EV''s as energy storage on urban light rail systems — A synergy of …
The use of urban light rail networks to provide charging of EV''s at locations within a city, and the use of the EV''s as trackside energy storage to capture regenerated energy from trams leads to a win–win scenario, increasing the availability of EV charging, whilst improving the efficiency of the urban light trail systems.
Stochastic optimization of a stationary energy storage system …
Compared with traditional tram powered by a DC catenary, energy efficiency of the catenary-free tram can be enhanced considerably due to increased recuperation of braking energy [4], [5]. For traditional tramlines, the regenerative energy of the trams is not stored, but rather immediately delivered to adjacent trams that are in an …
Simulation model of tram with energy storage system
The paper is concerned with description of the simulation model of the tram equipped by the energy storage system using supercapacitors. This paper is also concerned with the construction of the tram emulation with the energy storage system. The tram accumulates the kinetic energy into supercapacitors during vehicle braking. This energy can be used …
Optimal Sizing of On-Board Energy Storage Systems and …
This paper introduces an optimal sizing method for a catenary-free tram, in which both on-board energy storage systems and charging infrastructures are considered. To quantitatively analyze the trade-off between available charging time and economic operation, a daily cost function containing a whole life-time cost of energy …

Energy efficiency of tram emulation with energy storage system
The paper is concerned with construction of the energy efficiency measurement of the tram emulation with the energy storage system. The kinetic energy is accumulated into the supercapacitor during vehicle braking. This energy can be used to accelerate the tram (in next). It is important to save the braking energy of the vehicle, which accelerate very often.
Energy management strategy optimization for hybrid energy storage ...
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). …
Energy management strategy optimization for hybrid energy storage ...
The characteristics of the energy storage equipment of the tram, which is the tram power supply system, will largely affect the performance of the whole vehicle. Since there is still a lack of a single energy storage element with high power density and energy density to meet the vehicle operation requirements [6, 7]. A common solution for on ...
Research on Sizing Method of Tram Vehicle Hybrid Energy Storage System …
In order to design a well-performing hybrid storage system for trams, optimization of energy management strategy (EMS) and sizing is crucial. This paper establishes a mathematical model of battery and supercapacitor, compares the topology used in trams. Using adaptive particle swarm optimization(PSO) to optimize the size of battery and …
Supercapacitor and accelerating contact lines hybrid tram system
A supercapacitor and accelerating contact line hybrid tram system is proposed. •. A tram consumes high energy during acceleration but, low energy thereafter. •. Supercapacitors can be charged fast but, they have low energy density. •. During acceleration, a tram draws power from accelerating contact line. •.
Optimal sizing of battery-supercapacitor energy storage systems …
A hybrid energy storage system (HESS) of tram composed of different energy storage elements (ESEs) is gradually being adopted, leveraging the advantages of each ESE. The optimal sizing of HESS with a reasonable combination of different ESEs has become an important issue in improving energy management efficiency. Therefore, the optimal …
