Abstract

The article examines the main trends in the use of renewable energy sources in the world. The article examines the main trends in the use of renewable energy sources in the world. The use of renewable sources is associated with the depletion of reserves of carbonaceous minerals and a decrease in greenhouse gas emissions into the atmosphere. The article presents the main, according to the authors, reasons for the incorrect determination of the potential of small hydro resources in the Republic of Tajikistan. In recent years, many small hydroelectric power plants have been built, which are ineffective. For this, the authors propose a more detailed study of the watercourse regime and the determination of its potential for the minimum and maximum tributaries and the possibility of its use, the influence of hydrological, socio-economic factors on the determination of the potential of small rivers during the construction of small hydroelectric power plants. Zoning of small watercourses is proposed for a more detailed determination of the watercourse capacity and the possibility of constructing small hydroelectric power stations on them. The influence of altitude above sea level on the output of the rated power of installations of renewable energy sources is considered. As it shows, the experience of operation and the above statistical analysis at the existing small hydroelectric power plants with an altitude of SHPPs above sea level, their nominal capacity will decrease. The decrease in the nominal output power of small hydroelectric power plants with an air-cooling system is associated with the rarefaction of atmospheric air.

Highlights

Tajikistan, like most countries, does not have its own minerals, and all energy is generated using renewable energy sources, especially hydropower
The use of renewable energy sources has most of the unsolved problems associated with determining the potential and modes of operation of renewable energy sources depending on their geographical location
Since Tajikistan, in most of its cases, uses hydro resources, it is necessary to develop a unified approach to solving the problems of using small hydropower resources

Summary

Introduction

Tajikistan, like most countries, does not have its own minerals, and all energy is generated using renewable energy sources, especially hydropower. The use of renewable energy sources has most of the unsolved problems associated with determining the potential and modes of operation of renewable energy sources depending on their geographical location. There are still many unresolved problems in using renewable energy sources and a unified approach to solving all the shortcomings. The design of renewable energy installations requires both technical and economic, and social solutions. Since Tajikistan, in most of its cases, uses hydro resources, it is necessary to develop a unified approach to solving the problems of using small hydropower resources
