With the growing share of renewable sources in the electricity grid of Ukraine, negative impact on the quality of electricity and on the grid itself begins. One of the options for efficient integration of renewable sources into the power grid is to accumulate this energy with subsequent use. Since the main problem of renewable sources is inconsistency and pulsation over time, it’s accumulation in such periods is an acceptable option. In Ukraine, the largest share of output per year is occupied by wind power plants, which are mainly located in the south of Ukraine. It is there the concentration of large wind power stations causes the unsteady operation of the electric network, which in turn leads to their shutdown at large pulsations of generation of electric energy. The accumulation of wind energy is possible in various designs, but in this study an option is explored with the accumulation of this energy for subsequent use through a hydraulic turbine. That is, the process of converting wind energy into quantitative indicators of water accumulation over a specified time will be researching. As a research object, a wind pump installation will act. The simulation of this process will be based on a combination of three components: a wind model, a wind turbine model, a pump model. The simulation will be carried out for various pump capacities at a constant wind power level to determine the most efficient version of the wind pump installation. For the ratio of different variants of the wind pump installation with different pump capacities, relative units of measurement will be used, since the characteristics of the pumps in relative units are identical within the same class. The parameter that will be evaluated for the operation of the wind pump installation will be the annual value of the performance of this installation in per cent for the annual distribution of wind energy for the selected region. The operation of the installation will be modeled only for its nominal operating mode, taking into account wind ripples and constraints in modeling the operation of the wind turbine and the pump from the experience of their operation.
