Suofengying Power Station Power Generation Time

Is the Daily generation scheduling of Wujiang Cascade hydropower plants valid?

Taking the daily generation scheduling of Wujiang cascade hydropower plants in southwest China as an example, the validity of the model was verified. The conclusions can be drawn as below.

How many MW of wind & PV power plants are installed in Wujiang?

According to the Planning on the Integration of Renewable Energy in the Wujiang River Basin, the planned installed capacities of wind and PV power plants integrated into the three cascade hydropower stations are 929 MW and 1950 MW respectively.

How many MW is a pumping station in the Wujiang River?

A pumping station constructed between H1 and H2 reservoirs is assumed to have an installed capacity of 300 MW. The above hydropower stations, pumping station, wind power and PV power stations are integrated through the hydraulic and electric connections to form an HPSH-wind-PV system. Fig. 3. The geographic location of the Wujiang River.

Do different water delay formulations affect the power output process?

This indicates that the different water delay formulations directly affect the discharge distribution process between the cascade hydropower plants, which in turn leads to the deviation of the power output process. The power output process of each hydropower plant in model 2 and model 3 remains basically the same.

Which Xianfeng PV plant is a representative PV plant?

In this study, the Xianfeng PV plant which has been put into operation near the hydropower stations is chosen as the representative PV plant, and the planned PV plants are assumed to have the same meteorological conditions as the Xianfeng PV plant.

Can optimum scheduling of Cascade hydropower plants maximize daily generation profit?

Generally, acceptable calculation time can be attained with satisfactory results [ 33 ]. Given the problems mentioned above, this study focuses on the optimum scheduling of the cascade hydropower plants participating in the contract and spot markets to maximize the daily generation profit of hydropower enterprises.
