Fault ride-through challenges of colocation of renewable hydrogen power plant

The integration of high shares of renewable energy in the EU poses challenges such as grid stability, congestion, and balanci ng intermittent supply. A key issue is the costly and time-consuming need for grid upgrades to accommodate high renewable infeed. This paper proposes co-locating renewable hydrogen production with wind and solar plants as a solution, optimizing grid capacity use and reducing reliance on extensive grid expansions. The major contribution of this paper is the analysis of the technical and economic benefits of co-locating GW-scale renewable hydrogen, wind, and solar facilities. This approach enables direct balancing of renewable generation with hydrogen consumption, minimizing grid impacts. However, challenges arise from the interaction of power electronics converters, which can affect power quality and grid stability. The paper provides a detailed assessment of the electromagnetic transient (EMT) impacts of such co-location, highlighting the need for improved grid-following/forming technology and addressing dynamic stability issues. The findings offer critical insights into the design of integrated renewable energy systems and recommend further research to ensure safe and efficient operation during normal and fault conditions.
