Abstract

Abstract: With the rapid construction of the energy internet, there will be increasing penetration of such mobile loads as electric vehicles, and fast charging stations (FCS) will operate in large-scale. As a result, the power grid is facing increasing controlling difficulties and instability risks because of its complex network structure and multi-agent regulation modes. Based on an investigation of the recent researches both at home and abroad on the influence factors of FCS grid-connection and the performance of involved grids, we focus on analyzing the three main challenges of large-scaled FCS to the grid. In addition, according to the novel application modes of "FCS+energy storage system (ESS)+other elements" in the energy internet, we also analyze the existing research progress and engineering experience in this field through a case study of integrated PV-storage-charging stations, and make a comparison of the similarities and differences between the large-scaled FCS and the integrated charging-storage/PV-storage-charging stations. Finally, from the perspectives of application prospect and key technologies, the future development of FCS with ESS is discussed.

Key words: energy storage, fast charging station, charging and storage integration, electric vehicle, control technology
