Carbon Trust : Controller Interaction and Grid Stability Studies

In 2008, Carbon Trust (UK) commissioned the collaborative R&D and deployment programme in partnership with leading offshore wind developers. The aim has been to reduce offshore wind cost, develop best practices and new industry standards across the different aspects of offshore wind development.

The tender on “HVDC-connected OWFs and controller interaction and grid stability study” was launched to implement a common framework and method for all operators and manufacturers. The main objective of this project is to develop a framework to better understand the key factors that contribute to control interactions, as well as to establish a study methodology to identify potential concerns, efficiently derive mitigation measures, and verify safe operation of equipment.

The scope of work performed by RTE international engineers includes:
– Developing the methodology to study interactions between HVDC-connected OWFs and FACTS devices,
– Developing a scope of studies to be performed in order to investigate interaction phenomena,
– Performing extensive dynamic EMT studies with generic models of the HVDC link and WTG provided by the client,
– Performing necessary interaction studies for multi-vendor HVDC systems and understanding potential mitigation actions and their costs.
