Abstract: More than two-thirds of Russia's territory is remote from the centralized power supply system, and that is where the main mining areas are located, as well as a large number of remote settlements. Despite a noticeable increase in the use of autonomous hybrid complexes, there are still problems associated with their design, technical implementation and operation, which are due to the variability and unpredictability of the wind flow. Accurate modeling of autonomous hybrid complex with a wind turbine is an urgent task, the solution of which will improve the efficiency of design and assessment of the life cycle of such systems. However, modern models are presented in a considerably simplified version. This paper deals with the problem of improving the accuracy of modeling energy storage systems as a part of autonomous hybrid complexes based on wind power plant with a diesel power plant. The article provides the rationale for the problem and describes mathematical expressions for modeling energy storage systems. The results of modeling show the discrepancy between the energy storage system's contribution up to 25 % and diesel fuel consumption up to 9 % between the author's and typical models. The dependence of these discrepancies on the capacity of wind power station and the energy storage system capacity was established

Key words: autonomous hybrid complex wind power plant diesel power plant energy storage system battery degradation
