Power converters: enabling wind turbine integration in the grid

Antonio Moreno Brenes wrote the fifth ReFlexion about one of the technologies we are developing in the FlexH2 project.

Electric energy can present many different forms. It can be as Direct Current (DC) or Alternating Current (AC); it may oscillate at different frequencies, it may present different voltage levels, etc. In a wind farm, many conversion steps are needed, from the electricity produced by the wind generator to the electricity that is finally fed into the electric grid.

It’s about Modular Multi-level Converters

Carl Barker wrote the fourth ReFlexion about one of the technologies we are developing in the FlexH2 project.

Increasing the voltage enables energy transmission over a long distance since it reduces the energy losses. High-voltage (HV) transmission can be in Alternating Current (AC) or Direct Current (DC). For transmitting power over approximately 80 kilometres, typically, HVDC technology is preferred.

It’s about how we feed the electricity into the grid

The third ReFlexion of Dongsheng Yang is about one of the technologies we are developing in the FlexH2 project.

Get insight into how we feed electricity into the grid and how Grid-forming control differs from the current method. 

Iratxe González-Aparicio of TNO and Lucia Beloqui Larumbe of Shell, both work package leaders in the FlexH2 project, will share their expertise, knowledge and experience on hybrid solutions offshore, focusing on the tandem of offshore wind and onshore hydrogen. Join them and others at the Offshore Day on the 4th of June in Rotterdam!

You can witness what the experts have to say about the innovations required to achieve wind energy on demand. 

Dr. Aitazaz Ali Raja from TNO was interviewed about the FlexH2 project during the live stream.

Get insight into the use of transformers and why voltages are increased and decreased in different parts of our utility grid. 

Innovation Origins, a European platform about innovation, start-ups and technologies, published an interview with Dongsheng Yang TU/e researcher about the GROW project called FlexH2.

Our Flexible Offshore Wind Hydrogen Power Plant Module (FlexH2) project starts today. With this project, we will make a significant step in the development of the technology necessary to integrate large amounts of offshore wind energy into the energy system. To aim is to significantly reduce the investment costs for the offshore wind transmission infrastructure and to increase the flexibility for shifting between electricity and hydrogen production.

The Netherlands Enterprise Agency (RVO) announced that the GROW consortium FlexH2 project was awarded a grant as part of the MOOI-SIGOHE tender scheme. The Shell-led research project FlexH2, which stands for Flexible Offshore Wind Hydrogen Power Plant Module, intends to develop and demonstrate technology that will accelerate the scale-up of offshore wind, green hydrogen production and its integration into the energy system. Through this grant, the government is contributing 4 million euros, the partners are investing about 5 million euros in the project. The research project is to start on April 1st 2022, and will last four years.
