Abstract

From the electrical point of view, electrolysers are comparable to wind turbines. Although electrolysers operate as consumers and wind turbines operate as generating units, both affect the electrical grid with their property as power electronics and their perspective capacity in the multi gigawatt range. For electrolysers there are less restrictive guidelines available so far. The development of larger wind turbines has shown that strict regulations are necessary to ensure a safe grid operation. For this reason, electrolysers must be tested in a greater extent than at present in order to achieve grid compliance standards with equal quality. For this standardization research and development projects should be realized. The participation of manufacturers, system operators and research institutes in this process is essential. Within the projects it can be demonstrated which characteristics are most important and how they can be analyzed. In addition, the interaction between electrolysers and other energy system components such as wind turbines, fuel cells or combined heat and power stations must be investigated. The test infrastructure at Fraunhofer IWES has already been implemented for the certification of wind turbines and can now be adapted for the certification of electrolysers enabling a wide range of system studies. Focus lies on electrical integration of electrolysers, but also peripheral hydrogen components such as compressors or storage tanks can be tested in this environment.
