Can pumped storage systems be integrated into water supply systems?
The management of a pumped storage system integrated into water supply systems is still little explored. The integration of dynamic energy pricing with PAT operation represents an opportunity for water utilities to reduce their costs. The computational model developed using optimization algorithms allows for efficient operation of PAT in WSSs.
What is a pumped storage facility?
Pumped storage facilities are built to push water from a lower reservoir uphill to an elevated reservoir during times of surplus electricity. In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation, which is why it is sometimes called a “water battery”.
How pumped storage works?
In water scarce areas, pumped storage schemes are used as an alternative to conventional hydroelectric power stations to provide the power needed during peak periods. Instead of the water being discharged, it is retained in the system and re-used.
How does the Drakensberg pumped storage scheme work?
The Drakensberg Pumped Storage Scheme generates electricity during peak periods in its role as a power station, but also functions as a pump station in the Tugela-Vaal Water Transfer Scheme. Water is pumped from the Thukela River, over the Drakensberg escarpment into the Wilge River, a tributary of the Vaal.
How pumped storage pump stations affect the water balance relationship?
The construction of pumped storage pump stations among cascade reservoirs will change the traditional water transfer relationship between UR and LR, thus affecting the water balance relationship. In the HWPPHS, the water balance of UR and LR are expressed by (32) and (33) respectively:
How does a pumped storage hydropower plant work?
Image from IKM 3D. Pumped storage hydropower facilities rely on two reservoirs at different elevations to store and generate energy. When other power plants generate more electricity than the grid needs, a PSH plant can use that power to pump water into the upper reservoir.
