At present, the utilization of the pumped storage is the main scheme to solve the problem of nuclear power stability, such as peak shaving, frequency regulation and active power control [7]. [8] has proved that the joint operation of nuclear power station and pumped storage power station can peak shave more flexibly and economically.
Pumped storage power stations have excellent characteristics such as fast start and stop speed, rapid load increase and decrease speed, and low forced outage
One possible solution for such a problem is to utilise large-scale energy storage such as pumped-hydroelectric, compressed air, or Hydrogen storage.

With higher needs for storage and grid support services, Pumped Hydro Storage is the natural large-scale energy storage solution. It provides all services from reactive power support to frequency control, synchronous or virtual inertia and black-start capabilities. It brings support that was previously managed by fossil-fueled power plants but
While Guangdong Pumped Storage Power Station has a capacity of 2.4 GW, Huizhou has a slightly larger capacity of 2.448 GW. The increased number of turbines might mean more machinery to maintain and operate, but also offers the plants greater flexibility in how much electricity they absorb and generate. 4.
The proposed BB pumped-storage power station will play an important role in helping to meet the peak shaving demand of the HH power system around 2030. The BB pumped storage power plant, which has 4 × 300 MW single-shaft mixed-flow reversible pump turbines, is designed to have an installed capacity of 1200 MW.
In this paper, a comparative analysis was performed on two energy storage solutions: small-scale underground pumped hydro storage (PHS) and high-temperature thermal energy storage (HTTES).

However, the construction of pumped storage power stations (PSPS) is limited by topography, land availability [8] and high capital costs [9] and has negative impacts on the surrounding landscape, environment, and nearby residents [10]. Therefore, before the construction of PSPS, the location issue is of utmost concern.
