Therefore, the effective utilization of run-of-river hydropower for the absorption of PV energy serves as the motivation for this study. To achieve complementary absorption of run-of-river hydropower and photovoltaic (PV) energy, reliable predictions of PV resources within the watershed are essential.
The complementary operation of cascade hydropower and PV generation can be achieved by flexibly adjusting the output of hydropower generator units to reduce curtailment of solar power, whereby the output of the hydropower units is flexibly adjusted based on the situation of PV generation to match its output (Ma et al., 2019).
(2) Under the premise of considering ecological flow, measures are taken to reduce the impact of PV power generation uncertainty by introducing pump stations in hydropower stations, and the introduction of pump stations increases the absorption capacity of PV power generation.
Complementation with hydropower is an important solution to solve the problems of grid connection and consumption of photovoltaic generation. Considering the randomicity of photovoltaic output and runoff, hydropower station with good regulation capability is often used as a complementary power source of photovoltaic generation.
Although introducing different pumping stations can enhance the utilization rate of PV power generation, a 3 MW pumping station is enough based on comprehensive considerations of economic, technical, and environmental factors. FIGURE 7. The PV power generation utilization rate of pump stations with different capacities.
(2) This study proposes the introduction of pump stations in hydropower plants to enhance the synergistic effects between hydropower and PV generation, thereby increasing the consumption capacity of PV generation and meeting the ecological flow requirements of hydropower plants.
