Advanced Power Electronic Conversion and Voltage Control Processes for Flexible Grid Operation

Dear Colleagues,

Against the backdrop of the global transition toward low-carbon and clean energy, the large-scale integration of high-penetration renewable energy and power electronic equipment is profoundly reshaping the physical characteristics and operational mechanisms of traditional power grids. Power grids are increasingly evolving toward high-penetration, power electronics-dominated, flexible systems, making efficient energy conversion and active grid-support control technologies increasingly crucial in modern power systems. Nevertheless, the transition from traditional grids to modern power systems with high renewable penetration introduces significant technical challenges in dynamic stability, multi-scale voltage regulation, and high-frequency power conversion.

This Special Issue will gather the latest theoretical developments, technological breakthroughs, and engineering practices in advanced power electronic conversion topologies, grid-forming (GFM) and grid-following (GFL) control strategies, weak grid modeling and stability analysis, refined voltage control under high renewable penetration, and key technologies for enhancing flexible grid operations. Through this Special Issue, we will establish a professional platform for academia and industry to collaboratively address the challenges associated with high-penetration renewable energy grids.

Scope of Interest:

(1). Advanced Power Conversion Topologies and Designs: High-efficiency, high-power-density converter topologies and wide-bandgap semiconductor device applications for renewable energy generation and large-capacity energy storage systems.

(2). Flexible Grid Operation and Control Strategies: Innovative control methods for grid-forming (GFM) and grid-following (GFL) inverters, multi-machine cooperative control, and grid synchronization techniques.

(3). Advanced Voltage Control and Reactive Power Compensation: Dynamic reactive power/voltage control (dynamic VAR), harmonic suppression, power quality cooperative control, and reactive power compensation techniques.

(4). Weak Grid Stability Analysis and Modeling: Impedance modeling of converter-grid interfaces, small-signal/transient stability analysis, wideband oscillation, and interaction mechanism studies.

(5). Smart Operation and Energy Management: Data-driven or AI-based real-time voltage optimization, distributed energy management, and coordinated control in complex distribution networks.

(6). Reliability, Protection, and Fault Ride-Through: Condition monitoring of converter-interfaced systems, fault ride-through (FRT) capabilities, and robust protection schemes.

We invite scholars, researchers, and engineers in related fields to submit their research to this Special Issue. We accept original research articles, state-of-the-art reviews, and typical case studies, aiming to foster discussion and advance technologies in advanced power electronic conversion and flexible grid operations. We look forward to receiving your valuable contributions and insights.
