Abstract

Lors de l'échange ou transmission et distribution d'une puissance par une technologie en utilisant chaque dispositif d'interconnexion non synchrone à bornes multiples décrit dans un document de brevet (1), il est nécessaire de déterminer une route d'échange et la quantité de puissance à échanger à travers un convertisseur de puissance à auto-excitation. Selon l'état antérieur de la technique susmentionné, cependant, une règle dans laquelle la perte de transmission de puissance pour la route d'échange est rendue minimale est seulement décrite. Dans le futur, étant donné que des procédés pour échanger et transmettre et distribuer diverses formes de puissance ou une puissance en utilisant divers dispositifs de transmission et de distribution de puissance et des dispositifs de distribution de puissance sont espérés, un procédé pour déterminer une route d'échange de puissance en utilisant un indice représentant l'effet d'échange et de transmission et de distribution de puissance spécifique autre que la perte de transmission de puissance et un dispositif mettant en œuvre le procédé sont requis. Comme il est indiqué dans la partie ci-dessus du problème à résoudre par l'invention, tout d'abord la présente invention utilise, en tant que données d'entrée, des informations de connexion et une base de données d'installation dans un réseau utilisé lors d'un échange de puissance et des caractéristiques non décrites dans le document de brevet et représentant le rendement de conversion du convertisseur de puissance à auto-excitation dans le dispositif d'interconnexion non synchrone à bornes multiples pour calculer une route d'échange à travers laquelle un grand nombre de convertisseurs de puissance à auto-excitation dans les dispositifs d'interconnexion non synchrones à bornes multiples installés dans le réseau cible entier fonctionnent au rendement maximal (perte de convertisseur de puissance à auto-excitation minimale) globalement. De plus, la dépense pour un échange de puissance se produisant durant l'échange est également calculée simultanément. De plus, en plus de rendre minimale la perte de convertisseur de puissance à auto-excitation, un flux de puissance est distribué de manière optimale de telle sorte qu'un indice d'énergie verte est rendu maximal, lequel devient un indice représentant la quantité d'utilisation de puissance dérivée depuis une énergie renouvelable, et un plan d'échange pour rendre maximale l'utilisation de puissance dérivée depuis une énergie renouvelable et un procédé de commande sont conçus.
