| Popis: | New trends in the fight against climate change on the planet, suggesting a reduction in greenhouse gas emissions, are influencing the formation of a new structure of the electric power system. As the experience of the European Union shows, the active development of renewable energy sources affects the electrical modes of operation of power plants and in the future can lead to a decrease in electricity production in a highly efficient combined generation mode at CHPPs. Thus, there is an acute issue of finding a place for a CHP plant in the emerging power systems, in which generating equipment will be especially in demand, effectively operating in half-peak and peak modes to cover the daily load unevenness. The development and commissioning of a highly maneuverable GTU-CHPP, capable of operating in a combined generation mode with daily starts / stops, can significantly increase the efficiency of electricity generation in the peak part of the daily load schedule. The system effect of the commisionning of 10 GW of highly maneuverable GtU-CHPPs within the UES of Russia will reduce the consumption of fossil fuel by 19.6 million tce per year and CO2 and NOx emissions by 55 million tons and 24.7 thousand tons per year, respectively. |
