Abstract：The hub traction substation(HTS) of electrified railway suffers from the problems such as frequent regenerative braking, large regenerative energy and low utilization rate. In this paper, the energy management and control strategy of regenerative braking energy(RBE) utilization system(RBEUS) combining energy feedback and energy storage are studied on the basis of the load characteristics of HTS. Firstly, the topology of RBEUS in HTS is analyzed as well as the operating principle. Aiming to maximize the utilization of RBE, an RBE distribution strategy was formulated based on the energy supply and demand relationship between the various parts of RBEUS. On the basis of that, the operating conditions of RBEUS were divided into four operating modes, and the energy flows of typical operating conditions were analyzed. Then, a hierarchical control strategy with a dynamic power allocation strategy was proposed. Finally, case studies were conducted to verify the correctness and validity of the above design. The results show that RBE can be transferred, fed back, stored, and released on demand with the proposed energy management and control strategy, and the efficient utilization of RBEUS in HTS can be realized.
