Evaluation of energy and resource saving effect at implementation of hybrid objects of small distributed generation in the republic of Vietnam

Abstract

The work presents the main characteristics of the most efficient solar energy technologies, including in small distributed energy. The use of hybrid technologies based on the use of solar radiation is justified. The prospects of these facilities in one of the provinces of the Republic of Viet Nam (Ninh Tuan), which is characterized by the highest intensity of solar radiation, have been determined. The results of calculation of the station with capacity of 4.6 MW, operating on the basis of use of GTU without use of solar energy and its use for heating of air entering the combustion chamber, are presented. The energy-saving effect of the introduction of hybrid technologies is due to the increase in the efficiency of the station by 6% to 10% depending on the time of year and the characteristic intensity of solar radiation and ambient temperature. A significant decrease in the consumption of fuel (natural gas) used in the gas turbine plant has been detected.
