Wellington tram energy storage

Why are trams with energy storage important?

Trams with energy storage are popular for their energy efficiency and reduced operational risk. An effective energy management strategy is optimized to enable a reasonable distribution of demand power among the storage elements, efficient use of energy as well as enhance the service life of the hybrid energy storage system (HESS).

How energy management strategy is used in Guangzhou Haizhu trams?

An improved PSO algorithm based on competitive mechanism is developed to obtain the optimal energy management strategy. The obtained energy management strategy has better effects in energy reduction with application in Guangzhou Haizhu tram. Trams with energy storage are popular for their energy efficiency and reduced operational risk.

How to save energy in rail transportation?

For energy saving and emission reduction in rail transportation, the development of fuel cell electric locomotives based on renewable and clean energy, power locomotives using power batteries, and new locomotives based on various hybrid power have become new technologies and ways [ 1, 2 ].

How do energy storage elements work?

Under the optimal discharge current corresponding to the power threshold value, the energy storage element works according to the two energy management strategies, and the electrical quantity change curve is obtained, as shown in Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10.
