The implementation of small-scale hydropower stations in slow flow micro-rivers: a case study of Uzbekistan

Abstract

Electric energy production in small-scale hydropower stations is attractive from both an ecological and an economical point of view. Technological innovations and measures to lessen environmental impacts make small-scale hydropower stations inexpensive and justified energy sources that provide renewable energy on an independent basis and help not only to protect the environment but also to weaken human dependence on fossil fuels. This study is devoted to finding solutions based on renewable energy technologies and innovations in Uzbekistan. This article is devoted to the development of a water wheel experimental model for the micro-hydroelectric power station. Experimental studies were carried out on the basis of this model and obtained results were used in the preliminary calculations. The results from the calculations showed that the installation can generate 7-11 kWh of electricity per hour, about 168-264 kWh of electricity per day and 61 to 96 MWh of electricity per year.

Advancements in renewable energy sources (solar and geothermal): A brief review

“…Motivated by environmental imperatives and the need for energy security, governments, industries, and research institutions globally have intensified efforts to explore and enhance the potential of renewable energy technologies. The quest for sustainable energy solutions has led to remarkable strides in the development of solar [3,4], wind [5], hydropower [6][7][8][9][10], geothermal [11][12][13], and biomass [14][15][16][17][18][19][20] technologies. These advancements not only promise cleaner energy but also herald economic opportunities and increased energy independence for nations.…”

Development and testing of a laboratory model of a two-turbine small hydroelectric power plant

“…Therefore, researchers are encouraged to conduct research on the use of clean and renewable alternative energy sources such as hydro, solar, wind and geothermal energy [1][2][3][4][5][6][7][8]. The use of water energy has been one of the most important sources of electricity generation for several hundred years, first it was used to obtain mechanical energy for mills, and then to generate electricity [9,10]. At the same time, the role of small hydropower plants in the world hydropower is about 10 percent.…”

Study on the effective use of solar and hydro energy for powering agriculture and water management

“…There are hydropower facilities in sizes ranging from a few Kilowatts (kW) to many Gigawatts (GW). Small hydropower plants, typically in the kW range, are utilized to electrify rural areas in many nations and have a strong potential to be included into the value chain of agriculture in those regions [7][8][9][10][11][12]. The basic operating principle of hydropower, especially small-scale hydropower (up to 1 MW), is as follows: water from streams or rivers flows through a turbine, which rotates and operates machinery (such as pumps, mills, etc.)…”
