Control de aerogeneradores "Grid-Forming"

, 2021
[CA] En el següent projecte es planteja el disseny d’un llaç de control amb que realitzar la connexió de dos aerogeneradors a la xarxa elèctrica. Aquest control està basat en tècniques Grid-Forming i control vectorial. Per a això, es planteja un model analític que representa la dinàmica elèctrica de la connexió a la xarxa a partir d’un llaç de tensió ...

Dynamic Complex-Frequency Control of Grid-Forming Converters

IECON 2024 - 50th Annual Conference of the IEEE Industrial Electronics Society
Complex droop control, alternatively known as dispatchable virtual oscillator control (dVOC), stands out for its unique capabilities in synchronization and voltage stabilization among existing control strategies for grid-forming converters. Complex droop control leverages the novel concept of ``complex frequency'', thereby establishing a coupled ...

Operation of a Grid-Forming Converter Controlled by the Flux Vector

IEEE Access
The electric power system is undergoing a significant transition. Renewable energy generation capacity has increased, leading to the displacement of synchronous generators (SG) and a growing concern about grid stability due to the decrease of rotating inertial energy. Grid-forming (GFM) converters have become a technological solution to this challenge,
