A multi-source hybrid power generation system technology based on fuel cell system cluster is one of the research frontiers of new energy application in rail transit domain. In this project, due to the existence of the severe problems of the declining health state of fuel cell system cluster, the multi-index robust optimization constraints and inconsistent parallel operating states of multi-source hybrid power generation system with uncertain under complex traction conditions and different marshalling ways, a coordination control method of multi-marshalling and multi-source hybrid power generation system based on health state evaluation of fuel cell system cluster is proposed for hybrid power tramway by investigating the characteristics of fuel cell system cluster, the multi-index robust feasibility constraints and the uniform convergence characteristics of multi-source hybrid power generation system. The proposed method is able to synthetically take into account the interactive influence of uncertainty parameter perturbation on the equivalent hydrogen consumption, dynamic performance and useful life of fuel cell system cluster, and achieve to improve system energy efficiency and prolong the full life cycles of different power sources, and then guarantees reliable and efficient operation for the whole system. The research of this project will provide theoretical and technological support for developing the efficient and environmental multi-source hybrid power generation system based on fuel cell system cluster access for the hybrid power tramway.
