Electrical Infrastructure & System Integration
Developing reliable and cost-effective electric power components and system solutions to enable profitable large-scale deployment of offshore wind energy in the North Sea.
Work Package 3 is lead by Eirill Bachmann Mehammer from SINTEF Energy Research and Magnus Korpås from NTNU. Its focus areas are electric power components and system integration of wind energy (WE).
Anticipated results:
- Reliable and cost-efficient electric power components for
energy collection - Optimised electrical architectures and operational solutions
for cost- and energy-efficient grid connection
Hypothesis
Large-scale offshore wind power can be collected, transmitted and integrated in existing electrical
power systems in a cost-efficient and reliable manner.
Methodology and research tasks
Infrastructure
AC-based export systems, thermal-electrical cable models, subsea substations, new component design, models for degradation and lifetime assessment.
System integration
Development of a framework for transient analysis and stability assessment of large hybrid AC/DC power systems offshore, advanced ancillary services provision from WFs, models to identify economically robust offshore grid configurations and improved legal and regulatory framework.
