1 Innovative Concepts for Efficient Electrical Distribution Grids Torsten Hammerschmidt, Project Manager RWE Deutschland AG Essen, Germany

2 Frankfurt (Germany), 6-9 June 2011 Torsten Hammerschmidt, RWE Deutschland – Germany – Session 5 – Paper 0447 The Project: Grids for Future Electricity Suppy Project Consortium Project LeaderRWE Deutschland AG TimelineJuly 2009 – June 2011 Identification of Efficient Distribution Grid Concepts Further Development of Evaluation Methods Further Development of Equipment Realisation of a Demonstration Grid Objective

3 Frankfurt (Germany), 6-9 June 2011 Torsten Hammerschmidt, RWE Deutschland – Germany – Session 5 – Paper 0447 Photovoltaics will Exceed Growth Rates of Wind Power in Germany Demonstration Grid Area: 130 km²Covered Area 4,100Inhabitants 1,900Service Connections 6.0 MWRen. Generation 2.5 MWMax. Load Source: BMU Pilot Study (Dec 2010)

4 Frankfurt (Germany), 6-9 June 2011 Torsten Hammerschmidt, RWE Deutschland – Germany – Session 5 – Paper 0447 Smart Grid Demonstration in a Rural German Area Use of Information- and Communication Technology (ICT) Disposition of Storage Devices Local Voltage Control to exploit Grid Transportation Capacity Hierachical Supply Layers in Medium Voltage Level -Reconstitution of Grid Observability under high Ren. Generation -Wide Area Control -Biogas Storage in Coordination with PV Generation works as a Virtual Electricity Storage -Inside Medium Voltage Grid, at Substations and Service Connections -Strong Cable Line with Electronic Sectionalizers

5 Frankfurt (Germany), 6-9 June 2011 Torsten Hammerschmidt, RWE Deutschland – Germany – Session 5 – Paper 0447 Local Voltage Control to exploit Grid Capacity m Grid Load S=8 MVA P=7.2 MW Q=3.5 Mvar cosφ=0.9 AC / DC /AC P=7.4 MW Q=3.2 Mvar P=0.7 MW Q=0.3 Mvar P=6.5 MW Q=3.2 Mvar P=0.9 MW Q=0.0 Mvar ΔU = 20% S Voltage-Regulation =0.8 MVA (approx. 10% throughput load)

6 Frankfurt (Germany), 6-9 June 2011 Torsten Hammerschmidt, RWE Deutschland – Germany – Session 5 – Paper 0447 Medium Voltage 3 ~ Fermenter Biogas Storage 3 ~ Source: Ceno Tec 3.0 MWh el PV AC DC Biogas Storage in Coordination with Photovoltaics Generation works as a Virtual Electricity Storage

7 Frankfurt (Germany), 6-9 June 2011 Torsten Hammerschmidt, RWE Deutschland – Germany – Session 5 – Paper 0447 Thank you for your Attention Photovoltaics Windpower Biogas Generation Authors: Torsten Hammerschmidt, RWE Deutschland, Essen Dr. Thorsten Borchard, ABB, Mannheim Dr. Jörg Feldmann, Consentec, Aachen Dr. Astrid Petermann, RWE Rhein-Ruhr Netzservice GmbH, Siegen Prof. Dr. Christian Rehtanz, TU Dortmund Biogas Storage (Under Construction)
