Abstract

Abstract: The electric vehicle （EV） charging-swapping-storage integrated station （CSSIS） is an electric vehicle centralized integrated energy storage and power station that integrates charging stations， power conversion stations and cascade energy storage power stations， which can reduce system power fluctuations. This paper proposes a model of electric vehicle CSSIS considering fast charging station， battery swapping station and cascade energy storage station. Firstly， according to the behavior characteristics of fast-charging users， a model of EV fast charging station is established. Secondly， on the basis of speed-flow practical model of city roads， a model of EV battery swapping station is established. Finally， combined with the cascade energy storage model， an integrated electric vehicle CSSIS model is constructed. Taking the actual road conditions of bus lines in a city into account， a case verifies that the integrated station model proposed in this paper can meet the demand of electric vehicle charging load， and has the advantages of reducing the daily total operation cost and suppressing power fluctuation.

Key words: electric vehicle charging-swapping-storage integrated station, fast-charging users, speed-flow model, actual road condition
