Abstract：Capacity allocation affects the operational feasibility and economic benefits of hybrid electric tram, which is the basic link in the design of hybrid electric system. Energy management strategy (EMS) and capacity allocation are coupled and influenced each other. Based on this characteristic, an improved convex (CVX) optimization algorithm for collaborative optimization of capacity allocation and energy management strategy is proposed. Firstly, the feasible region of capacity allocation is solved, and a family of equal weight lines is constructed in the feasible region. Under each equal weight line, the optimal group point of capacity allocation and EMS with minimum energy consumption is found. The dual-objective Pareto frontier of hybrid power system weight and energy consumption is obtained. Compared with the single energy storage system, the hybrid energy storage system is light in weight and small in volume. It is suitable for the situations with strict requirements on weight and volume. The simulation comparison shows that the EMS of collaborative optimization is efficient and the power distribution is reasonable.
