The purpose of building a pumped storage power station
The purpose of building a pumped storage power station includes:Energy Storage: They act like a giant water battery, storing excess energy when demand is low and releasing it when demand is high, thus providing a flexible and reliable energy management solution1.Renewable Energy Integration: Pumped storage power plants allow for the storage of clean energy produced from renewable sources, making them ideal for power grids reliant on renewable energy2.Balancing Supply and Demand: They help balance energy demand and supply, ensuring a stable energy supply during peak demand periods3.Operational Efficiency: The configuration of two water reservoirs at different elevations allows for efficient energy generation and storage4.These factors contribute to the overall effectiveness and reliability of energy systems. Pumped storage hydropower acts like a giant water battery, storing excess energy when demand is low and releasing it when demand is high, offering a flexible and reliable solution for energy management. Pumped storage power plants (PSPP) allow you to store clean energy that is produced from renewable energy sources (RES). Therefore, it is an ideal solution for power grids dependent on energy generated by photovoltaic and wind farms. Building a pumped storage power station presents numerous advantages and challenges that deserve careful consideration. 1. Energy storage capability is a key benefit, allowing for the balance between energy demand and supply. 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).
Mapping the potential for pumped storage using existing
Currently, most pumped storage stations have discharge durations between 6 and 24 h (Fig. 2 b) [26]. However, in the future, more and more PHS plants might be built to store variable energy at the weekly, monthly, seasonal and pluri-annual scale.
