Embodiment 1
[0043] The i-th provincial electric energy alternative planning model in the lower model can be described as:
[0044]
[0045] s.t.L ij ≤y ij ≤ U ij ,1≤j≤m
[0046]
[0047]
[0048]
[0049] is the alternative power index issued by the headquarters for the i-th province according to the plan, and the unit is 100 million kWh; x i is the headquarters decision variable; y i is the amount of electric energy substitution planned by the i-th province; m is the number of industries participating in electric energy substitution;
[0050] the y ij Plan the electric energy substitution amount of the jth field for the i province;
[0051] k ij The cost coefficient that needs to be paid to replace 10,000 kWh of electricity in the jth field for i province;
[0052] L ij and U ij are the lower limit and upper limit of the electric energy replacement quantity in the jth field of the i province, respectively.
[0053] The objective function of each province is to hop...
Embodiment 2
[0058] The above model can be described as:
[0059]
[0060]
[0061] Among them, n represents the number of participation in provincial electric energy alternative planning; x=[x 1 ,x 2 ,...,x n ] represents the electric energy to be planned to replace the electric quantity vector, x i is the decision variable of the headquarters, that is, according to the planning decision y of province i i Feedback the alternative electric quantity index adjusted to province i, y=[y 1 ,y 2 ,...,y n ] represents the provincial electric energy substitution planning vector, y i It is set by the i-th provinces through the optimization of the lower model, In order for the headquarters to issue an alternative power index to province i according to the plan, the unit is 100 million kWh; in order to complete the planned index of the headquarters, the adjusted planned total amount must be greater than the initial planned total amount of the headquarters, so the constraint must be sati...
Embodiment 3
[0066] refer to figure 1 , the present invention also discloses the algorithm framework of the above-mentioned planning method based on the two-layer electric energy substitution planning model, as follows:
[0067] (1) Set initial parameters and order
[0068] (2) For the i-th province, optimize and solve the lower model to get y i ,
[0069] (3) put y i Feedback to the upper model, optimize and solve the upper model, and get x i ,
[0070] (4) Calculate F(x), if the absolute value of the difference from the previous round of F(x) is less than the preset positive threshold ξ, the algorithm ends; otherwise, set x i Feedback the lower layer model from step (2) for loop iterations until the end of the algorithm.
