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].

Does the ESS provide its own energy to the tram?

Conversely, if the increase of E reg is less than the reduction of energy from E sub, then the ESS provides its own energy to the tram.

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.

Can EVs be used as energy storage for the tram network?

Therefore, this research assumes that the tram service provider would provide the EV owners, who allow their EVs to be used as energy storage for the tram network, with incentives (e.g. discounted travel perhaps) to compensate for the extra degradation of the EV battery.

Does a tramway consume energy?

In the coasting condition stage, the tramway does not consume energy. In the braking condition stage, the tramway will feedback part of the braking energy for storage. The total energy consumption is the sum of traction energy consumption minus regenerative braking energy during operation.

What is the energy consumption optimization model of tramway operation?

Energy consumption optimization of tramway operation is significant in reducing the operation cost. Therefore, the energy consumption optimization model of tramway operation based on the improved PSO algorithm is developed. Firstly, the energy consumption model of the tramway is established based on the energy-saving operation strategy.
