Energy Efficiency Optimization of Collaborative Power Supply System with Supercapacitor Storages

To solve the challenge of low efficiency and high operation cost caused by intermittent high-power charging in an energy storage tram, this work presents a collaborative power supply system with supercapacitor storage. The scheme can reduce peak transformer, therefore reducing grid-side capacity improving efficiency. However, there is lack quantitative analysis on performance improvement solution. models critical components are proposed to evaluate system, optimization conducted. Taking operational tram line as example, improved reduced operating costs derived. Further, ground designed implemented. measured data demonstrates that optimized improved, which proves its effectiveness practicability.
