In the paper, the feasibility and application modes of Photovoltaic (PV) generation system were studied in Urban Rail Transit (URT). Firstly, the paper estimates the capacity of PV cells installation, and gets the results that PV generation system applied in the URT energy-savings is feasible by studying a typical elevated line of Shanghai URT. And then, in view of the particularity of URT power system and its loads, AC gridconnected mode and DC grid-connected mode are presented, and the grid-connected topology and energy management strategy were developed respectively. The results of simulation and theoretical analysis show that the AC grid-connected mode is simple and its control strategy is mature, but it hasn't energysavings amplification effect, DC grid-connected mode has energy-savings amplification effect, and can maximize the benefits of PV generation system through the optimization of control strategy. Finally, the key issues in the implementation of DC grid-connected mode were discussed.

“…Then, the stored energy can be reused by the passing trains when they need it (see Figure 9). The application of the wayside ESSs requires an electrical controller to distinguish the driving strategy of the nearby trains by detecting the voltage of the power line [27]. Trains in rail and rapid transit systems are usually braking near stations, and thus, the ESSs are normally installed near stations to increase the recovery efficiency.…”

Abstract:Increasing attention is being paid to the energy efficiency in metro systems to reduce the operational cost and to advocate the sustainability of railway systems. Classical research has studied the energy-efficient operational strategy and the energy-efficient system design separately to reduce the traction energy consumption. This paper aims to combine the operational strategies and the system design by analyzing how the infrastructure and vehicle parameters of metro systems influence the operational traction energy consumption. Firstly, a solution approach to the optimal train control model is introduced, which is used to design the Optimal Train Control Simulator(OTCS). Then, based on the OTCS, the performance of some important energy-efficient system design strategies is investigated to reduce the trains' traction energy consumption, including reduction of the train mass, improvement of the kinematic resistance, the design of the energy-saving gradient, increasing the maximum traction and braking forces, introducing regenerative braking and timetable optimization. As for these energy-efficient strategies, the performances are finally evaluated using the OTCS with the practical operational data of the Beijing Yizhuang metro line. The proposed approach gives an example to quantitatively analyze the energy reduction of different strategies in the system design procedure, which may help the decision makers to have an overview of the energy-efficient performances and then to make decisions by balancing the costs and the benefits.

“…A fixed energy storage system for DC electrified railways solves the problem of increasing energy costs by reducing primary energy consumption [2]. Without a fixed energy storage system, the energy generated by a braking vehicle would simply be converted into waste heat by its braking resistors if no other vehicles are powered simultaneously.…”
