The necessity of optimal regulation of power generation and consumption in the
energy system of the Republic of Uzbekistan by highly manoeuvrable hydro- and hydro-storage power
plants has been substantiated, their participation in the regulation of energy production process has
been analysed on the example of the daily load schedule of the energy system. The method of
determining the energy characteristics of power plants by solving the problem of optimal distribution
of loads between hydro- and thermoelectric power plants during the day, taking into account the
maximum use of limited water resources. The results of calculations of load distribution between
hydro- and thermoelectric power plants in order to equalise the schedule of energy loads of thermal
power plants in the power system with an increase in the non-uniformity coefficient from 0.79 to 0.826,
which leads to a decrease in the frequency of alternating modes of operation of thermal power plants
and, consequently, to a reduction in fuel consumption during the start-up of units, as well as the
accident rate of thermal equipment.
