The invention discloses a network-source-storage-vehicle coordinated real-time energy management and control method for rail transit. The method comprises the following steps: firstly, collecting power information of each unit of a system in real time; judging the current working state and working mode of the system; and then, according to an operation mechanism of the'network-source-storage-vehicle 'cooperative power supply system, determining the reference power of the controllable quantity of each unit in the current working state and the working mode of the system, generating a corresponding power instruction, and adjusting the output power of the controllable quantity of each unit in real time. The core of the invention lies in a network-source-storage-train cooperative power supply system operation mechanism, in the power supply link, the train regenerative braking energy and new energy power generation system supplies power preferentially, then the energy storage system supplies power, and only when the train traction load requirement is still not met after the three power supply units supply power, the energy storage system supplies power preferentially. And in the electric energy consumption link, the energy storage system can consume redundant electric energy through charging only when the train traction load demand is met and the electric energy is still residual.
一种轨道交通“网‑源‑储‑车”协同的实时能源管控方法，先实时采集系统各单元功率信息；再判断系统当前工作状态以及工作模式；接着根据“网‑源‑储‑车”协同供电系统运行机制确定系统在当前工作状态以及工作模式下各单元可控量的参考功率，生成对应功率指令，实时调节各单元可控量的输出功率。本发明的核心在于“网‑源‑储‑车”协同供电系统运行机制，其在供电环节，列车再生制动能量与新能源发电系统优先供电，其次是储能系统供电，只有在该三个供电单元供电后，仍不满足列车牵引负荷需求时，才通过牵引变电所从电网获取电能，而在电能消纳环节，储能系统只有在列车牵引负荷需求被满足后电能仍有剩余的情况下，才会通过充电消纳多余电能。
