“…In particular, the urban transportation infrastructure will show new interactions with electric power systems in response to the electrification of transportation. The effects of these interactions should be considered not only in EVs but also in electric railway [196,197] and light rail transit [198] systems, and therefore, comprehensive functions have to be evaluated considering the dynamic behavior of various urban infrastructures. One promising approach to understanding the dynamic behavior of urban infrastructures, where many elements interact in a complex way, would be cosimulation [199,200], which models the factors that exogenously affect multiple infrastructures and the physical elements that can affect each other.…”

Smart cities will be an important component for the construction of a sustainable future society. This paper focuses on the functionalities of smart cities from the perspective of electric power systems and reviews recent works on the various types of energy management systems (EMSs), particularly those focusing on the interaction among systems distributed in a city. Furthermore, this paper describes the idea of a platform for evaluating cooperative EMS technologies distributed in a city. The related research and demonstration of the EMS technology in real cities that were evaluated using the proposed platform are presented. © 2020 Institute of Electrical Engineers of Japan.

“…In [27], a coordinated approach of dynamically adjusting the load of the controllable rail train and energy storage battery is designed, which uses demand response decision of rail transits system with minimum operational energy. In [28], an integrated electricity-thermal EMS for high-speed railways is proposed, which uses two mode--train operation EMS and station operation EMS to control the power flow. In [29], a hierarchical model predictive control is designed, the energy consumption of the trains is controlled as a lower level and the energy flow of the whole TPSS is controlled as a higher level.…”

The Flexible Smart Traction Power Supply System and Its Hierarchical Energy Management Strategy

et al. 2021

With the increasing requirements of the railway sector for electrified railways and the development of society, the traction power supply system needs to become more flexible, economic and reliable. The traditional traction power supply system has many problems due to its own topology, such as negative sequence current, load fluctuation, low utilization rate of regenerative braking energy, and inability to use the distributed generation along the railway. In order to solve these problems and make the traction power supply system (TPSS) more flexible, efficient and reliable, a novel TPSS called flexible smart traction power supply system (FSTPSS) is proposed. This traction power supply system consists of AC-DC-AC traction substation and the microgrid along the railway. It can effectively mitigate the problems of negative sequence current, improve regenerative braking energy utilization and distributed generation utilization. A hierarchical energy management strategy is also proposed here, which can effectively improve the operating economy of FSTPSS and reduce the load fluctuation of FSTPSS. And based on the actual load measurement power of a traction substation of China's Beijing-Shanghai high-speed railway, the proposed energy management strategy has been verified for the economic improvement and load fluctuation reduction of TPSS.

“…Aguado et al [14] proposed a methodology for optimal operation planning of railway energy systems considering the uncertainties associated with RES through scenario tree approach. Novak et al [15] presented a hierarchical coordination scheme for substation energy flow control and the individual traction control, and used a stationary ESS to minimise energy consumption. Through interactions with other power systems, the ERS is transformed from a passive energy consumer into a proactive system which has the capability to respond to various grid demands.…”
