GREDOR - Gestion des Réseaux Electriques de Distribution Ouverts aux Renouvelables

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.

Questions •What to publish, who to?•is base case actual system or with foreseen investment?

Goals:•estimate & communicate capacity of network through a set of indicators•incentivise connections in good locations from network’s perspective•incentivise flexibility service in good locations

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.

Page 1 of 4http://www.montefiore.ulg.ac.be/~anm/

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.
