix Converter (M3C) has the potential to contribute to onshore grid frequency response by utilizing the electrostatic energy stored in its submodules. However, in the current offshore wind power domain, control schemes for M3C-based Low-Frequency AC transmission systems (M3C-LFACs) fail to effectively exploit the capacitor energy of M3C to provide adequate inertia support. Existing M3C controls are typically grid-following and thus suffer from stability issues under weak-grid conditions. To address this challenge, a dual-port grid-forming control strategy for M3C-LFAC systems is proposed, based on an energy synchronization loop. This approach enables phase-locked-loop-free synchronization between the M3C and the grid while establishing low-frequency link voltage vectors. Building on this foundation, an optimized energy utilization method for M3C total energy is introduced, featuring a two-stage preset curve to maximize the system’s inherent energy for frequency response. Under varying levels of grid load disturbances, the proposed scheme ensures that M3C-LFAC systems can provide optimal inertia support. Finally, simulation studies in MATLAB 2024b/Simulink validate the effectiveness and advantages of the proposed method. Full article
