In order to further explain the accuracy and feasibility of the invention, a construction project of a certain place in northwest of China is taken as an example for analysis, the project comprises a combined system formed by a wind power station with installed capacity of 150MW, a photovoltaic power station with 50MW and a pumped storage power station with 40MW for simulation research, the load is reduced in equal proportion according to a daily load curve of the place, the scheduling cycle is one day, and the time is divided into 24 time intervals. The detailed parameters of the typical daily wind speed and the light radiation data are shown in table 1. Table 2 shows the reservoir capacity and load data on the underground pumped storage power station
TABLE 1
TABLE 2
The data in tables 1 and 2 are input into the home machine simulation software to obtain the output power of the combination of wind, light, pumped storage, wind-light complementation and wind-light pumped storage, and the power combination obtained from the home machine simulation software is compared with the load to obtain the graphs in fig. 3, 4 and 5. As can be seen from fig. 3, the wind turbine set generates electricity all day long in one day, the output force at noon is minimum, and the output power fluctuation is large; the photovoltaic array only generates electricity at 19:40 pm at 6:30 pm, the output is the largest at noon, and the output power fluctuation is small; the two have larger complementary characteristics in time distribution. As can be seen from fig. 4, the peak-to-valley difference of the wind-solar complementary output is smaller than the peak-to-valley difference of the wind-solar independent output and the light-solar independent output, but the fluctuation of the complementary output is still very large, which causes a large impact to the grid during grid connection; in addition, the wind-solar complementary output curve cannot track the load curve, and the load requirement cannot be met in many time periods. When the wind-solar complementary output is large, the pumped storage power station works in a pumped state to store energy, and if the residual output exists, the combined system transmits power to the power grid. When the wind and light output is small, the pumped storage power station works in a water discharge state to generate power, and if the requirement cannot be met, the power grid transmits power to the combined system. As can be seen from fig. 5, the output fluctuation of the wind, light and pumped storage combined system is small, the impact on the power grid caused by the wind and light grid connection is reduced, the output curve trend of the combined system is basically consistent with the load curve trend, and the load curve tracking effect is ideal.
