[0046] This invention provides a comprehensive evaluation method for the development scheme of compressed air energy storage projects, including:

[0047] Obtain the values ​​of N indicators from K compressed air energy storage project development plans to be evaluated;

[0048] The N indicators are divided into positive indicators or negative indicators, and each indicator is made to be in the same direction, resulting in N in the same direction indicators; wherein, the N indicators include M positive indicators and NM negative indicators.

[0049] Based on the N homogenization indices, the TOPSIS method is used to construct the positive and negative ideal vectors of the comprehensive optimization index for each compressed air energy storage project development scheme, thereby obtaining the comprehensive optimization positive ideal vector.

[0050] Calculate the difference between each of the K compressed air energy storage project development schemes and the comprehensive optimal positive ideal vector, and determine the compressed air energy storage project development scheme with the largest difference as the comprehensive optimal development scheme;

[0051] Collect information on actual project development plans and evaluate the improvement indicators of the actual project development plans and the comprehensive optimized development plan.

[0052] The technical solution and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] like Figure 1 As shown, the embodiments of the present invention include the following steps:

[0054] Step 1: Evaluate the given compressed air energy storage project development plan using five indicators: engineering cost, energy conversion efficiency, carbon emissions, site selection limitations, and discharge duration.

[0055] Step 2: Use the TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution, or the distance method between superior and inferior solutions) to evaluate the development schemes of the compressed air energy storage project and select the comprehensive and optimal development scheme;

[0056] Step 3: Collect information on actual development project plans and evaluate the improvement indicators of actual development plans and the comprehensive optimized development plan.

[0057] In step 1, the given compressed air energy storage project development plan is evaluated using five indicators: engineering cost, energy conversion efficiency, carbon emissions, site selection limitations, and discharge duration.

[0058] 1) Five indicators were used to evaluate the development plans of K compressed air energy storage projects: engineering cost, energy conversion efficiency, carbon emissions, site selection restrictions, and discharge duration.

[0059] 2) Determine whether each indicator is a positive or negative indicator. If a higher value is better, it is considered a positive indicator: for example, energy conversion efficiency and discharge duration are considered positive indicators. If a lower value is better, it is considered a negative indicator: for example, project cost is considered a negative indicator.

[0060] 3) Since carbon emissions and site selection constraints are qualitative indicators, this embodiment assigns values ​​of 0 or 1 directly to the carbon emissions and site selection constraints indicators for different schemes according to positive indicator logic: the carbon emissions indicator for schemes with carbon emissions is assigned a value of 0, and the carbon emissions indicator for schemes without carbon emissions is assigned a value of 1. The site selection constraint for schemes with site selection constraints is assigned a value of 0, and the site selection constraint for schemes without site selection constraints is assigned a value of 1.

[0061] 4) For the development scheme of the i-th compressed air energy storage project, the m-th index which belongs to the positive index in the scheme is calculated according to formula (1) to obtain the homogenization index x. im :

[0062]

[0063] Among them, X im Let maxX be the value of the m-th indicator in the development plan of the i-th compressed air energy storage project. m Let X be the maximum value of the m-th indicator in the development scheme of K compressed air energy storage projects. m Let m be the minimum value of the m-th indicator in the development scheme of K compressed air energy storage projects; m = 1, 2, ..., M.

[0064] 5) For the development scheme of the i-th compressed air energy storage project, the n-th index, which belongs to the reverse index in the scheme, is calculated according to formula (2) to obtain the same index y. in :

[0065]

[0066] Among them, Y in Let maxY be the value of the nth indicator in the development plan of the i-th compressed air energy storage project. nLet Y be the maximum value of the nth indicator in the development schemes of K compressed air energy storage projects. n Let n be the minimum value of the nth indicator in the development scheme of K compressed air energy storage projects; n = M+1, ..., N.

[0067] According to the embodiments of the present invention, in step 1, there are four compressed air energy storage project development schemes to be evaluated: Case 1, Case 2, Case 3, and Case 4, i.e., K=4. Based on the development scheme information, evaluation indicators such as project cost, energy conversion efficiency, carbon emissions, site selection limitations, and discharge duration are assigned values: Case 1: Project cost 5500 yuan / MW, energy conversion efficiency 55%, carbon emissions assigned 0, site selection limitations assigned 1, discharge duration 5 hours; Case 2: Project cost 7000 yuan / MW, energy conversion efficiency 65%, carbon emissions assigned 1, site selection limitations assigned 0, discharge duration 4 hours; Case 3: Project cost 9000 yuan / MW, energy conversion efficiency 70%, carbon emissions assigned 1, site selection limitations assigned 1, discharge duration 8 hours; Case 4: Project cost 6000 yuan / MW, energy conversion efficiency 60%, carbon emissions assigned 1, site selection limitations assigned 0, discharge duration 6 hours.

[0068] In this embodiment, each compressed air energy storage project development scheme has N indicators. After determining whether an indicator is a positive or negative indicator, energy conversion efficiency and discharge duration are identified as positive indicators, and carbon emission and site selection constraints are constructed as positive indicators. Therefore, M = 4 in this embodiment. Equation (1) is used to obtain the values ​​of the energy conversion efficiency, discharge duration, carbon emission, and site selection constraints of the four compressed air energy storage project development schemes after aligning them. Engineering cost is identified as a negative indicator, and Equation (2) is used to obtain the values ​​of the engineering cost indicator of the four compressed air energy storage project development schemes after aligning them. The values ​​of the evaluation indicators for engineering cost, energy conversion efficiency, carbon emissions, site selection restrictions, and discharge duration in each case are as follows after being aligned: In Case 1, the values ​​of the above-order indicators are {1, 0, 0, 1, 0.25}; in Case 2, the values ​​are {0.57, 0.67, 1, 1, 0}; in Case 3, the values ​​are {0, 1, 1, 0, 1}; and in Case 4, the values ​​are {0.86, 0.33, 1, 1, 0.5}.

