  9. 9. Electricity Market Structure-Denmark • Liberalized market and a part of the Nord Pool market • Commercial Market: The commercial markets are mainly about establishing an energy balance per hour – Day ahead (ElSpot) market – Hour ahead (Elbas) market • Ancillary services: Purchased by the Transmission System Operator (TSO) i D O in Denmark i k i.e., E Energinet.dk, f i dk from selected central power plants (with must-produce- contracts), to ensure stable and reliable operation of the electricity systems systems. 9 Electric Vehicle Integration Into Modern Power Networks 2010-09-22

  30. 30. Conclusion • EV’s will play an interesting role in a future power system caused by the EV s battery power storage provided in the power system, i.e.V2G . • An intelligent architecture is needed for control of charging, G2V and V2G system services. • Day ahead Market: Small economical benefits using the car as a flexible load • Ancillary services: significant payment can be expected from the TSO. An intelligent systems for providing ancillary services must be developed. g y p g y p • New providers of ancillary services will increase the competition in a profitably market causing expectations to a decrease in prices. • Considerably more vehicles are needed to offer down regulation (charging) compared to up regulation (V2G) because batteries will (V2G), normally be higher charged and discharged. 14 Electric Vehicle Integration Into Modern Power Networks 2010-09-22
