One of the trends in the development of the electric power industry in the world is the use of renewable resources. In recent years, the development of hydrogen energy has been widely discussed, which, when combined with renewable energy sources, makes it possible to obtain “green” hydrogen. One of the promising solutions for obtaining green hydrogen is the development of wind energy-hydrogen systems. However, one of the limiting factors, in addition to economic aspects, are technical limitations. Sustainable hydrogen production is complicated by the variability of wind energy. In addition, energy systems with a predominant share of wind power units have a low total inertia value. Consequently, such systems become more sensitive to changes in load modes in the grid and become less stable in emergency modes. Together, these facts reduce the reliability of wind energy-hydrogen system. The paper proposes to increase the stability of wind energy-hydrogen system and power system as a whole to apply synthetic inertia for wind power plants. It is shown that by adjusting the parameters of synthetic inertia can provide not only the required inertial response, but also increase the dynamic stability of the power system and as a consequence wind energy-hydrogen system. The influence of the measurement window time and calculation of the frequency change rate, which is important in certain modes, is also investigated.
