Meshed HVDC grids
Meshed and multi-terminal HVDC grids are a low impact, cost-effective method for integrating large scale and remote renewable energy resources. While HVDC projects are limited by onshore grid compatibility and a lack of interregional and international cooperation models, HVDC grids in Asia have demonstrated their technical feasibility.
We explore various methods for HVDC grids and potential barriers to their implementation.
In this chapter, DNV's Technology Progress Report covers:
- Renewable energy integration
- Connection concepts
- Interoperability of onshore and offshore grids
The envisaged multi-purpose, multi-actor, multi-vendor, multi-national, and multi-terminal HVDC grids will not be planned, designed, and built all at once.
Instead, they will grow in a step-wise, organic fashion. The equipment and systems require technical, regulatory, and economic compatibility and interoperability. This should be achieved through a set of explicit technology and purpose-agnostic minimum requirements which all actors in the super-grid development adhere to. This will require far-reaching coordination on many different levels. Policy makers, grid planners, and designers will need to collaborate to determine regulatory agreements, functional requirements, technical parameters, and project aspects.
