An Algorithm for Determining the Calculated Electrical Loads of Electric Vehicles Charging Stations

The study is devoted to the analysis of factors affecting the power consumption of electric charging infrastructure facilities, as well as the development of an algorithm for determining the calculated electrical loads of electric vehicle charging stations. The article presents the results of an analytical review of research in the field of determining the calculated electrical loads of electric vehicle charging stations, and compares the results obtained by different authors with the identification of the main influencing factors. To study electrical loads, a simulation model has been developed that makes it possible to simulate minute-by-minute power consumption profiles with specified parameters of electric charging stations and electric vehicles, including taking into account the charging behavior of electric vehicle owners. A quantitative assessment of the importance of the factors influencing the demand coefficient of the electric charging infrastructure of electric transport has been carried out. An expression is proposed and an algorithm is developed for determining the calculated electrical loads of homogeneous and heterogeneous groups of electric vehicles charging stations.
