National Grid is being challenged by offshore wind farm
developers on whether power oscillation damping is required
and the control philosophy that National Grid has specified in
Bilateral Agreements. The knowledge provided by this research
will allow National Grid to justify the control philosophy
included in the Bilateral Agreements as the most effective.
It is important to mention the existing HVDC interconnector
does not provide POD.
It is proposed that Imperial College will undertake work to
establish this understanding and to propose alternative control
strategies that might be practical to apply to a real power
This feasibility project will deliver important knowledge and understanding on the effectiveness of damping with HVDC using different control strategies. This is the key to
underpinning immediate post contract negotiation with offshore wind farm developers for the Celtic Array and Hornsea wind farm.
The objectives of this consultancy project are to:
- assess how power oscillation damping (POD) will
help to damp the low frequency oscillation (LFO) in
- Investigate effectiveness of control strategies for
better stability of the GB transmission network.