[0069] In step 2, the TOPSIS method is used to evaluate the development scheme of the compressed air energy storage project and select the comprehensive and optimal development scheme:

[0070] 1) Normalize the homogenization index according to equation (3) to obtain the j-th evaluation index z of the i-th compressed air energy storage project development scheme. ij :

[0071]

[0072] 2) The positive and negative ideal vectors of the comprehensive optimization index for each compressed air energy storage project development scheme are calculated and constructed by adopting the TOPSIS method, wherein the positive ideal vector z of the comprehensive optimization index is calculated and constructed according to equation (4). + Calculate and construct the negative ideal vector z of the comprehensive optimization index according to formula (5). - :

[0073]

[0074] 3) By adopting the Delphi method and consulting experts, a weight vector Λ=[λ1 λ2 λ3 λ4 λ5] was assigned to five indicators: project cost, energy conversion efficiency, carbon emissions, site selection constraints, and discharge duration.

[0075] 4) Calculate the positive ideal vector z of the development scheme and comprehensive optimization index of the i-th compressed air energy storage project according to Equation (6) and Equation (7) respectively. + Comprehensive optimization index negative ideal vector z - The gap d i + d i - :

[0076]

[0077] 5) Calculate the difference between the development scheme of the i-th compressed air energy storage project and the comprehensive optimal positive ideal vector according to formula (8):

[0078]

[0079] Where 0≤D i ≤1, D i The larger the value, the better the overall development plan.

[0080] From the embodiments of the present invention, after normalizing the indicators according to formula (3) in step 2, the normalized values ​​of the engineering cost, energy conversion efficiency, carbon emissions, site selection restrictions, and discharge duration evaluation indicators in each case are as follows: In Case 1, the normalized values ​​of the above-order indicators are {0.697, 0, 0, 0.577, 0.218}; in Case 2, the normalized values ​​of the above-order indicators are {0.398, 0.535, 0.577, 0.577, 0}; in Case 3, the normalized values ​​of the above-order indicators are {0, 0.802, 0.577, 0, 0.873}; and in Case 4, the normalized values ​​of the above-order indicators are {0.597, 0.267, 0.577, 0.577, 0.436}.

[0081] Calculate and construct the positive ideal vector z of the comprehensive optimization index according to formula (4). + Given {0.697, 0.802, 0577, 0.577, 0.873}, calculate and construct the negative ideal vector z of the comprehensive optimization index according to equation (5). - The weighted vector is {0, 0, 0, 0, 0}. Using the Delphi method and consulting experts, a weighted vector of {0.2, 0.2, 0.1, 0.2, 0.3} is assigned to five indicators: engineering cost, energy conversion efficiency, carbon emissions, site selection constraints, and discharge duration. The positive ideal vector z for each case and the comprehensive optimization index is calculated according to equations (6) and (7). + Comprehensive optimization index negative ideal vector z - The difference: d1 in Case 1 + d1 - The values ​​are 0.539 and 0.422 respectively; d2 in Case 2 + d2 - The values ​​are 0.511 and 0.435 respectively; d3 in Case 3 + d3 - The values ​​are 0.405 and 0.625 respectively; d4 in Case 4 + d4 - The values ​​are 0.341 and 0.492, respectively. Finally, according to equation (8), the differences between the four compressed air energy storage project development schemes and the comprehensive optimal positive ideal vector are obtained: Case 1 is 0.439, Case 2 is 0.460, Case 3 is 0.607, and Case 4 is 0.591. Since Case 3 has the largest difference value, Case 3 is the comprehensive optimal development scheme.

[0082] In step 3, information on actual project development plans is collected, and the improvement indicators of the actual project development plans and the comprehensive optimized development plans are evaluated.

[0083] 1) By collecting information on the progress of the actual project development plan, determine whether the actual project development plan is the same as the comprehensive optimal development plan: If the actual project development plan is determined to be the same as the comprehensive optimal development plan based on the project development progress information, then obtain the indicator vector of the actual project development plan. The value of z + The values ​​of the j-th evaluation index are inconsistent with the values ​​of the vector indicators. Then calculate according to formula (9) and the comprehensive optimization index positive ideal vector The difference in values ​​u j :

[0084]

[0085] Take u j The maximum value will be the focus of the next phase of the project plan.

[0086] 2) If the actual project development plan differs from the comprehensive optimal development plan based on the project development progress information, then calculate the index vector of the j-th evaluation index in the actual project development plan according to formula (10). and the index vector of the comprehensive and optimal development scheme The difference in the value d j :

[0087]

[0088] Take d j The maximum value will be the focus of the next phase of the project plan.

[0089] From the embodiments of the present invention, according to step 3, information on the progress of the actual project development plan is collected, and the project development plan that is progressing is identified as Case 3, which is the same as the comprehensive optimal development plan. The index vector {0, 0.802, 0.577, 0, 0.873} of the actual project development plan is obtained according to formula (9), where the values ​​are related to z. + The inconsistencies in the vector {0.697, 0.802, 0.577, 0.577, 0.873} are between the following two indicators: project cost and site selection constraints. Specifically, the project cost indicator has a value of 0, while the corresponding value of the positive ideal vector for the comprehensive optimization indicator is 0.697, resulting in a difference of 0.697. Similarly, the site selection constraint indicator has a value of 0, while the corresponding value of the positive ideal vector for the comprehensive optimization indicator is 0.577, also resulting in a difference of 0.577. Therefore, the maximum value of these two is the project cost, making it the key focus for the next stage of the project development plan.
