  1. EWEA 2012SESSION: ADEQUATE ELECTRICITY MARKET DESIGN CONCEPTS FOR WIND POWER INTEGRATIONProactive participation of wind turbines in the balancing marketsPresenter: Anders N. Andersen, EMD International A/S

  2. The Danish Transmission System Operator has financed a real case test about Proactive participation of wind turbines in the balancing markets.Participating companies in this test: • EMD International A/S (www.emd.dk) • Danish Wind Industry Association(www.windpower.org) • Nordjysk Elhandel (www.neas.dk) • Inopower (www.inopower.dk) • Vindenergi Danmark (www.vindenergi.dk)

  3. You will in this presentation meet: • The need for wind turbines being proactive in the balancing markets. • New Danish regulation for wind turbines participating in the Tertiary reserve market. • Live test of activation of wind turbines in the Tertiary reserve market. • Simulated profit for wind turbines being activated in the Tertiary reserve market. • Proposal for improved organization of the balancing markets, allowing increased competition in these markets.

  4. The need for wind turbines being proactive in the balancing markets is shown in www.emd.dk/el

  5. New Danish regulation for wind turbines participating in the Tertiary reserve market

  6. A Balancing Responsible Party informs the TSO about: • Hourly energy notification (hourly energy amounts traded) • Power schedule at 5-minute intervals (updated when necessary)

  7. Settlement of imbalances: • Imbalances in the hourly energy notification is settled with the activation prices in the Tertiary reserve market. • Imbalances in the power schedule is settled with the activation prices in the Secondary reserve market.

  8. The Danish TSO has recently changed its regulation in order to facilitate active participation of wind turbines in the Tertiary reserve market.

  9. A Balancing Responsible Party for wind turbines used actively in the markets informs the TSO about: • Hourly energy notification (hourly energy amounts traded) • Special 5-minute time series showing the number of MWs (installed capacity) of the total portfolio of operational wind power plants that have been closed down.

  10. Settlement of imbalances for wind turbines: • Imbalances in the hourly energy notification is settled with the activation prices in the Tertiary reserve market. • Imbalances in the power schedule is NOT settled.

  11. Live test of the economic benefit for a wind farm in operation of 21 MW that places bid by offering downward regulation to the TSO

  12. IT-solutions for activating wind turbines in the Tertiary reserve market

  13. Short-term forecasting of wind productions

  14. Simulated profit for wind turbines being activated in the Tertiary reserve market.

  15. Proposal for improved organization of the balancing markets, allowing increased competition in these markets.

  16. The electricity directive creates the legal framework for the organization of the balancing markets

  17. Proposals for the good organization of a balancing market (being most impor-tant for the Tertiary Reserve-market): • Split the market into an availability market and an activation market. • Make the market assymmetric, allowing to offer only positive or negative power. • Organize the market as a Marginal price market and not as a PayAsBid-market.

  19. Summing up about proactive wind turbines in the balancing markets: • Most of the balancing of wind productions is to be made in the Tertiary reserve market • Organizing the balancing markets in the right way, will allow an increased competition in these markets, and the wind turbines themselves may even earn money when participating in these markets – and at least be protected against big imbalance costs.
