The increasing expansion of the electric rail transport network around the world on the one hand and the rising price of electricity on the other hand pro‎mp‎ted researchers to research ways to reduce energy consumption in these systems. In this regard, one of the ways to reduce energy consumption in the electric rail transport network is to use recycled energy from the brakes. In the braking process, the train returns energy to the grid, which can be reused if stored by storage systems. The energy stored in the storage system can be used at another time, such as acceleration time. The use of storage in addition to reducing energy consumption due to the use of brake reproduction energy, also stabilizes the mains voltage and reduces peak consumption. In this project, a hybrid storage system of fuel cell type, supercapacitor and battery for trams with hypothetical load It is considered that the energy management of these three systems is possible through the control of DC-DC converters connected to them. After proving the stability, the desired output is received and then the nonlinear predictive controller is proposed for energy management in the mentioned system and the outputs are compared with the nonlinear feedback controller. PSO is used for optimization in the control method and energy management through the nonlinear predictive control method gives good results compared to the nonlinear feedback controller.
