Abstract

Energy management strategy (EMS) and sizing are the key steps in the design of a tram’s power system and the result has a direct influence on the operation characteristics and economic benefit. This paper proposed an improved EMS with energy interaction and made collaborative sizing optimization based on actual vehicle and line conditions. The superiority of the improved EMS was shown through the sizing result and was verified on the experiment platform at the same time. Simulation and experiment showed that the improved EMS reduced the weight of hybrid storage system and guaranteed the normal operation even at emergency.
