HVDC-WISE is a 3.5-years European project supported by the European Union’s Horizon Europe programme, which started in 2022. Main goal of the project is to propose a number of reliable and resilient HVDC grid configurations that will lay the groundwork for a future integrated EU-GB transmission system. The project gathers 14 front-runner members bringing together academia, research institutes, a consulting service company and five TSOs. This allows a focused consideration of a range of potential R&R solutions, answering key resilience questions that are applicable to all HVDC developments.
To achieve this goal, the HVDC-WISE project is pursuing the following five milestones:
- Develop a complete reliability-&-resilience-oriented planning toolset with appropriate representation of different HVDC-based grid architecture concepts in hybrid AC/DC grids
- Identify, propose and compare different HVDC-based grid architecture concepts aiming to address TSOs’ reliability and resilience needs for widespread AC/DC systems
- Identify and assess emerging technologies for HVDC-based grid architecture concepts needed for the deployment of widespread AC/DC transmission grids
- Validate the toolset and grid architecture in an industrially relevant environment
- Prepare for the adoption and deployment of these proposed solutions by the industry
Role of the ACS in the project
As the integration of power electronics (PE) increases, the network experiences issues that can only be observed using more detailed models than RMS ones. The lack of adapted tools entails the risk of obtaining inaccurate results that can lead to non-optimal planning and/or operation of the AC/DC network.
In this context, ACS will extend their Real-Time power systems simulator based on the dynamic phasor approach (also called frequency shift approach) DPsim to simulate large-scale systems with high integration of HVDC and other PE devices. Later, this tool will be used to analyse the advantages of the dynamic phasors approach for the simulation of power systems with high penetration of PE devices against the RMS based simulators commonly used for transient stability studies.
Furthermore, ACS leads in WP4 the task 4.3 which will propose an open-access standardized library of HVDC models and an associated extension to grid data standards (such as IEC CIM/CGMES), to facilitate the grid models/data exchanges between different simulation tools.
The project has received funding from the European Union’s Horizon Europe programme under grant agreement no 101075424.
