Dutch Power Energy Storage workshop 10 mei 2011

TRANSCRIPT

  • 1. Energy storage for energy consumersMatchen van wensen en mogelijkhedenDutchPower symposium over EnergieopslagFrits Verheij, 10 mei 2011
  • 2. Energy storage for energy consumers1. The balancing act of energy storage2. Applications of energy storage at various levels3. Energy storage enables growing need for flexibility4. Practical examples show value of energy storage 2
  • 3. Focus in the energy market is changing Affordable I II 3
  • 4. but how to keep the triangle in balance?With billions of energy consumers, having different needs which might change during the energy transition phase? 4
  • 5. The balancing act of energy storage Increase of (varying) RES + DG Fuel shift due to electrical vehicles, Ageing assets (grids + power plants) heat pumps, etc. DemandSupply Coupling of electricity, heat (and Increase of luxury resulting in higher cold), and transportation peak loads Increasing dependency on delivery Energy managementPhysical Market Storage facilities (electricity, heat, gas) integrated at home/offices/ Increase of energy trading, e.g. on More need for preventing grid the balancing market overloading, voltage support, Uncertainty of dealing with energy frequency control, PQ storage in a regulated market 5
  • 6. Electricity networks of the future includingenergy storage 6
  • 7. The Electricity Warehouse 7
  • 8. Energy storage for energy consumers1. The balancing act of energy storage2. Applications of energy storage at various levels3. Energy storage enables growing need for flexibility4. Practical examples show value of energy storage 8
  • 9. Energy storages at three levels in theelectric power system Bulk Storage Community Scale Above 50 MW, e.g. 25-100 kW devices sited on the low Pumped Hydro & CAES side of the distribution substationGeneration Utility Scale 250 kW to 2 MW modules with an emphasis on renewables and ancillary services 9
  • 10. Electricity storage system ratings 10
  • 11. Suitability of technologies for singleapplicationsTechnology Pumped D-CAES A-CAES Hydro- NaS Flow Lithium-Ion Lead-Acid Hydro genMaturity ++ + 0 -- + - + ++ Arbitrage Balancing Suitable Pooling Mechanisms needed Black-start e.g. via Smart Energy Flexibility of thermal power plants Application Islanding T&D-Deferral Industrial peak shaving Residential storage Economically Economically Cost Reduction Data Source: Attractive Mid-Term Attractive Necessary BCG and EASE 11
  • 12. Applications at community scale Transportation Plug-in hybrid vehicles All electric vehicles Consumer products Refrigerator / freezer Boilers Power tools Mobile phones 12
  • 13. Energy storage at three levels part 2 Large scale Medium scale Small scale Boiler Heat and cold storage Soil heat exchangeHeat Mass of buildings Geothermal e-storage Thermo-chemical storage Phase change material Electricity Battery CAES Battery Flywheel Pumped hydro Flywheel Super capacitor Gas-fieldGas Gas tank storage Gas tank storage Gas grid 13
  • 14. Energy storage for energy consumers1. The balancing act of energy storage2. Applications of energy storage at various levels3. Energy storage enables growing need for flexibility4. Practical examples show value of energy storage 14
  • 15. More flexibility is needed, some options1. Fast controllable centralized power generation, including curtailment of e.g. wind power2. Increase interconnection capacity3. Smart local energy, i.e. integration of DG, demand response, and active participation of end-users4. Energy storage 15
  • 16. Energy storage adds value to energy sector Renewables: System operations: Decoupling demand Frequency control and supply Spinning reserve Absorb unpredicted Trade & Power Generation: Balancing fluctuations Control / load following Control and Energy management integration Peak generation Load levelling T&D: End use (industry) : Asset management UPS / Ride Through / Shut down Voltage control Peak shaving Power quality Optimization of energy purchase Grid stability by load shifting Reactive power 16
