Construction status of pumped storage power station in madagascar

Can pumped storage power stations be built among Cascade reservoirs?

The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation.

Why do we need pumped storage power stations?

Hence, construction of pumped storage power stations can effectively improve the flexibility of the clean energy base and support the depth of new energy consumption .

Can pumped storage power stations reduce peaking pressure?

Considering the change of the intra-day load demand can reduce the peaking pressure of the power receiving end. More research on the economics of the pumped storage power station can be carried out when the relevant mechanisms of China's new power market are further improved.

Can pumped storage power stations support a high-quality power supply?

Hence, to support the high-quality power supply, this research explores the complementary characteristics of the clean energy base building different types of pumped storage power stations, and recognizes the efficient operation intervals of the giant cascade reservoir.

Why are hydropower and pump stations used as flexible resources?

Among them, hydropower and pump stations are used as flexible resources. Facing the uncertainty of the power output of WPP, the hydropower station needs to determine its power generation process according to the output process of WPP, and the pump station needs to consume excess electricity when the power output of WPP is larger.

What is the efficiency coefficient of pumped storage pump stations?

The efficiency coefficient of PPSPS ranges from 65% to 87% (80% in this research) . 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.
