Abstract: Contemporary power distribution faces various new challenges.
Most of those challenges have a strong impact on the ICT-structure re-
quired and on system architecture. This contribution briefly introduces
changes and requirements imposed, both for trading and distribution of
power. On this basis, alternatives for ICT architectures are discussed, rec-
ommendations are made on implementation choices for a meaningful sus-
tainable solution, and communication and security challenges are ad-
dressed.
