About FlexH2 Project

The project intends to explore the application of pure dc collection technology and integration in offshore wind farms and green hydrogen production. The research project is to start on January 1st, 2024 and will last four years.

FlexH2.0 is based on two key technological innovation pillars: (1) High-performance DC/DC power conversion technology and (2) a reliable control scheme for the offshore wind-to-hydrogen system. This project will explore the optimal design and control solutions for a cost-effective and reliable offshore wind-to-hydrogen system. FlexH2.0 also demonstrates the feasibility of the dc power conversion and collection technology at medium-voltage and GW levels, boosting the application of dc technology in commercial projects.

About this position

This PhD position aims to develop the second innovation pillar of the FlexH2.0 project, .i.e, a reliable control strategy for the wind-to-hydrogen system.

The FlexH2.0 offshore wind-to-hydrogen system is based on a pure dc grid structure, which is more sensitive to the fluctuation of input power and bus voltage. A fast and accurate control response is essential to ensure the balance between wind power and consumption power. However, the slow response of water electrolyzers increases the difficulty of realizing the supply-demand power balance. Besides, the black start-up and fault-handling schemes should also be researched to constitute a reliable and feasible control framework for the commercial offshore wind-to-hydrogen system.

The expected results of the PhD project will be as follows

• Continuous operational control strategy for the offshore wind-to-hydrogen system in different operation scenarios.
• Modeling and parameter design of controllers considering stability issues.
• Reliable black-start and fault-handling schemes.
• EMT simulation verification and control platform development

1. System-level structure design and interface requirements

• Functionality design of offshore wind-to-hydrogen system with pure dc structure
• Design of system-level structure for offshore wind-to-hydrogen system
• Classification of operation scenarios and the constraints/requirements for control schemes
• Verification through EMT simulation

2. Continuous control strategy for the offshore wind-to-hydrogen system

• Review and comparison of existing control schemes
• Continuous operational control strategy for different scenarios
• Modeling and parameter design of control loops considering stability issues
• EMT simulation studies and verification

3. Black-start and fault-handling schemes

• Reliable black-start method
• Configurations for fault protection equipment and fault-handling strategy
• EMT simulation studies and verification

4. Experimental Verification in MV-KW FlexH2.0 Concept Demonstrator

• Controller design of down-scale demonstrator platform.
• Validation of system-level control strategies in continuous operation mode.
• Validation of black-start and fault-handling schemes.
