   Elimination of Back-Electromotive-Force Induced Grid Harmonics in WECS with Multiphase Permanent Magnet Synchronous Generators
By Ioannis TSOUMAS, Lennart HARNEFORS [View]
[Download]

Abstract: This work addresses a harmonic compliance issue of wind energy conversion systems with permanent magnet synchronous generators. The back electromotive force harmonics cause low frequency oscillation of the converter dc-link voltage, which is transferred to the grid in the form of interharmonics. Special current control on the generator side resolves the issue.

   High-Power Rectifier Technologies for Hydrogen Electrolysis
By Zhiyu CAO, Peter WALLMEIER [View]
[Download]

Abstract: In this contribution the development of hydrogen electrolysis and its requirements on power supply are reviewed first. To meet these requirements, virous rectifier technologies and devices are developed: primary power control technology for low-voltage high-current application; 2-stage solution consisting of a thyristor-diode front end and an interleaved IGBT chopper for multi-MW application with a DC output voltage up to 1000 V; unidirectional active front end solution with integrated polarization function for application up to 1500 V. All these technologies are verified by type tests and field application (except technology and product under development).

   Stand-Alone Offshore Wind Energy and Water Electrolysis: A Study on Optimal Electrolyzer Sizing
By Thibaut RUNSER, Sebastian AREND, Rik W. DE DONCKER [View]
[Download]

Abstract: This paper proposes an optimal sizing of a water electrolysis plant connected to a stand-alone wind turbine. Findings suggest that an optimal configuration is achieved by oversizing the plant compared to the wind turbine and that using a modular approach is limited by capital expenditure and efficiency.
