The Application of Power Electronics Technology in Power and Energy Systems

Dear Colleagues,

The accelerating global energy transition is driving the emergence of highly electrified and digitally integrated power infrastructures, fundamentally reshaping power and energy systems worldwide. In this evolving landscape, power electronics has become a pivotal enabling technology, forming the essential interface between renewable generation, modern grids, electrified transportation, industrial processes, and advanced energy storage solutions. As energy systems move toward architectures dominated by converter-based resources, new opportunities for efficiency, controllability, and flexibility emerge, together with multifaceted technical challenges spanning device physics, converter design, dynamic stability, and system-level coordination.

The rapid advances in semiconductor devices, converter architectures, control strategies, and system-integration methodologies are making power electronic systems more efficient, compact, and intelligent, while also elevating expectations for operational stability, resilience, and reliability. At the same time, the growing penetration of converter-based resources in power networks has introduced new technical challenges, including multi-timescale dynamic interactions, weak-grid instability, and the need for sophisticated modelling, protection, and coordination strategies across system layers.

 This Special Issue aims to present and disseminate the latest advances in device technologies, converter designs, modelling and control methods, system-level analysis, and emerging applications that shape the future of power-electronics-based energy systems.

Topics of interest for publication include, but are not limited to, the following:

• All aspects of energy conversion and management for renewable, storage, hydrogen, industrial, transportation, and other electrification systems, etc.
• Converter technologies for renewable energy integration, including utility-scale PV and onshore/offshore wind, etc.
• AC, DC, and hybrid AC/DC microgrids for distributed and high-renewable-penetration applications, etc.
• Solid-state transformer (SST)-enabled architectures and multi-terminal power-electronics-based grids, etc.
• Vehicle-to-Grid (V2G) and Vehicle-to-Everything (V2X) interfaces and their roles in grid flexibility and ancillary services, etc.
• Power conversion and control for energy storage systems, including BESS, supercapacitors, flywheels, hybrid storage, etc.
• Power electronics for Power-to-X (PtX) pathways, including electrolyzers, fuel cells, and multi-energy coupling, etc.
• Converter technologies for data centers, high-performance computing, and electricity-intensive infrastructures, etc.
• Industrial electrification and flexibility, including power electronics for drives, robotics, adaptive industrial loads, etc.
• Converter interaction mechanisms, multi-timescale dynamics, and advanced modelling of PE-dominated systems, etc.
• Grid-support functionalities and resilience enhancement provided by power electronic converters, etc.
• Fault ride-through, system recovery, and black-start capabilities enabled by advanced converter technologies, etc.
• AI- and data-driven methods for design automation, adaptive control, monitoring, predictive diagnostics, etc.
• Coordinated control, optimization, and energy management of multi-energy and multi-converter systems, etc.
