  1. Balancing in Microgrids And the role of a DSO Drs. J.H. Blom MBE

  2. Jos Blom Info Energy Life

  3. Alliander Involved Trusted Best Innovation Sustainability Local

  4. Flexibility - Balance Transfer P2G / P2H Transport Demand Production Storage

  5. Flexibility - Balance Transfer Transport Demand Production Storage

  6. Flexibility - Balance Transfer Production Transport Demand Storage

  7. Drivers for Microgrids

  8. Microgrid risks Island modes: controlled  grid outage, power on synchronization when grid on uncontrolled  switch off grid, still power on Danger for labour Short Circuit Ground fault Power quality

  9. Solutions

  10. Energy Storage Definition Value Role Joule / Watt Joule / Watt

  11. Energy Storage Definition Value Role Joule / Watt Joule / Watt

  12. Electricity storage world wide

  13. Value off Electricity Storage Production & Trading Transmission & Distribution End user (B2C, B2B) Optimizing Demand - Supply 1 Base load operation 15 Time of use 2 Short peaks (APX) 3 System balancing Minimizing OPEX and CAPEX 4 Deferral investment production capacity 8 Deferral investment production capacity 16 Lower connection capacity 9 Reduction Gridlosses 17 Minimizing AC/DC Conversions Better turbine efficiencies 5 10 Alternative transport Integration sustainable production 6 Support sustainable production 11 Congestion management 18 Support decentralized production 7 12 Power Quality Black start facilities Support outage 13 Frequency and reactive control 19 Self control More reliable energy 14 Voltage control 20 The value of electricity storage 14

  15. Pilot: Solar Connection

  16. Results

  17. Results

  18. Consequences of growing renewables House hold New household Solar How new customers behave How energy markets view all customer

  19. Powermatcher gives you an alternative increase your use here By moving load from this period

  20. How it works Auctioneer calculates price where supply=demand market Sends back market price Send bid on how much energy at what price Bid curve power Bid curve power Appliance switched on if in the money Appliances Calculate energy need

  21. The cool part • Bottom up approach means the appliances (you) decide if/how much external influence you accept • Appliances tell how much flexibility is available at what conditions. (no surprises) • No mismanagement of devices or unexpected lost comfort • Works in your home just as good as for a (local) market

  22. The tricky part • You need a standard format for the (energy) bid • Fitting it in millions of appliances means it should cost next to nothing • Appliances manufacturers and energy providers need to cooperate Free download

  23. Technical structure

  24. Overcoming the Challenges Of Balancing Intermittent Renewables Within A Microgrid • Managing the delicate balance of supply and demand while providing the necessary electrical safety functions • Forecasting the supply of wind and solar • How to use storage in rural vs. urban scenarios with intermittent renewable?
