A vision of future energy networks

Distributed generation as well as a growing share in stochastic energy sources will lead to deep changes in electricity transmission & distribution (T&D). In the vision of future energy networks project, these changes are investigated by means of a greenfield study. New concepts and analysis methods shall be used to design an optimal energy system regardless of its actual structure. This paper introduces the key elements of an envisioned multi carrier energy system: energy hubs interfacing any type of consumer or producer, managing and storing energy, and energy interconnectors transferring energy in several forms between the hubs. The resulting scenarios and new technologies will serve in strategic planning of research and development (R&D) and network expansion
