High-speed rail stations have solar power generation

Should solar PV be introduced into the railway energy supply system?

Solar PV generation is concentrated in the daytime period, matching the railway load, so it is appropriate to introduce solar PV generation into the railway’s energy supply system (IEA,2019). Therefore, a series of railway system transformations are needed to fully exploit this advantage.

Why is solar-powered rail transportation a good option?

Although the total cost of the solar-powered rail transportation is relatively high, it can make full use of the rail own land with no increasing land for solar panel installations. Furthermore, due to the rail energy consumption, this approach facilitates the solar energy accommodation with less curtailment.

Can photovoltaic power high-speed bullet trains?

Application of the existing infrastructures of railway stations and available land along rail lines for photovoltaic (PV) electricity generation has the potential to power high-speed bullet trains with renewable energy and supply surplus electricity to surrounding users.

Can distributed photovoltaic generation and energy storage systems be used in high-speed railways?

Zhiming et al. study the optimal planning of distributed photovoltaic generation (DPVG) and energy storage systems (ESSs) for the traction power supply system (TPSS) of the high-speed railway. This lecture demonstrates the potential and applicability of DPVG and ESS to the high-speed railway industry [ 7 ].

Which railway stations are underexploited by solar power?

The Beijingnan Railway Station, the first large-scale railway station in China to use solar power, is also underexploited in terms of its PV potential. This station has installed 3264 solar panels thus far, with a total power of merely 245 kW. A similar problem occurs at the Shanghai Hongqiao Station. The PV potential of the BS-HSR is very high.

Can solar energy be used in the rail sector?

These initial field trials demonstrate that the usage of the solar energy generation in the rail sector has a strong potential with the technological progress and cost reduction in the future. As seen, it is forecasted that the solar energy would play a vital role in the rail sector for renewable power supply and carbon emission reduction.
