Abstract
West Pomeranian University of Technology in Szczecin, as a leader, along with the University of Szczecin and Enea Operator LLC, is implementing the R&D project ‘Development of an intelligent and automatic system for stabilising the operation of power distribution networks based on modular installations of a hydrogen energy buffer with the intention of utilising hydrogen’. Its goal is to build the first hydrogen energy buffer in Poland, whose task will be to stabilise the parameters of the power grid. The operating conditions of the power grid, and the impact of the energy buffer system on its stability, have been determined. The nominal parameters of the buffer elements were calculated and the place of its installation and the assumptions for its operation have been indicated. The buffer will be located in the 110 kV / 15 kV substation.
