Tram distributed energy storage policy

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).

Can a tram's driving strategy reduce energy consumption and extend battery life?

However, trams may face expensive battery replacement costs due to battery degradation. Therefore, this paper proposes a multi-objective optimization method for the tram's driving strategy to reduce operational energy consumption and extend battery life. The method describes the optimization problem as second-order cone programming (SOCP).

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 reduce the energy consumption of trams?

As tram utilization increases, the operational energy consumption of the tram system grows. Therefore, it is crucial to save energy and reduce the energy consumption of trams. One promising approach is to optimize the speed trajectory of the tram, also known as energy-efficient driving [1, 2].

How does a tram work?

The tram mainly comprises the energy storage system, traction system, and auxiliary system, and the specific structure is shown in Fig. 1. As the sole power source of the tram, the battery pack can supply power to the traction system and absorb the regenerative braking energy during electric braking to recharge the energy storage system.

How to optimize the driving strategy for a tram?

In recent years, optimizing the driving strategy for the tram has become a research hotspot. However, the existing driving strategy optimization often focuses only on energy saving while ignoring the possible adverse effects of the driving strategy on the battery life.
