Research on water transfer and energy storage scheme

Does Water Transfer Scheme 2 reduce the impact of inter-basin water transfer?

Through quantitative analysis, we found that compared to water transfer Scheme 1, water transfer Scheme 2 can reduce the impact of inter-basin water transfer on the power generation of the cascade reservoirs of the Yangtze River mainstream, thus reducing the risk of insufficient power supply during the dry season.

Will Water Transfer Scheme 1 aggravate the problem of insufficient power supply?

Since the power generation during the dry season is already insufficient, water transfer Scheme 1 would aggravate the problem of insufficient power supply during the dry season of the Yangtze River mainstem. Table 6.

What is Water Transfer Scheme 2?

Water transfer Scheme 2 involves distributing the annual water transfer amount evenly across each month, under the premise of a constant total water transfer amount, in order to achieve a balanced and stable water transfer, and minimize construction costs.

Does Scheme 2 reduce the loss of hydropower generation?

Comparing two inter-basin water transfer schemes, Scheme 2 was found to reduce the loss of hydropower generation in the Yangtze River cascade hydropower stations without decreasing the total amount of water transferred. Compared to Scheme 1, Scheme 2 could reduce the loss of hydropower generation by 1.38 billion kilowatt-hours.

Do Water Transfer schemes reduce pressure on groundwater resources?

While it has been shown that water transfer schemes can reduce the pressure on groundwater resources (Poland, 1981), improve water quality (Hu et al., 2008; Rivera-Monroy et al., 2013), and support ecosystem restoration measures (Snedden et al., 2007; Dadaser-Celik et al., 2009); there are concerns about their impacts.

How aquifer thermal energy storage system works?

Aquifer thermal energy storage system The idea of deliberate storage of heat and cold in aquifers, can be traced back to the mid-1960s (Fleuchaus et al., 2018) in China, where the cold water would injected into aquifers in order to rectify the subsidence problem.
