Title (EN) SYSTEM AND METHOD FOR DISTRIBUTED GRID CONTROL WITH SUB-CYCLIC LOCAL RESPONSE CAPABILITY
(FR) SYSTÈME ET PROCÉDÉ DE COMMANDE RÉPARTIE DE RÉSEAU AVEC CAPACITÉ DE RÉPONSE LOCALE SOUS-CYCLIQUE
Abstract:
(EN) Distributed static synchronous series compensators (DSSSCs) which may also be designated tower routers capable of injecting series inductive or capacitive impedances to enable distributed power-flow control. When a large number of these (a fleet of) DSSSCs are distributed over the grid for power-flow control, it is necessary to ensure that coordinated communication and control capabilities are also established, enabling fast reaction to changes that can exist across the grid. A system architecture and method for enabling localized high-speed low-latency intelligent control with communications between subsections (local network) of the grid along with communication to the central Grid operations center at the utility for supervisory control is disclosed herein. The architecture provides sub-cyclic (<1/60 of a second) response capability, using the local DSSSCs with high-speed communication at the local network level to power-system disturbances, such as power-oscillation damping (POD), sub-synchronous resonance (SSR) etc.
(FR) L'invention fait intervenir des compensateurs série synchrones statiques répartis (DSSSC) qui peuvent également être des routeurs de pylônes désignés capables d'injecter des impédances inductives ou capacitives en série pour permettre une commande répartie du transit de puissance. Lorsqu'un grand nombre (un parc) de ces DSSSC est réparti sur le réseau pour la commande du transit de puissance, il est nécessaire de s'assurer que des capacités coordonnées de communication et de commande sont également établies, permettant une réaction rapide à des changements pouvant exister à travers le réseau. Une architecture de système et un procédé destinés à permettre une commande intelligente localisée à grande vitesse et faible latence, avec des communications entre sous-sections (réseau local) du réseau ainsi qu'une communication vers le centre d'exploitation centralisée du réseau au niveau de la compagnie d'utilité publique en vue d'une régulation de supervision, sont décrits ici. L'architecture apporte une capacité de réponse sous-cyclique (<1/60 de seconde), à l'aide des DSSSC locaux avec communication à grande vitesse au niveau du réseau local, à des perturbations du système de puissance, comme l'amortissement d'oscillations de puissance (POD), la résonance sous-synchrone (SSR), etc.
