FIG. 1 is a flow chart of a water-wind-solar complementary operation method according to an embodiment of the invention, as shown in FIG. 1, the flow comprises the following steps:

step S101, a first output dataset of a hydropower station is obtained.

The first output data set may include an initial hydropower critical output, a wind-solar output, and a first hydropower output of the hydropower station within each preset time period within a preset time range. In this embodiment, the preset time range is one month, and each preset time period is each day in one month.

The total hydropower requirement is to ensure that no waste wind and waste light are generated, and the step hydropower output which needs to be reduced when the total output of the hydropower and the wind exceeds the period of the channel, namely the lower limit of the output which can be reduced by hydropower.

The total hydropower can be adjusted to be smaller values of the channel surplus output space and the step hydropower surplus output space, namely the upper output limit of the hydropower which can be increased.

Step S102, based on the initial hydropower critical output and wind-light output, complementary adjustment is carried out on the water-light of the hydropower station in each preset time period, and a second output data set of the hydropower station is obtained.

When the total hydropower is adjustable and larger than the total hydropower requirement, the water light superposition output exceeds the channel and the discarded part of the photovoltaic output can be completely consumed by changing the hydropower output. At the moment, the photovoltaic can be completely absorbed through daily complementary adjustment, and the absorption rate of the photovoltaic reaches 100%.

When the total hydropower is smaller than the total hydropower requirement, a part of the original photovoltaic output to be discarded can be eliminated by adjusting the hydropower output process, but a part of the ultra-channel photovoltaic output still needs to be discarded, at the moment, the photovoltaic output cannot be completely eliminated by the complementary adjustment in the day, the photovoltaic consumption rate in the day is less than 100%, and the water-light complementation in the month needs to be continued.

Specifically, a target water volume of a reservoir connected to the hydropower station may be calculated from a target hydropower output of the hydropower station.

And step S105, determining a water-wind-solar complementary operation result of the hydropower station based on the target hydropower output and the target water quantity.

Further, after the step S2031, step S203 further includes:

and S2034, comparing the first hydropower output with the initial hydropower critical output to obtain a second comparison result when the first output is larger than the second output.

Specifically, when the first output is larger than the second output, namely the total hydropower requirement is larger than the total hydropower adjustability, the raw water electric output (first hydropower output) on the same day is continuously compared with the initial hydropower critical output on the same day.

And step S2035, determining the target water electric power according to the second comparison result.
