Abstract

Increasing demand in energy consumption, missed modernisations, and the increasing difficulties in predicting power production due to volatile renewable energy sources (e.g., based on wind or sun) impose major challenges to the power grid. Power supply and power demand are closely interconnected with the need to maintain the power grid in a stable state with a sufficient quality of power. This requires energy-relevant information to be exchanged through the so called Energy Information Network. Communication, however, is challenging within the Energy Information Network due to privacy, security, resiliency, and quality-of-service requirements. Particularly, the resilience of communication within the Energy Information Network needs to be considered to maintain the power grid in a stable and controlled state. This paper suggests a Virtualised Energy Information Network (VEIN), where the Energy Information Network is divided into multiple virtual networks that run over a common substrate network. Furthermore, this paper discusses benefits of this approach in terms of privacy, security, and resilience and points out open research questions.

Virtualisiertes Energieinformationsnetz: Betrachtung der Widerstandsfähigkeit

Zusammenfassung

Steigender Energieverbrauch, nicht durchgeführte Modernisierungen und steigende Komplexität in der Vorhersage der Produktion von erneuerbaren Energien (durch Sonne oder Wind) stellen große Herausforderungen für das Stromnetz dar. Energienachfrage und Energieversorgung sind stark verbunden mit der Notwendigkeit, das Stromnetz in einem stabilen Zustand mit hoher Stromqualität zu halten. Um das zu erreichen, müssen energiebezogene Informationen im so genannten Energieinformationsnetz ausgetauscht werden. Die Kommunikation im Energieinformationsnetz ist allerdings großen Herausforderungen unterworfen, wie etwa Anforderungen an Privatheit, Sicherheit, Widerstandsfähigkeit und Dienstgüte. Speziell die Widerstandsfähigkeit des Energieinformationsnetzes muss gewährleistet sein, um das Stromnetz in einem stabilen und kontrollierten Zustand zu halten. Dieser Beitrag schlägt ein Virtualisiertes EnergieInformationsNetz (VEIN) vor, in dem das Energieinformationsnetz in mehrere virtuelle Netze geteilt wird, die über ein gemeinsames Substratnetz laufen. Die Vorteile dieses Ansatzes werden in Bezug auf Privatheit, Sicherheit und Widerstandsfähigkeit diskutiert, und offene Forschungsfragen werden aufgezeigt.
