[1] Virtual Power-Based Technique for Enhancing the Large Voltage Disturbance Stability of HV Grid-Forming Converters 2023 25th European Conference on Power Electronics and Applications (EPE'23 ECCE Europe), 09/2023, URL, Abstract LABA Yorgo, BRUYERE Antoine, COLAS Frédéric, GUILLAUD Xavier |
Grid-forming control plays an essential role in the modernization of HV electrical transmission grids, particularly in mitigating challenges imposed by large voltage disturbances. In this context, the concept of virtual power has gained prominence as a potential approach that improves stability following such disturbances. This paper illustrates the use of virtual power method in enhancing the large disturbance stability given by the grid-forming control. An adaptive virtual impedance is also proposed to further improve system dynamics. The methods are evaluated through large disturbance stability analysis and time-domain simulations. |
[2] PQ Decoupling on Grid-Forming Converter Connected to a Distribution Network 2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 06/2022, URL, Abstract LABA Yorgo, BRUYERE Antoine, COLAS Frédéric, GUILLAUD Xavier |
In recent years, several works on grid-forming converters in transmission networks have been performed. Since these high voltage grids are mainly inductive, a natural decoupling exists between active and reactive power controls. This decoupling facilitates the design and the performance of the grid-forming controllers. However, in distribution applications, it is well known that the R/X ratio of the line impedance is substantially higher, preventing the system from a natural decoupling effect. This paper proposes an original solution to decouple the control and gives an application to a low voltage connection of a grid-forming converter. |
[3] Operating Grid-Forming Control on Automotive Reversible Battery Charger 2021 IEEE Vehicle Power and Propulsion Conference (VPPC), pages. 6, 10/2021, URL, Abstract LABA Yorgo, BRUYERE Antoine, COLAS Frédéric, GUILLAUD Xavier |
Nowadays, the production of electric energy is evolving towards decentralized systems by an increasingly advanced integration of new active loads such as electric vehicles and renewable energy sources. This energy transition involves the use of power electronics converters to regulate energy exchanges. In this context, this paper brings the L2EP knowledge on grid-forming control developed in a high-voltage context to the ValeoSiemens reversible charger. This comprises two significant differences in the sizing of the system: a lower grid connection impedance and a resistive aspect of the distribution network. To overcome these challenges, this paper proposes two techniques: the virtual impedance to compensate the low value of connection impedance and dynamic decoupling of active and reactive power to consider the resistive effect of the distribution network. |
