DC Microgrid Topologies and Stability Analysis for Electrified Transportation Systems

In this paper, the topology of dc microgrid implemented in electrified transportation systems is studied. Due to the commonly used topology is not entirely realistic, to solve this problem, this paper presents three different topologies that correspond to three kinds of dc microgrid structures in practice. Moreover, modeling and stability analysis are developed to define the stability characteristics in each case. The simulation results are performed to confirm the correctness of the proposed topology and the accuracy of the modeling and stability analysis.
