DELIVERABLE 1.1 | MARCH 2023
Introduction of the report
High Voltage Direct Current (HVDC) technology has become integral to the functioning of multi-terminal multi-vendor (MTMV) grids, necessitating thorough interaction studies. These studies are critical due to the intricate network of stakeholders involved, including vendors, real-time simulation laboratories, system owners, developers, operators, and Transmission System Operators (TSOs).
HVDC in Multi-Terminal Multi-Vendor (MTMV) Grids: Stakeholder Dynamics
In MTMV HVDC grids, stakeholders, such as TSOs, vendors, and developers, collectively contribute to the design, manufacture, operation, and maintenance of HVDC assets. TSOs, acting as overseers of electricity transmission and distribution, can be single or multiple entities managing the grid on behalf of one or more system owners. Developers, too, play a significant role in planning and constructing HVDC infrastructure, potentially becoming partial owners of the system.
Challenges in Multi-Vendor HVDC Projects: Unraveling Interactions
As the number of HVDC projects increases, addressing challenges in multi-vendor collaborations becomes imperative. Particularly in the context of multi-terminal HVDC grids, where interactions are not yet fully assessed, new dynamics emerge. The involvement of multiple vendors requires a clear redefinition of roles and responsibilities for each stakeholder to ensure project success.
Navigating Complexity: Ownership and Liability in MTMV HVDC Grids
The intricate ownership and responsibility landscape in MTMV grids can pose challenges in identifying and assigning liability during problems or failures. Thorough interaction studies become even more crucial to identify and mitigate potential issues arising from complex ownership and operational structures.
Collaborative Approach for Safe Operation: Coordination and Communication
Effective communication and coordination among stakeholders are paramount for the safe and efficient operation of HVDC assets. Determining the timing, scope, and deliverables of TSOs for interaction studies, as well as vendors’ contributions, is crucial. The question of whether one vendor can provide a model or replica used by another vendor for these studies is addressed in WG4, focusing on investment blocks.
Legal and Technical Perspectives: Ensuring Compatibility
While WG1 addresses technical aspects, WG2 task 2.1 delves into the legal perspective, specifically Intellectual Property (IP) and confidentiality for vendor control models. Establishing a legal framework, including Non-Disclosure Agreements (NDAs) and measures to prevent reverse engineering, is imperative for secure collaboration.
Differentiating HVDC Projects: New Systems vs. Expansions
It is essential to differentiate between two types of MTMV HVDC projects: the creation of an entirely new system and the expansion or interconnection of existing HVDC links. These distinctions may warrant different requirements, leading to the application of distinct studies and methodologies.
Role of Integrators: Conducting Crucial Interaction Studies
Interaction studies play a pivotal role in ensuring the proper functioning of HVDC grids within the power network. Integrators bear the responsibility for conducting these studies, and identifying potential issues or conflicts with other power network components. In case of a vendor causing interoperability issues, the integrator proposes solutions that must be accepted and endorsed by the vendor, highlighting the vendor’s commitment to the project and alignment with its requirements.
