Energy storage system analysis for heavy haul hybrid locomotives

Based on the longitudinal heavy haul train simulation results on two typical track routes in Australia, the train energy usages and the energy from dynamic braking are analysed. It is found that there is high potential for hybrid heavy haul locomotive applications. The methods have been put forward in order to realise the applications. Sizing the energy storage system (ESS) with batteries and supercapacitors has been carried out respectively. The problems with their applications have been discussed.
