4. Main GREDOR aims
Study investment planning, operational planning and real-time control
strategies from a functional perspective - what do we want to aid? - from
a computational perspective - how do we optimise the decisions? - and
from an organisational perspective - how do system actors interact?
We build IT tools to do so. These tools plugged into a simulation
framework provide quantified recommendations for system evolution.

Available controls: •reconfiguration •flexibility contracts •storage •regulation devices
Goals: •take preventive actions to have the system in a
secure state in real time, •with sufficient controls to maintain it there in RT • Trade off preventive versus corrective actions.

ANM Benchmark.
In order to promote the development of computational techniques
for Active Network Management (ANM), we propose a test
instance of a generic ANM problem. It can be used as a test bed for
comparing existing computational techniques, as well as for
developing new ones.
