This paper presents the best Energy Management Strategy (EMS) presented to the IEEE VTS motor vehicleschallenge 2019 - Energy Management of a dual-mode locomotive. The proposed solution aims to minimize the consumption of electricity and hydrogen; and to increase the lifetime of the fuel cell and energy storage system in a dual mode locomotive. The proposed EMS is based on rules that consider the energy and power densities of the energy sources. The paper proposes a global EMS, local EMS for each source and simulation results for four different speed and power profiles.
