   A Novel Grid-demanded Power Point Tracking (GPPT) Control Method for Wind Turbines to Preserve Grid Stability with High Wind Energy Penetration
By David MATTHIES [View]
[Download]

Abstract: To keep a stable grid operation despite shut-down power plants, wind turbines need to provide equal ancillary services. Therefore, a sophisticated grid-demanded power point tracking (GPPT) control method is proposed. This control strategy was successfully validated on a test bench, so that it may probably run on real wind turbines.

   Control Principles for Black Start and Island Operation of Offshore Wind Farms integrating Grid-Forming Converters
By Daniela PAGNANI [View]
[Download]

Abstract: In this paper, control principles to perform black start services by offshore wind farms (OWFs)integrating grid-forming (GFM) control are presented. The strategy consists in exploiting a GFM batteryenergy storage system (BESS) to provide black start services by an OWF equipped by grid-followingwind turbines. Controller modelling and operation methodology are explained. In order to show theproposed control and operation principles, the analysis is implemented on the CIGRE Working GroupC4.49 benchmark, which could resemble modern large OWFs in the United Kingdom, such as HornseaProject 1 and 2. Analysis simulations in the software PSCAD show the success of the proposed strategy.

   Field-measurement based hygrothermal modelling of the converter-cabinet climate in wind turbines
By Katharina FISCHER [View]
[Download]

Abstract: Power converters in wind turbines suffer from frequent failures. Root-cause analyses point to environmental influences as important drivers of converter failure. Based on comprehensive field measurements in wind turbines, we derive hygrothermal models describing the dependence of temperature and humidity in the converter cabinet on the ambient climatic conditions and turbine operation. The results show that lumped-parameters models of minimal complexity are suitable for describing the conditions with reasonable accuracy and that publicly available ERA5 reanalysis data may be used to consider the site-specific climatic conditions outside of the wind turbine. In addition, we demonstrate that the hygrothermal model derived for a turbine type can successfully be transferred to identical turbines operating in other countries. The models can therefore serve as a basis for refined requirement specifications as well as for the derivation of application-specific test procedures for power converters and their components.
