Using hydrogen electrolyzer power electronics to balance high share of wind power

Wind power has grown strongly in recent years and is expected to continue to increase significantly. On the demand side, there is a strong trend with significantly more hydrogen electrolysis in mainly the mining and steel industry.

In a power system, a continuous balance is maintained between production and consumption. In the Nordic power system, this is currently handled mainly by hydropower. However, depending on the electrolysis technology and power electronics interface to the power system, this flexible consumption could contribute significantly and simplify the increase of large amounts of wind power.

When the current plans for Hybrit and other corresponding project are realized, this means several GW of fast and flexible consumption and many days or weeks of storage.

The aim of this project is to develop and evaluate different types of power electronic interfaces, with and without batteries, suitable control mechanisms for system services and value for wind power integration.
