This ensures the effective participation of wind power plants in the process of maintaining the frequency and permissible voltage levels in the energy power system (EPS). Possible methods and ways of reserving the unevenness of RES electricity generation caused by weather conditions are analyzed, and the advantages of hydrogen technologies over others are shown. They are more universal, because hydrogen produced with the help of renewable energy sources can be used as an energy carrier not only in the power industry, but also in other industries. At the same time, the use of hydrogen technologies during the balancing of EPS modes opens up new opportunities for the development of wind and solar power plants in the EPS, as fines and restrictions on the production of RES electricity are reduced. The algorithm for using hydrogen as an energy carrier to reduce the error between the actual and forecasted hourly schedules of generation of wind power plants as part of the balancing group is considered. Mathematical models were developed on the basis of the theory of similarity and the criterion method. This approach, based on the minimum available initial information, provides an opportunity to compare different methods of reserving the uneven generation of wind power plants, to assess their proportionality, and also to determine the sensitivity of costs to the capacity of the reserving methods. Criterion models have been formed that allow for the dependence of costs for reserving the uneven generation of wind power plants on the capacity of hydrogen-type accumulators and on the capacity of the system reserve together with the throughput of power transmission lines. It is shown that similar dependencies make it possible to more reasonably choose certain reservation methods in accordance with the characteristics and requirements of the EPS. Ref. 15. Fig. 2. ER -
