Chair: Nicolaos Cutululis, SP5 Coordinator
The main objective of the session was to establish the state-of-the art in R&D for integration of wind energy into the energy system, and to highlight future research topics and technology development focus. The session consisted of four presentations:
- System integration of offshore wind, where we are & what next – PROMOTioN project, Cornelis Plet, DNV GL
- The future all-dc based wind farms – Ola Carlsson, Chalmers University
- Aspects of relevance for utility scale wind-solar hybrid power plants – Poul Sørensen, DTU
- Towards 100% RES power systems; challenges and opportunities for wind power – Nicolaos A. Cutululis, DTU
The PROMOTioN project is the largest ongoing project focusing on integration of offshore wind and development of HVDC multi-terminal grids. It is widely accepted that HVDC technology and grids will play a major role in further development of offshore wind power. The main conclusion arising is that the ingredients for HVDC multi-terminal grids are ready, with HVDC system integration remaining the main challenge. To overcome this, aspects such standardization, detailed validated high-fidelity models and novel validation & verification methods are needed.
Recognizing the importance of HVDC offshore transmission and grids, future offshore wind power plants could move into incorporating DC technology in their collector system. To do so, research is needed to provide a deep understanding in layout of the future DC-grid and interaction with AC-grid and to understand which are the main driving forces for DC-grid in component level.
Wind-based hybrid power plants have many promising and appealing features. They can reduce the LCoE making use of shared infrastructure, provide more reliable and efficiently ancillary services, reduce the variability and uncertainty of weather-driven generation and provide grid services. The area is fairly new and, at the moment, driven by industry, however there are many opportunities for R&I.
Finally, the opportunities and challenges for wind power moving towards 100% RES power systems were introduced. While the potential is there, the transitions will require that wind power will move from grid-following generator to being grid-forming technology, creating and supporting the grid.
