Avec l'augmentation progressive de l'application de nouvelles énergies dans les micro-réseaux, le ressort électrique (ES), en tant que nouveau type de dispositif électronique de puissance de compensation distribuée, a été largement étudié. Le ressort électrique généralisé (G-ES) est une topologie améliorée, et le problème de limitation d'espace dans la topologie traditionnelle est résolu. En raison du mode d'utilisation du G-ES dans le réseau électrique, une solution raisonnable à la perte de tension du départ de la section critique est nécessaire. Dans cet article, l'équation d'équilibre de tension basée sur le coefficient de compensation anticipée est établie et une stratégie de contrôle à deux cascades basée sur l'équation est étudiée. La première étape de la stratégie de contrôle à deux cascades consiste à utiliser des moyens de communication pour réaliser l'attribution de coefficients de compensation anticipative, et la deuxième étape consiste à utiliser les coefficients pour réaliser une commande d'angle fixe anticipative. L'analyse de simulation montre que la stratégie de contrôle proposée n'affecte pas la précision du contrôle de la charge critique (CL) et améliore efficacement la plage opérationnelle du G-ES.

Abstract: With the gradually increase of the application of new energy in microgrids, Electric Spring (ES), as a new type of distributed compensation power electronic device has been widely studied. The Generalized Electric Spring (G-ES) is an improved topology, and the space limitation problem in the traditional topology is solved. Because of the mode of G-ES use in the power grid, a reasonable solution to the voltage loss of the critical section feeder is needed. In this paper, the voltage balance equation based on the feedforward compensation coefficient is established, and a two cascade control strategy based on the equation is studied. The first stage of the two cascade control strategy is to use communication means to realize the allocation of feedforward compensation coefficients, and the second stage is to use the coefficients to realize feedforward fixed angle control. Simulation analysis shows that the proposed control strategy does not affect the control accuracy of the critical load (CL), and effectively improves the operational range of the G-ES.
