Abstract.
One of the directions of modern development of renewable energy technologies in Russia is 
associated with the expansion of their application as part of the own needs of power plants. This article 
examines the study of the connection of renewable energy sources (RES) as part of the own needs of 
micro‑ hydroelectric power plants. The analysis of possibility of power supply of own needs of micro‑ 
HPP by wind power installation with use of the frequency Converter for the purposes of regulation of 
tension of own needs of station was carried out. The first part of the article is devoted to the analysis of 
publications on the current problem of the use of small and micro‑ hydroelectric power plants, as well 
as the description of the purpose and objectives of the study. The second section of the article presents 
mathematical models describing the connection of the wind turbine with a frequency Converter to work 
together with consumers of the station's own needs, for which the function of voltage regulation in the 
network is supposed to be performed. The law was formulated and an algorithm was constructed for 
the operation of the wind turbine with a load as part of the station's own needs. Note that this algorithm 
assumes continuous operation of the wind turbine without switching it according to the scheme of 
automatic reserve input, which leads to an increase in the installed capacity utilization factor. In the 
third part of the article the oscillograms of transient processes in the mode with and without wind 
turbines are considered. The short- circuit mode on the load and the influence of the wind turbine on 
the value of the recharge current are also considered. And in conclusion, the main conclusions on this 
work are formulated.
Keywords:
