Project

The aim is to obtain knowledge of nonlinear loads which could cause unwanted dynamics or stability issues for the DC-microgrid. This leads to the investigation of the nonlinear loads: Constant Power Loads and Reversible Solid Oxide Cells.
The design of a suitable DC-DC converters and control systems are investigated to fulfill performance requirements and mitigate stability issues.

This project includes modelling, designing and testing of a 150 kW solid-oxide electrolysis (SOE) system for renewable hydrogen production. The produced hydrogen can be used as a component for future green electro-fuels like ammonia or methanol.

The SOC stacks will be operated by the novel AC:DC control method which enables dynamic hydrogen production due to fluctuating electricity production from wind turbines.

The AC:DC method requires bi-directional power flow of the stacks and dedicated power electronic converters will therefore be developed in this project as well.

When the project is successfully completed, the consortium will have demonstrated manufacturing and operation of a power-to-X plant with AC:DC operation technology. This is an important milestone on the path for megawatt production.
