Title
(EN) COMPOSABLE METHOD FOR EXPLICIT POWER FLOW CONTROL IN ELECTRICAL GRIDS
(FR) PROCÉDÉ POUVANT ÊTRE COMPOSÉ POUR UNE COMMANDE DE FLUX DE PUISSANCE EXPLICITE DANS DES RÉSEAUX ÉLECTRIQUES
Abstract
(EN)
A power flow control system for an interconnected power system, the interconnected power system comprising a plurality of electrical subsystems; an abstract framework configured to work as a utility maximiser under constraints (that applies to the electrical subsystems by specifying their capabilities, expected behavior and a simplified view of their internal state);and a plurality of agents. Each agent is responsible of one or a plurality of the electrical subsystems, comprises means configured to express an internal state of the electrical subsystem within a common system of coordinates, and has communication means configured to communicate among agents according to a protocol. The abstract framework means enables a composition of a set of the interconnected electrical subsystems into a further subsystem for which a further internal state is expressed within the same common system of coordinates used before, the further internal state being communicated with other agents according to the protocol.
(FR)
L'invention porte sur un système de commande de flux de puissance pour un système de puissance interconnecté, le système de puissance interconnecté comprenant une pluralité de sous-systèmes électriques; une infrastructure abstraite configurée pour travailler comme un agent de maximisation de l'utilité sous contraintes (qui s'appliquent aux sous-systèmes électriques par spécification de leurs capacités, comportement attendu et une vue simplifiée de leur état interne); et une pluralité d'agents. Chaque agent est responsable d'un ou d'une pluralité des sous-systèmes électriques, comprend des moyens configurés pour exprimer un état interne du sous-système électrique au sein d'un système commun de coordonnées, et possède des moyens de communication configurés pour communiquer entre agents selon un protocole. Le moyen d'infrastructure abstraite permet une composition d'un ensemble des sous-systèmes électriques interconnectés en un sous-système supplémentaire pour lequel un état interne supplémentaire est exprimé au sein du même système commun de coordonnées utilisé précédemment, l'état interne supplémentaire étant communiqué à d'autres agents selon le protocole.
