With the development of the social economy and the demand for environmental protection, people's requirements for clean and renewable energy are gradually increasing. Generally, renewable energy, such as win. With the development of the social economy, people's demand for electricity and energy is. 2.1. Study area and data collectionThe research object of this study is the Jinshuitan Reservoir in Lishui city, Zhejiang Province, which is located on the Longquan Stream, a tributar. 3.1. Water temperature structure without pumpingBased on the simulation results, it can be seen that the Jinshuitan Reservoir is a water temperatur. 4.1. Sensitivity analysisThe previous two sections introduced the distribution characteristics of water temperature in the reservoir area under different outlet el. There are significant differences in the reservoir water temperature distribution between mixed pumped storage power stations and conventional power stations. This paper studie.

What are the operation characteristics of a pumped storage power station?
The operation characteristics of a pumped storage power station are as follows: water is released to generate electricity in peak-demand periods, and water is pumped to store energy in low-demand periods, resulting in great differences in thermal and dynamic factors.
Do pumped storage power stations have a water temperature structure?
However, there are few studies on the water temperature structure and its influencing factors associated with this type of pumped storage power station. The combination of prototype observations and numerical simulations is becoming increasingly important in the study of reservoir water temperature structures.
Are pumped storage power stations different from conventional power stations?
There are significant differences in the water temperature distribution between the reservoirs of pumped storage power stations and those of conventional power stations.
What is pumped storage hydropower (PSH)?
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
How does a mixed pumped storage power station affect water temperature?
The construction of a reservoir inevitably changes the water temperature situation of the original river channel. The expansion of pumping and storage units on a pre-existing reservoir, namely, a mixed pumped storage power station, is different from a conventional power station in terms of the thermal structure of the reservoir area.
What are the different types of pumped storage power stations?
Pumped storage power stations can be divided into two types according to the construction type and whether there is natural inflow. One is pure pumped storage power stations, in which the upper reservoir has no natural inflow, and the upper and lower reservoirs form an independent system.
