Dutch Power adresses new load typologies 1. The joint application of wind energy at night, existing Distribution Network and public mobility by electrical vehicles is the best contribution to sustainability 2. Dispersed power generation is not always green, central power generation not always grey 3. Innovation is in the process Dutch Power- Binnendijk/ Cobben / Leufkens - NL

Targets of the DP presentation 1. Address planning of network development with regard to new possible load scenario s 2. Stimulate innovation by interactivity 3. Explain what is the society Dutch Power 4. Applying methodology of DP as we are used to
What is Dutch Power? Dutch foundation where utilities meet industries 7 distribution network companies and 26 industries, and 7 consultant companies Platform for joint innovation Four working groups Working group Innovation & Collaboration Speakers: Martin Binnendijk, chairman elect and speaker on Mobile Smart Grids on behalf of Enexis André Postma Paul Leufkens actual chairman Sjef Cobben on dispersed generation
1. Driving on Dutch Power Battery developments Integration of renewable energy Utilization of current grid capacity Mobile Smart Grids
Developments in battery technology Strongly increasing energy and power density and decreasing prices enable e-mobility (at last ) 1 1,000 Energy Density(Wh/lb) 10 100 Power Density(W/kg) 100 High power and/or bipolar lead-acid (1995) Lead-Acid (1967) Ni-Cd Ni-MH SLPB Range:80km 160km 320km 640km 96km/hr USABC Long-term USABC Middle-term 64km/hr 100 10 Power Density(W/lb) 10 32km/hr Li-ion Zn-Br 2 10 100 Energy Density(Wh/kg) Sodium Sulfur 1 1,000
Sustainable mobility within arms reach When charged with renewable electricity, E-mobility enables sustainable transportation
E-mobility supports integration renewables Integration of renewable intermittent generation problematic Charging of electric vehicles offers required flexibility

The Mobile Smart Grid IS NOT: The electric cars The electricity grid The global balancing system for consumption and production The market, pricing and billing systems The hardware, software, and communication parts of the system IT IS: A holistic and integral concept defining the smart grid units and their interfaces which are necessary to facilitate electric transportation and sustainable generation without enormous infrastructure investments!
The Mobile Smart Grid Measure what the connection demand is at one moment Know what the connection needs Know what the net parameters are MV-grid LV-grid Measure what the LV-net demand is at one moment Know what the LV-net needs Know what the net parameters are Measure what the car demands are at one moment Measure what the car needs Know what the car needs Know what the parameters are Steer the demand
