Abstract: Diesel power plant is one of the most common components of autonomous hybrid complexes based on renewable energy sources. The main parameter of a diesel power plant is fuel consumption, the value of which affects directly the operating costs, as well as indirectly on the optimal values of installed capacity of other components of the hybrid complex. The typical approach to the calculation of diesel fuel consumption, which is used in most scientific works does not take into account the influence of the nominal capacity of diesel-generator sets on the specific fuel consumption. In this paper the life cycle of a diesel power plant in the composition of an autonomous hybrid complex with a wind turbine is evaluated. The author's model of calculation of diesel fuel consumption taking into account technical (passport) data of diesel-generator units and their current load in the diesel power plant is proposed. On the basis of the wind speed reanalysis data and real load data of Gyda settlement (Yamalo-Nenets Autonomous District) simulation modeling is carried out, according to the results of which the divergence of results between the author's and typical models is determined, which at long time intervals leads to a significant difference in the economic evaluation of the complex operation.
