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.
What is a cascade hydropower station?In particular, the cascade hydropower stations situated within grid dispatch area are ideal for this role. When connected to the power grid together with wind and photovoltaic power, they form a cascade hydro-wind-photovoltaic complementary generation system (CHWPCGS) .
What is a cascade hydropower and photovoltaic complementary joint generation system?Fig. 1. Cascade hydropower and photovoltaic complementary joint generation system operation mode. As illustrated in Figure 1, the cascaded water-light complementary system consists of a runoff hydropower station, a photovoltaic power station, and a delivery system.
Can cascade hydropower promote complementary power generation systems?The cascade hydropower enables to maintain the stability of hybrid power plant and therefore can be perceived a promising way of promoting complementary power generation systems . The utilization of complementary energy sources raises a challenge on how to coordinate their operation to maintain reliable power injection into the power grid.
How does Cascade hydropower work?Since the cascade hydropower in this example primarily relies on the runoff type power station, it lacks annual adjustment and water storage capabilities, com-monly referred to as “relying on the weather for power generation ”, meaning that electricity production is directly proportional to the available water supply.
