Abstract

Vloga vodikovih tehnologij v elektro-energetski preskrbi se osredotoča na uporabo vodikovih tehnologij za pretvorbo in shranjevanje električne energije. Raziskava izhaja iz potrebe po uravnoteženju proizvodnje in porabe električne energije, zlasti pri obnovljivih virih, kjer je proizvodnja odvisna od različnih dejavnikov. Delo je del širšega projekta, ki se ukvarja z optimalnim vključevanjem vodikovih tehnologij v elektro-energetski sistem in trg. Pomen vodikovih tehnologij za elektro-energetski sistem je uravnavanje proizvodnje in porabe električne energije ter zmanjševanje odvisnosti od tradicionalnih virov energije. Ključne komponente vodikovega sistema so elektrolizer, hranilnik vodika in gorivna celica. Podrobno so opisane fizikalne osnove delovanja vsake komponente, vključno z matematičnimi modeli. Razvit model digitalnega dvojčka vodikovega sistema omogoča pretvorbo električne energije v vodik s pomočjo elektrolize vode, shranjevanje vodika ter pretvorbo nazaj v električno energijo s pomočjo gorivne celice. Model temelji na fizikalnih zakonih posameznih elementov in je bil implementiran v okolju Matlab ter nato prenesen na programirljiv logični krmilnik Siemens Simatic za delovanje v realnem času. Za programiranje je bilo uporabljeno orodje TIA Portal. Za simulacijo so bile uporabljene numerične integracijske metode, točneje Eulerjeva metoda. Eksperimentalni preizkusi so vključevali ročni izračun pretoka vodika in preverjanje delovanja sistema v različnih intervalih. Rezultati so pokazali skladnost med modelom in teorijo ter pripomogli k razumevanju vloge vodikovih tehnologij v elektro energetskem sistemu.

Secondary title: Real-time hydrogen energy storage system digital twin
Secondary abstract: The role of hydrogen technologies in the electricity supply focuses on the use of hydrogen technologies for the conversion and storage of electrical energy. The research stems from the need to balance the production and consumption of electrical energy, especially with renewable sources, where production depends on season, time in day and weather. The work is part of a broader project dealing with the optimal integration of hydrogen technologies into the electrical energy system and market. The significance of hydrogen technologies for the electrical energy system lies in balancing the production and consumption of electrical energy and reducing dependence on traditional energy sources. The key components of the hydrogen system are the electrolyser, hydrogen storage, and fuel cell. The physical principles of operation of each component, including mathematical models, are described in detail. The developed digital twin of the hydrogen system enables the conversion of electrical energy into hydrogen through water electrolysis, hydrogen storage, and conversion back to electrical energy using a fuel cell. The model is based on the physical laws of individual elements and was implemented in Matlab and then transferred to programmable logic controller Siemens Simatic for real-time operation, using the TIA Portal for programming. Numerical integration methods, specifically the Euler method, were used for simulation. Experimental tests included manual calculation of hydrogen flow and verification of system operation in various intervals. The results showed consistency between the model and theory, contributing to the understanding of the role of hydrogen technologies in the electrical energy system.
