Abstract
Economic efficiency assessment of an autonomous power supply system with renewable energy sources on Lake Baikal coast has been carried out. The system includes photovoltaic converters, wind turbines, storage batteries and a diesel power plant. The optimal modes of operation of the system elements and its structure have been determined. For this purpose, a mathematical model is used that minimizes the total discounted costs while meeting a number of constraints. Climatic and meteorological data correspond to the conditions of the areas of the Lake Baikal coast in the Irkutsk region, not connected to a centralized power supply. The energy generated by renewable energy sources has been determined. The calculation results showed that the joint use of solar and wind energy increases the economic efficiency of the power system: the rejection of one of these energy sources increases costs.
