1. Introduction
URT has become the preferred solution to solve traffic congestion in large and medium-sized cities in China because of being fast, safe, punctual, and having a large passenger capacity [1,2]. However, it is also a huge energy consumer. In Shanghai, the annual energy consumption of URT is more than 1.9 billion kWh. The energy conservation problem is becoming increasingly prominent [3]. As a kind of renewable energy, PV power generation has no pollution and no noise, and it is convenient and flexible to install [4], which has been widely used in many fields [5,6]. A number of studies have been carried out on PV plants [7], PV grid connection systems and control strategy [8,9]. It is very attractive to install PV panels in URT system. The future development of URT urgently needs the introduction of this green, sustainable and low-carbon technology. There have been already some demonstrative projects in URT. Singapore has installed 1 MW of PV system on the roof of metro depots, which can reduce carbon emissions by 500 tons per year. The Belgian Railway Company has built a 3KM long PV tunnel with a power capacity of 3 MW. Indian Railways installed PV modules on the roof of trains to provide ventilation, lighting, and air conditioning [10]. Japan’s JR Railway Company installed a 453KW PV unit on the roof of the Tokyo platform, which is expected to generate 340MWh of electricity per year and reduce carbon emissions by 101 tons [11]. Shanghai Shentong Metro Company also started construction of PV roof for 6.8 MW vehicle segment [12].
