Scope of BestPaths Demo2 : Multi-vendor interoperability for VSC-based HVDC systems
The development of HVDC systems will be : gradual, growing by connecting step by step equipments from different
manufacturers
The interoperability of these equipments is a key issue for DC grids
DEMO 2 : OVERVIEW
+ ?
3
Targets
Explore interoperability conditions for multivendor HVDC systems toward DCgrids based on recent VSC converters.
Interoperability assessment performed on a wide variety of situations(combinations of DC topologies, AC connections, control modes, etc.) and fordifferent conditions (normal operation, fault conditions, special sequences).
Recommendations for standardization bodies and stakeholders of future DCG
DEMO 2 : OVERVIEW
4
Demo 2 partners :
TSOs to define the operational requirements of HVDC systems
Manufacturers to bring there best industrial solutions
Academic to contribute to interoperability studies
In very precise (and tricky!) IP conditions and rules
All partners to bring progress and build the conclusions

DEMO 2 : EXPECTED RESULTS & IMPACT
5
Expected results
To define the driving conditions of safe interoperability of multivendorequipments on a HVDC grid
To develop a two-stage Interoperability assessment process :
EMT simulation using manufacturers models for converters (EMTP-RV)
Real-time simulations with actual control replicas provided by vendors (Hypersim)
…That could be used in a real HVDC grid development process
Recommendations for standardization bodies and stakeholders of future DC Grids
DEMO 2 : ACTIVITIES
6
HVDC Grids simulations
Definition of the combinations of Grid topologies DC, AC and operation conditions (normal operation, fault conditions, special sequences).
Off-line simulations with manufacturers AC/DC converters models ; Specifications for AC/DC converter control system replicas : WP 4
On-line (Hardware in the loop) simulations with AC/DC converters control system replicas provided by the manufactures: WP9
For both offline and real-time simulations
Only for offline simulations
As an option (offline simulation)

Results achieved
Generic converter model (EMTP-RV) to support Tasks 4.2 and 4.3
“By-product” rather than an expected outcome
Guarantee some homogeneity in EMTP co-development (by 7 partners)
