Can subway transfer stations store energy

Why do subway stations use a lot of electricity?

The VAC and lighting systems dominate the subway stations’ electricity consumption. Influencing factors have also been preliminarily investigated. Subway transportation systems are in rapid development and energy consumption in subway stations is becoming more and more significant.

Do subway stations affect energy consumption?

Hong and Kim (2004) have revealed the energy consumption level of subway stations in four Korean cities and the climatic effect on energy consumption has been briefed, however, energy consumption of main subsystems in these stations hasn’t been separated and discussed.

How much electricity does a subway station use?

Energy audit of 341 subway stations in 5 Chinese cities are conducted. An underground non-transfer station consumes 1.8–2.3 million kWh/year averagely. The VAC and lighting systems dominate the subway stations’ electricity consumption. Influencing factors have also been preliminarily investigated.

Does the subway system save energy?

As for the subway system, abundant studies have paid close attention to the energy consumption of rolling stock and corresponding measures for its energy saving ( Ghoseiri, Szidarovszky, & Asgharpour, 2004; Lin, Li, Zhao, & Yang, 2016; Ye & Liu, 2016 ).

Do crowded underground non-transfer stations improve energy consumption performance?

The most crowded stations in City A and City D appear to show a better energy consumption performance from the perspective of passenger flow, which may bring about misunderstanding and misdirection. Fig. 6. Annual consumption per unit floor area of underground non-transfer stations in 5 cities.

How much energy does an underground non-transfer station consume?

The main conclusions could be summarized as following. An underground non-transfer station consumes 1.8–2.0 million kWh/year averaged in Cities A–D, whereas 2.3 million kWh/year in City E located in the hot summer and warm winter zone with a cooling season more than 7 months.
