Abstract
(EN)
There is provided methods and apparatus configured to provide electrical converter control parameters, the apparatus comprising: a Structured H-infinity tuning module configured to determine one or more control parameters, for a model of an electrical converter control system and grid, based on variation of one or more grid parameters; and an output module configured to provide the one or more control parameters for implementation in the electrical converter control system.
(FR)
L'invention concerne des procédés et un appareil conçus pour fournir des paramètres de commande de convertisseur électrique, l'appareil comprenant : un module d'accord à H-infini structuré, configuré pour déterminer un ou plusieurs paramètres de commande, pour un modèle d'un système et d'un réseau de commande de convertisseur électrique, sur la base d'une variation d'un ou de plusieurs paramètres de réseau ; et un module de sortie configuré pour fournir le ou les paramètres de commande pour une mise en œuvre dans le système de commande de convertisseur électrique.
