High-Power Electronics for Decarbonizing Energy Grids

The worldwide shift towards electrification and digitalization mandates the adoption of energy-efficient and economically viable methods for electricity generation, transmission, and utilization. Meeting this demand requires the integration of power electronics and digital technologies, which are critical to address these challenges. Recently, modern energy grids are increasingly incorporating high-power, high-/medium-voltage power electronic converters and systems, e.g., high-voltage direct-current (HVDC), static synchronous compensators (STATCOMs), large-scale renewable power plants and power-to-x stations, hyperscale data centers, solid-state circuit breakers, solid-state transformers, and grid-forming energy storage systems, etc.

The objective of this workshop is to provide a forum where speakers from government, industry and academia can share and discuss the latest developments in high-power electronics and digital technologies for future net-zero energy systems. With a strong industry focus, the event is co-sponsored by IEEE Power Electronics Society (PELS) and Digital Futures, and co-organized by KTH Royal Institute of Technology and Hitachi Energy. The programme features three topic areas: 1) high-power electronic devices and converters, 2) system integration and operation, 3) grid stability, security, and digitalization.
