Charging stations for electric cars using hybrid energy storage systems

Abstract

Abstract In this article, it is proposed to use energy storage devices as a part of charging stations to reduce the powerful load for the power system during the hours of the greatest energy consumption. This is due to the analysis results for the growth trends of the electric vehicles. By the example of the city Novosibirsk, according to the forecasts of analytical companies about the trend of increasing the number of electric cars (ECs) in Russia, the average energy consumption per day for charging ECs has been calculated. Based on the calculation results, the influence of charging stations on the daily schedule of the active load for the industrial power grid is shown and the capacity lack problem is identified. The experimental measurements results at traction substation No. 29 in Novosibirsk are presented.
