Session I: Operation strategies for distribution networks with high share of renewables

In this session, German and international DSOs share their experience with the integration of high share of renewables into distribution networks and outline future developments/solution.
14:15 - 15:35 Presentations (25 minutes each):
  • On the last miles to 100% Renewables – experiences and solutions of a large DSO in Northern Germany
    Speaker: Enno Wieben (EWE, Germany)
  • Upside-down distribution. Feeding the transmission network: the experience of Enel Distribuzione
    Speakers: Riccardo Lama (Enel Distribuzione, Italy), Helge Urdal (National Grid, UK)
  • Future challenges in the ewz distribution grid and current innovation projects
    Speaker: Raffael La Fauci (EWZ, Switzerland)
15:35 - 16:00 Discussion
Session Chair: Eckard Quitmann (Enercon, Germany)
16:00 - 16:30 Coffee Break
16:30 - 18:15

Session II: Interface between distribution and transmission network: What is needed from both sides!

With increasing penetration levels of distributed renewables, operation of transmission and distribution networks must be coordinated much better in the future than they are today. In this session, TSO/DSOs report on their current ideas.
16:30 - 17:50 Presentations (25 minutes each):
  • Conceptual design of the future intelligent Danish power system
    Speaker: Per Lund (, Denmark)
  • Interface TSO-DSO: Reactive power and defence plan
    Speaker: Hans Abele (TransnetBW, Germany)
  • Voltage control with high penetrations of distributed renewable generation – a TSO perspective
    Speaker: Simon Tweed (Eirgrid, Ireland)
17:50 - 18:15 Discussion
Session Chair: Helge Urdal (National Grid, UK)
19:00 - 22:00 Conference Dinner
Day 2: 20 June 2013 - Thursday
08:00 - 09:50

Session III: Principle solutions to high penetration challenges

Distributed renewable energy sources mainly influence voltage levels in distribution networks. In this session, the issue of voltage control with distributed renewable generation is discussed from different points of view.
08:00 - 09:20 Presentations (25 minutes each):
  • Voltage Regulation overview - examples from R&D projects
    Speaker: Adam Slupinski (ABB, Germany)
  • Improved voltage quality and voltage stability using continuous voltage control
    Speaker: Markus Pöller (M.P.E., Germany)
  • Grid integration of distributed PV-generation
    Speaker: Bernhard Ernst (SMA Solar Technology AG, Germany)
09:20 - 09:50 Discussion
