The impact of pumped storage power stations on thermal power

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 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.

How to optimize pumped-storage power station operation?

Propose a novel optimization framework of pumped-storage power station operation. Optimize pumped-storage power station operation considering renewable energy inputs. GOA optimizes peak-shaving and valley-filling operation of pumped-storage power station. Promote synergies of hydropower output, power benefit, and CO 2 emission reduction.

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.

Can pumped storage power stations save energy?

As a mature, economic and large-scale energy storage technique, the storage of energy by pumped storage power stations is notable [ 9, 10 ]. The development of pumped storage power stations can effectively store excess power, coordinate and complement other energy sources, and avoid resource waste.

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.
