AC fault dynamic studies of islanded grid including HVDC links operating in VF-control
VSC-HVDC link can operate in VF-control (or grid-forming mode) when connected to a weak or islanded network to overcome the PQ-control (or grid-feeding) limitation. Up to now, the VF-control represents a challenge due to static and dynamic ...
Implementation of a dedicated control to limit adverse interaction in multi-vendor HVDC systems
This paper reports on recent work performed in the framework of European project Best Paths DEMO #2, where interoperability in multi-vendor VSC-HVDC systems is investigated. In this four-year project, three major HVDC suppliers provided det...
Symmetrical VSC monopole scheme alternative grounding circuit arrangements
VSC symmetrical monopole grounding circuit with a focus on necessity of the grounding, overview of the existing topologies and a proposal of alternative grounding circuits is discussed in this paper. The key design concepts, advantages and ...
The changing landscape of Great Britain's electricity interconnector usage
The ways in which Great Britain's interconnector have been utilised in recent years. This paper analyses the power flows across the four operational interconnectors (IFA, Moyle, BritNed and EWIC), identifyin and discussing the reasons for t...
NorthConnect HVDC interconnector
NorthConnect is a project set up to develop, consent, build, own and operate an HVDC electrical interconnector between Peterhead in Scotland and Simadalen in Norway. The 665km long, 1400MW interconnector will provide an electricity transmis...
Development of HVDC offshore grids in the European system: Long-term transmission expansion analyses
This paper provides an assessment to optimise the development of HVDC offshore grids in the North Seas in a 2050 time horizon. This is carried out by the application of a specific approach to find the global optimum between the development ...
Kriegers Flak combined grid solution — novel double use of offshore equipment
The Krieger Flak Combined Grid Solution (KF CGS) will be in commercial operation from early 2019. Major novelty of the project is the combination of the existing and scheduled offshore wind power grid-connection systems with an interconnect...
The design and development of a 2000MW HVDC interconnector between Great Britain and France
AQUIND interconnector will provide a 2000MW HVDC electricity link between the electricity networks of Great Britain (GB) and France. To comply with the connection limitations in GB the link is being developed as 2 independent 1000MW symmetr...
Impact of DC grid contingencies on AC system stability
In order to reliably and safely operate future multi-terminal HVDC grids, different protection strategies are currently being developed and presented in the literature. Especially for large DC grids, it is important to investigate how the c...
Impact of model complexity on mixed AC/DC transient stability analysis
Model complexity may have a significant impact on transient stability results of mixed AC/DC systems. The dynamics of various mixed AC/DC models with a focus on different generator orders and multi-level modular converter (MMC) VSCHVDC mode...
