Low-power solar stations on dam surfaces of reserrvoirs

Agriculture in the Republic of Uzbekistan is based on irrigated agriculture, therefore, not all rivers existing in the country fully satisfy the needs of consumers, and water resources are accumulated mainly from reservoirs. From this point of view, the strength of the dams of these reservoirs has been studied in detail. However, in most cases, the external slopes of the dams of these artificial hydraulic structures are not used. This, in turn, requires new scientific solutions for the development of solar energy in Uzbekistan, where the amount of solar radiation is quite large. As an example, to study this problem, the amount of seasonal solar radiation in the southeastern region of the republic was obtained using simulation values using a geographic information system on the ArcGIS 9.3 platform and a seasonal map of solar radiation was developed. At the same time, to ensure the efficient operation of solar photovoltaic installations made of photovoltaic cells based on semiconductor silicon materials, it is proposed to use the external slope of the Talimarzhan dam located in this territory. This, in turn, makes it possible to eliminate the problem of preventing the drop in the coefficient of performance (COP) of solar photovoltaic cells, which is an important working part, with an increase in one of the most negative external factors - temperature. The results show that based on the generated direct electric current from the solar photovoltaic station, the following can be supplied: lighting system for the reservoir, uninterrupted power supply of synchronous motors installed at pump station №7, consumers of auxiliary needs of the hydroaccumulative power station, which is planned to be installed in the reservoir, potential electricity consumption, consisting of from tourism services infrastructure to the development of ecotourism.
