   Multilevel Modular Converter Design and optimization
By Colin OATES [View]
[Download]

Abstract: The Multilevel Modular Converter (MMC) originally proposed by Rainer Marquardt has made itpractical to realise converters with ratings of up to 1000MW using standard industrial components.The use of many “submodules”, in which all the power electronics is contained, to realise a converterwhere the AC and the DC voltages are under direct control and have very little noise content appearsto be an ideal; however for these converters to operate against all the variations that might be expectedin service requires careful consideration of the number of submodules that will be required. Thepresentation will give a general description of the converters being constructed for the “South West”HVDC link in Sweden and will then develop the mathematical description of the convertersoperation. From this it will be demonstrated how these variations are accounted for in the converterdesign.

   Power Electronics for Energy efficiency and Smart grid : Innovations and perspective
By Miao-Xin WANG [View]
[Download]

Abstract: The world is facing huge energy challenges : increasing energy demand and necessity to reduce CO2emission. Power Electronics should play a key role to address these callenges.In order to continue to improve energy efficency of power converters. we must accelerate adoption ofadvanced power semiconductors (SiC, GaN),and development of new topologies and control.Power Electronics can play important roles to solve issues due to intermittence power generation ofrenewables : grid stability, and voltage variation,Starting from current Schneider Electric's offer using Power Electronics, the presentation gives apanorama of our innovation actions and perspective for Energy efficiency and Smart grid.

   R&D opportunities for Supergrid issues : technological propects
By Philippe EGROT [View]
[Download]

Abstract: Prospects of natural resources exhaustion and environmental issues, particularly climaticmodifications, provide a wide focus for research. Europe which has got few fossil resources in its soilneeds to increase energy efficiency of electricity uses and integrate massive renewable generation,more than 20\% by 2020.As a consequence, many “Supergrids” projects appeared during last years, more or less realistic. Mostof these studies highlighted several technological barriers:• How to break a DC current greater than 10kA_• How to reduce losses due to AC/DC converters and build reliable meshed DC grids_• How to reduce investment costs for long HVDC links_• How to improve off-shore behavior for submarine equipment_All these questions are highly interesting research subjects, especially for power electronics scientists.
