Abstract
Purpose:The aim of the study is to evaluate the efficiency of using conventional energy facilities based on renewable energy sources to provide energy to battery swapping stations and charging stations for electric vehicles in one of the selected countries.As part of the work, the following tasks are solved: A mathematical model of charging stations or battery swapping stations, electrical installations based on renewable energy, and general energy facilities operating parallel to the electrical grid and autonomously is developed; A methodology has been developed, verifying the structures and parameters of energy facilities based on renewable energy sources for charging batteries of electric vehicles; The efficiency of using generation facilities based on renewable energy sources to battery charging stations in rural areas of such a large country is evaluated; The number of hybrid energy facilities based on renewable energy sources and charging stations is evaluated.Design/methodology/approach: The examined power plant facilities serve electric vehicles in cities, recreation areas, industrial enterprises, and highways.Service types such as charging the battery and replacing discharged batteries of electric vehicles with pre-charged batteries are used at charging stations for electric vehicles.The efficiency of using conventional energy installations as part of charging stations is evaluated in regions with different climatic conditions.Findings: The results show an increase in profit when participating in the ancillary service market.Originality/value: In the following research paper were presented the optimization objective function that maximizes the profit.
