ABSTRACT

A group of eight Transmission System Operators with a generator company, manufacturers and research organisations, propose 5 demonstration projects to remove, in 4 years, several barriers which prevent large-scale penetration of renewable electricity production in the European transmission network. The full scale demonstrations led by industry aim at proving the benefits of novel technologies coupled with innovative system integration approaches: a scaled down model of generators connected to a HVDC link is used within a new testing facility to validate novel control strategies to improve the interaction between HVDC links and wind turbine generators.

The implementation of a full scale, hardware-in-the-loop test setup in collaboration with worldwide market leaders of HVDC-VSC technology explores the interactions of HVDC VSC multiterminal control systems to validate their interoperable operations. Strategies to upgrade existing HVDC interconnectors are validated with the help of innovative components, architecture and system integration performances, to ensure higher RES penetration and more efficient cross border exchanges. Full scale experiments and pilot projects at real life scale of both installation and operation of AC overhead line repowering technologies are carried out to show how existing corridors can see their existing capacity increase within affordable investments.

The technical feasibility of integrating DC superconducting links within an AC meshed network (using MgB2 as the critical material) will be tested at prototype scale, thus proving that significant performance improvements have been reached to enable commercialization before 2030 The experimental results will be integrated into European impact analyses to show the scalability of the solutions: routes for replication will be provided with benefits for the pan European transmission network and the European electricity market as soon as 2018, in line with the SET plan objectives.
