Current management for charging stations with power coupling items and three charging modes of electric vehicles under DoS attacks

Abstract

Although the electric vehicle supplied through distributed generators (DGs) as one of the most important methods to reduce carbon emissions has become a research hotspot, the current management for charging stations with power coupling items and three charging modes of electric vehicles under denial of service (DoS) attacks, is rarely studied. Based on this, this paper proposes a new fully distributed consensus fuzzy control to achieve accurate current sharing for charging stations with power coupling items and three charging modes of electric vehicles under DoS attacks. Firstly, the system regarding charging stations with power coupling items and three charging modes is modeled which lays the foundation for the next design. Next, DoS attacks as the common network attacks are taken into consideration and modeled. Meanwhile, in order to reduce the communication burden, the fuzzy logic controller (FLC) is designed in this paper. Then the fully distributed consensus fuzzy control considered DoS attacks is proposed to achieve the current sharing control accurately for charging stations with power items and three charging modes under DoS attacks. Moreover, the system under the distributed consensus fuzzy control strategy is discussed in different situations. Finally, simulation comparisons and experiment results are carried out to verify the performance of the proposed control strategy.
