10:10Technology insight: Grid connection requirements and grid code compliance of wind turbines - turbine manufacturer’s view

• Overview of grid code requirements for wind energy in general (e.g. reactive power capability, LV RT)
• Grid code assessment and evaluation of technical requirements (e.g. requirements for wind power plants or wind turbines)
• Impact of specific grid codes on the turbine technology and design (e.g. reactive current injection during voltage dips)
• Manufacturers' need for structural harmonisation of grid codes

12:40 Networking luncheon

14:00Case Study: The Challenges of building a UK Round 3 zone offshore transmission network

• SPR with our development partners are developing a 7200MW UK Round 3 Project
• The zone has a transmission connection agreement for the full capacity phased over several years
• The zone has 3 onshore system connection points with numerous onshore and offshore cable routes in excess of 100 km each
• The optimal design of the offshore transmission system must consider available technologies, capital costs, availability, regulatory issues, and consent issues

15:20 Refreshment break & networking

15:50Technology insight: Connection of offshore wind farms using the new generation of Voltage Sourced Converter (VSC) HVDC technology

• HVDC is the optimum economic and technical solution for the far offshore
• VSC technology ensures grid code compliance at the onshore station
• V SC provides a flexible solution for future offshore grids
• HVDC controls and turbine controls need to be properly analysed to avoid adverse interactions
