| Summary: | To smooth the fluctuation of voltage and power in traction grid of urban rail transit system, various energy feedback units and energy storage devices are placed in the actual system. Consequently, violent fluctuation is relieved and losses on braking resistors have reduced. Accompanied by the popularity of electric vehicles (EVs) and development of vehicle-to-grid (V2G) technology, fluctuation of renewable energy can be reduced and stability of city grid can be improved, meanwhile the owners of EVs can also get profits. In this paper, a novel architecture integrating EVs with urban rail transit was put forward, which can absorb feedback braking energy of train and bring profits. By applying power electronics transformer (PET) on the V2G converter which comprises of a cascaded topology of LLC series resonant converter, higher safety and smaller volume are realized while electrical isolation is achieved. Simulation results verified the feasibility and validity of the architecture. |
