“…Practical employments of storage units can be either stationary or mobile [3][4][5]. In the first case, they can be used to reduce the energy demand of the whole system and to stabilize the supply network voltage at weak points (e.g., the voltage drops typically associated with end of lines) with the potential elimination of additional feeding substations [6].…”

Abstract:The growing interest in the use of energy storage systems to improve the performance of tramways has prompted the development of control techniques and optimal storage devices, displacement, and sizing to obtain the maximum profit and reduce the total installation cost. Recently, the rapid diffusion of renewable energy generation from photovoltaic panels has also created a large interest in coupling renewable energy and storage units. This study analyzed the integration of a photovoltaic power plant, supercapacitor energy storage system, and railway power system. Random optimization was used to verify the feasibility of this integration in a real tramway electric system operating in the city of Naples, and the benefits and total cost of this integration were evaluated.

“…The ESS stores energy using storage devices with good power density and a high number of cycles, such as an electric double-layer capacitor (EDLC), flywheels and superconducting magnetic energy storage (SMES) [11]. The ESS can be either installed onboard the vehicle [6,10,16,17] or installed at the substation level or along the track [8][9][10][11][12][13][14][15]. In the former case, the ESS is called the onboard ESS, which is used to recover the braking energy and to smooth the electric power peak of hybrid vehicles.…”

In 2014, more than 43 cities in China were racing to construct their urban rail systems (including metro and light rail systems), recognizing that an urban rail system will be a good solution to the tough problems that they are faced with, including traffic congestion and PM2.5 air pollution. On 22 August 2012, the first electric double-layer capacitor (EDLC) energy storage-type rail vehicle in the world was unveiled at Zhuzhou Electric Locomotive Co., China. The EDLC rail system has been considered a promising sustainable urban rail system, which is expected to further improve the energy efficiency and to reduce environmental pollution. The first commercial EDLC tram produced by Zhuzhou Electric Locomotive Co. has been applied at Guangzhou Metro Corp. recently. From the view point of scientific research, the system design and energy management of EDLC rail systems have been extensively studied in the literature, while the stationary charging station design for the EDLC energy storage-type urban rail vehicles has been rarely reported. Thus, the aim of this paper is to report a stationary charging station that has been successfully applied in the EDLC rail system produced by Zhuzhou Electric Locomotive Co., China.

“…Most of them are sized for d = 0.5 [3][4][5][6][7], which is recommended by SC manufacturers and gives the maximum available useful energy (75% of the energy stored in an SC). This value of d is chosen taking into account only the energy requirements.…”

The paper considers the problem of choosing the optimum size for on-board energy storage system (ESS) based on supercapacitors (SCs) taking into account both the braking energy and the braking power of an electrical vehicle. The authors have derived equations for calculation of the minimum SC number in the bank and the optimum depth of its discharge. The theory is exemplified by the Škoda 24Tr trolleybus. Besides, by simulation of the ESS mathematical model, the dependence of the saved braking energy vs. SC number at the optimum discharge depth has been studied. The research shows that a reduced number of SCs may be used as compromise solution between the ESS efficiency and its cost. It was found that in most cases the optimum discharge depth is much higher than 0.5 − the value recommended by SC manufacturers and often met in literature.
