The relevance of the work is caused by the intensive economic development of the countries of Northeast Asia, the increase in their electricity demand and feasibility of improving the economic and environmental efficiency of electricity supply through the implementation of electrical energy integration projects. In this case, the large-scale introduction of renewable energy sources can play an important role. The aim of the research is to determine the optimal structure of wind power plants in the Mongolian part of the Gobi Desert (the ratio of the capacities of different types of power plants and their generation of electricity) for different combinations of economic and climatic conditions. Methods: systematization of climatic and meteorological information, preliminary assessment of the effectiveness of energy sources of various types according to the criterion of the cost of electricity produced, mathematical modeling of the structure and modes of operation of the power system. The mathematical model takes into account the random nature of solar and wind energy. Results. It is shown that the electricity produced by photoelectric converters and wind turbines, taking into account the cost of its transport along power transmission lines, is competitive in the electricity markets of China and other countries of Northeast Asia. For various values of solar radiation input and wind speed, the optimum ratios were determined between the capacities of renewable energy sources, the production of electricity by photoelectric converters and wind turbines, as well as the supply of electricity from China’s power system to compensate the unevenness in production of renewable energy sources. The economic efficiency of joint use of solar and wind energy in the Mongolian part of the Gobi desert is shown, with the exception of some areas with low wind speeds. The combined use of solar and wind energy allows reducing the total costs in the power supply system by more than a quarter compared with the variant of using only solar energy. © 2020 Tomsk Polytechnic University, Publishing House.
