Abstract

The co-phase traction power supply system (TPSS) with hybrid energy storage system (HESS) and photovoltaic (PV) is proposed to eliminate the neutral section and improve the regenerative braking energy (RBE) utilization. Although the integration of HESS and PV facilitates the energy saving and cost reduction of the co-phase TPSS, the high cost and configuration of HESS should be considered, which is the key to affect the optimal operation strategy of co-phase TPSS. Here, the optimal operation strategy of co-phase TPSS with HESS and PV is proposed to design the HESS configuration, recycle RBE and improve power quality. The proposed model aims to minimize the total system cost, including HESS investment cost, electricity cost and operation and maintenance cost. Moreover, the proposed model is formulated as a mixed integer linear programming by employing linearization approaches. Finally, case studies verify that the 29.2% cost reduction rate is achieved and the three-phase voltage unbalance meets the standard requirements.

带 HESS 和光伏的同相牵引供电系统的优化运行

为了消除中性段并提高再生制动能量（RBE）的利用率，提出了带有混合储能系统（HESS）和光伏（PV）的同相牵引供电系统（TPSS）。虽然 HESS 与光伏的集成有利于同相 TPSS 的节能和降低成本，但应考虑 HESS 的高成本和配置，这是影响同相 TPSS 优化运行策略的关键。本文提出了 HESS 与光伏共相 TPSS 的优化运行策略，以设计 HESS 配置、回收 RBE 并改善电能质量。提出的模型旨在最大限度地降低系统总成本，包括 HESS 投资成本、电力成本和运行维护成本。此外，还采用线性化方法将所提模型表述为混合整数线性规划。最后，案例研究验证了成本降低率达到了 29.2%，三相电压不平衡符合标准要求。
