Embodiment 1
[0065] This embodiment is a coordinated and optimized embodiment involving small hydroelectric generators, wind power generation, and photovoltaic power generation. figure 1 In order to use the method of embodiment 1 to coordinate and optimize the grid structure; the small hydroelectric generator group is connected to the first input end of the 10-35kV substation, the wind farm is connected to the second input end of the 10-35kV substation, and the photovoltaic power station is connected to the 10-35kV substation. The third input terminal of a 35kV substation, the energy storage device is connected to the fourth input terminal of a 10-35kV substation, and the 10-35kV substation is connected to an external power grid through a transformer; figure 2 The flow chart for the coordination and optimization of grids containing small hydroelectric power plants and other renewable energy sources includes the following steps:
[0066] S1. Obtain the total net load value P of all small hydro...
Embodiment 2
[0083] Repeat Example 1 with the same steps described above, the difference is that the optimization target is the maximum total power generation of the small hydroelectric generator group, and the objective function is
Embodiment 3
[0085] Repeat Example 1 with the same steps as described, the difference is that the optimization goal is the minimum amount of discarded water of the small hydropower plant group, and the objective function is Among them, | represents the assumption. △V i (t) represents the amount of water discarded during the period t of the i-th small hydropower station.
