Tesla World 2015 Ronnie Belmans Keeping the Balance

  1. 1. Keeping the balance Ronnie Belmans CEO of EnergyVille / Professor at University of Leuven Executive Director of Global Smart Grid Federation Honorary Chairman of Elia
  2. 2. The world is changing Europe:
  3. 3. We're the first generation to feel the impact of climate change and the last generation that can do something about it. Barack Obama – August 2015 The world is changing USA: Clean Power Plan
  4. 4. Keeping the balance
  5. 5. Generation Demand Safe System Operation Keeping the balance
  6. 6. Balancing the grid
  7. 7. Balancing the grid
  8. 8. Trends Large-scale integration of Renewable Energy Sources Large-scale integration of Distributed Energy Resources Evolution towards smart grids
  9. 9. Demand drives generation ! Challenges !!! !!! generation drives demand !!! Techno-economical puzzle: coordinated grid actions with all the players involved Bidirectional flows
  10. 10. How to tackle these? “ To adapt … or to adapt ” Hobson’s Choice
  11. 11. Sustainability Affordability Availability Energy Supply Keeping the balance
  12. 12. Flexibility is key – an opportunity! Consumer-side Flexibility Shiftable Demand Generation-side Flexibility Flexible Generation Storage Electricy Heat
  13. 13. Consumer Flexibility: demand response When large amounts of renewable energy are injected, grid overload situations are possible Activation of additional demand can solve thisQuote (Art. 15.8) from the European Commission Energy Efficiency Directive (2012/27/EU): “Member states shall promote access to and participation of Demand Response in balancing, reserves and other system services markets” flexible load
  14. 14. Sources of Consumer Flexibility Residential SME & buildings Large Industry

  16. 16. First electric power system 1882 Pearl Street Station, NY Coal Powered DC GeneratorDesign by Thomas Edison Used for lighting
  17. 17. Demand = street lighting Early Demand Side Management Only at night Electricity Showrooms Public: women Electric Household Appliances
  18. 18. Flexibility is key – an opportunity! Consumer-side Flexibility Shiftable Demand Generation-side Flexibility Flexible Generation Storage Electricy Heat
  19. 19. Generation-side Flexibility Either you start up extra classic power stations (peak plants) But peak plants are hard to keep economically viable You can also look for production elsewhere?
  20. 20. Energy Generation in Europe Demand Renewable Energy Sources International connections are called for
  21. 21. Has the current transmission grid limits? Stretching was a succes with trains Not so with sailing ships So, do we go for an AC grid or a DC grid? Stretching was a succes with trains
  22. 22. +130 years ago…
  23. 23. Which Current?
  24. 24. Thanks to AC: Fast growing economies in US & Europe To satisfy more demand: Large hydro power plants Large thermal power plants Large load centers Interconnected AC Networks: Balance the system better Minimise reserves
  25. 25. Interconnected AC Networks 1900191019201930
  26. 26. Interconnected AC Network How far can we stretch the current AC Grid? 1948195619742008
  27. 27. Flexibility is key – an opportunity! Consumer-side Flexibility Shiftable Demand Generation-side Flexibility Flexible Generation Storage Electricy Heat
  28. 28. Storage technologies Mechanical Chemical Electrical Electrochemical Thermal
  29. 29. Batteries Pro: Scalability Efficiency Energy Density Mass Production Rapidly falling costs of battery packs for electric vehicles Björn Nykvist and Måns Nilsson, Nature Climate Change, 2015
  30. 30. Batteries in Practice Transmission Grid West Mecklenburg, Germany
  31. 31. Batteries in Practice Wind farm optimisation Rokkasho Futamata Wind Farm, Japan Transmission line 51 MW Wind Turbine (1,5MW x 34 Units) 34 MW (245 MWh) NAS Battery
  32. 32. Battery Energy Systems in Practice Community Energy Storage Toronto, Canada
  33. 33. Batteries in Practice SolarCity, Tesla Powerwall At your home? SolarCity, Tesla PowerwallIron Edison
  34. 34. Batteries in Practice In your car! Tesla Motors

  36. 36. Electric Vehicles New? Fritchle Electric 1908 Detroit Electric 1910 General Vehicle Company 1912
  37. 37. Electric Vehicles New? No gears & no cranking Reliable Convenient refueling at home Beneficial for power station operation High market share in US in 1900 (1575 electric vs. 936 gasoline cars)
  38. 38. Electric Vehicles New? 1905-1925: combustion engine took over: 1911 electric starter Abundant oil reserves in USA Ford Model T: 440$ 1925: 4% market share for electric vehicle in USA
  39. 39. Flexibility is key Consumer-side Flexibility Shiftable Demand Generation-side Flexibility Flexible Generation Storage Electricy Heat
  40. 40. Back to the future: Decentralised Supply MICROGRID Flexible Demand Storage Distributed Generation
  41. 41. +130 years ago…
  42. 42. The first grids = microgrids Self-contained & Isolated Systems Low-voltage DC power Battery backup for: peak power Short-term reserve Lead-acid
  43. 43. Why would flexibility work now? We’ve already seen: Demand-side management Decentralised systems Electrical vehicles All devices Communicate With each other Share information Greater efficiency Automation Security Comfort
  44. 44. Smart Grids & Smart Cities End-to-end systems
  45. 45. Electric Vehicles are Helping Environmentally Friendly Positive Price Evolution Smart Devices Flexible Buffer Load Intelligent integration of electric vehicles is key! “First they ignore you, then they laugh at you, then they fight you, then you win.” [Mahatma Gandhi]
  46. 46. Challenges for the Smart Grid Security Privacy Stable Performance Market & Regulation Big Data Keeping the balance
  47. 47. What would Edison think of all this? In discussion with Henri Ford and Harvey Firestone in the 1930’s: “I’d put my money on the sun and solar energy. What a source of power. I hope we don’t have to wait until oil and coal run out before we tackle that.” Keeping the balance… I’d put my money on the sun and solar energy. What a source of power. I hope we don’t have to wait until oil and coal run out before we tackle that.”
