DEMONSTRATION 4 "STORM MANAGEMENT"

4

DEMO 4 STORM MANAGEMENT (Leader: ENERGINET)

• Demonstrate shut down of wind farms under stormy conditions without jeopardizing safety of the system.

Main objective

• Horns Rev 2 (200MW).

• Flexible turbine control.

• Storm front forecasts.

• Investigate cost of changed production associated with the planned down regulation.

• Coordinate wind farm control with HVDC interconnector control and with hydro power plant operation.

Approach

OFFSHORE WIND POWER VARIABILITY HYDRO POWER POTENTIAL

GRID RESTRICTIONS

11

Replication work packages: barriers and up scaling

WP 15: Economic impacts of the demonstrations, barriers towards scaling up and solutions (Leader: IIT)

• Assess the local economic and/or technological impact of each demo.

• Identify the barriers to scale-up the outcomes at a member-state or regional level, and propose solutions to overcome these barriers.

WP 16: EU wide integrating assessment of demonstration replication potential (Leader: DTU Wind Energy)

• Assess portability of voltage control, frequency control and VPP model to other countries and regions.

• Evaluate North European 2020 offshore wind power variability, hydro potential and barriers and grid restriction studies.

• Pan European economic impact study.

WP 17: EU Offshore barriers (Leader: TENNET)

• Address the issues of smart licensing of submarine interconnectors with and without wind parks in the North Sea and Baltic Sea.

• Identify common licensing barriers and propose regulatory measures.
