Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are intended for purposes of illustration and explanation only and are not intended to limit the present disclosure.
In the prior art, traditional wind resource assessment is mainly proposed from the perspective of wind energy overall reserve and available conditions, but the commercial development of offshore wind power is not only related to the characteristics of wind conditions, but also closely related to other natural and economic factors. Reanalysis data are basically adopted in the traditional wind resource evaluation process, verification of actually measured data is lacked, and the uncertainty of offshore wind resource evaluation is increased; and when the offshore wind resources are evaluated by comprehensively considering multiple factors, the problems of overlapping and omission exist, and the distribution condition of the offshore wind resources cannot be comprehensively and accurately described. In the method, parameter information of the wind power plant to be evaluated from different angles is obtained, the reanalysis data can be used, the actually measured data is added, importance weights of different parameters are determined according to an analytic hierarchy process, an evaluation scheme of resources such as offshore resources can be established from multiple angles, the importance of offshore wind resource evaluation can be improved, and important reference is further made for site selection of the offshore wind power plant.
The embodiment of the disclosure provides a comprehensive evaluation method for offshore wind resources, and fig. 1 is a flowchart illustrating the comprehensive evaluation method for offshore wind resources according to an embodiment of the disclosure. As shown in fig. 1, the method comprises the steps of:
and step S11, determining comprehensive evaluation parameters of offshore wind resources according to wind resource time data measured by a anemometer tower in any wind power plant within a preset time period.
The wind resource time data specifically includes that a wind tower in the wind farm is continuously monitored within a period of time, for example, within one year, so as to obtain the wind speed within the period of time and the wind direction corresponding to the wind speed. And the wind resource time data is used for calculating the comprehensive evaluation parameters of the offshore wind resources.
It should be noted that, when importance evaluation is performed on the offshore wind resources of a plurality of wind farms, the wind farms to be evaluated may be listed as wind farms to be evaluated, and the following steps are performed for all the wind farms to be evaluated.
Further, the offshore wind resource comprehensive evaluation parameters comprise wind energy resource index parameters, stability index parameters and atmosphere and environment index parameters;
wherein the wind energy resource indicator parameter comprises at least one of wind power density, effective wind speed incidence, and abundance level incidence; the stability index parameter comprises at least one of a coefficient of variation and a dominant wind direction frequency; the atmospheric and environmental index parameters comprise at least one of offshore distance, water depth and atmospheric stability.
And step S12, eliminating dimension influence of the offshore wind resource comprehensive evaluation parameters.
Specifically, since a plurality of evaluation parameter indexes are involved in the comprehensive evaluation of the offshore wind energy resource, and dimensions and attributes of the parameter indexes are different from each other, and direct comparison is difficult to perform, all indexes are normalized before the comprehensive analysis and evaluation so as to eliminate the influence of the dimensions. Wherein, the dimension is composed of two parts: the number and the unit of the evaluation parameter indexes are different from one another, and the evaluation methods and the evaluation degrees are different from one another due to the difference in the size and the unit of the physical quantity, and the evaluation tendency of each evaluation parameter index on the evaluation target is also different.
In the step, the influence of dimension can be eliminated by normalizing the used indexes by adopting a range method; and negative evaluation parameter indexes which describe the evaluation target in a negative way exist in the offshore wind resource comprehensive evaluation parameters, so that the negative indexes are subjected to positive processing while normalization is performed, so that the evaluation trends of all the evaluation parameter indexes on the evaluation target tend to be the same, namely, the evaluation indexes all show positive evaluation trends, and the execution in the following steps is facilitated.
Further, whether the offshore wind resource comprehensive evaluation parameter is described as a forward indicator is judged based on the correlation between the numerical value of the wind energy resource index parameter and the offshore wind resource.
When judging whether the offshore wind resource comprehensive evaluation parameter is described as a forward index, judging whether the index value of the offshore wind resource comprehensive evaluation parameter meets the requirement that the evaluation of the evaluation target is better when the index value is larger.
After judgment, the wind power density, the effective wind speed occurrence rate, the abundance level occurrence rate and the dominant wind direction frequency can be judged to be forward indexes; the variation coefficient, the offshore distance and the water depth are negative indexes; atmospheric stability does not participate in trend evaluation as it is generally characterized by a dimensionless value of the moniobushf length.
Further, when the offshore wind resource comprehensive evaluation parameter is described as a forward direction index, the wind energy resource index parameter is normalized by adopting the following formula:
when the offshore wind resource comprehensive evaluation parameter is described as a non-positive index, namely a negative index, the wind energy resource index parameter is normalized by adopting the following formula:
wherein x isijIs an initial value, yijIs a value after normalization, and m are both positive integers.
In this step, after normalization processing, the output target values are all within the [0,1] interval, and negative indicators are subjected to positive processing, so that the evaluation trends are consistent.
Step S13, acquiring the preferred evaluation scheme score of the wind power plant based on the normalization value of the offshore wind resource comprehensive evaluation parameter and the preset weight corresponding to the offshore wind resource comprehensive evaluation parameter; wherein the preset weight is used for representing the relative importance degree of each parameter between the corresponding standards of the parameter.
Further, the method for calculating the preset weight comprises the following steps:
firstly, an AHP hierarchical analysis model is established, wherein the AHP hierarchical analysis model comprises a target layer, a criterion layer and a scheme layer.
And then, inputting the wind energy resource index parameters, the stability index parameters and the atmospheric and environmental index parameters into a criterion layer in the AHP hierarchical analysis model, wherein the target layer is an optimal evaluation scheme.
The analytic hierarchy process includes decomposing the decision problem into different hierarchical structures based on the total target, sub targets in different layers, evaluation criteria and specific alternative schemes, solving the characteristic vector of judging matrix to obtain the priority weight of each element in each layer to one element in the upper layer, and combining the final weights of the alternative schemes to the total target in recursion mode with the sum of weights to obtain the optimal scheme.
It should be noted that, constructing a hierarchical structure model is a target that needs to be decided in the embodiments of the present disclosure, and the index that affects the decision and the object that is decided are divided into a target layer, a criterion layer, and a decision layer according to the relationship between them. The target layer is the purpose of decision making, the criterion layer is the influencing factor of decision making, and the decision making layer is the decision making result which can be selected. In the embodiment of the invention, a hierarchical structure model shown in FIG. 2 can be constructed according to the wind energy resource index parameter, the stability index parameter and the atmospheric and environmental index parameters.
And constructing an 8-order judgment matrix according to the comprehensive evaluation parameters of the offshore wind resources, and calculating preset weights of all parameters representing the evaluation of the offshore wind resources in the judgment matrix.
In this step, the judgment matrix represents a comparison of the relative importance of all the evaluation parameter indexes of the current layer with respect to one of the evaluation parameter indexes of the previous layer. In practical application, the pair-wise comparison factors are 8 at most, namely, each layer does not exceed 8 influence factors. The element a of the decision matrix in the embodiment of the present invention is given using the 1-9 scale of Santy. In specific implementation, a 1-9 scaling method is adopted, and a lower table judgment scale table is constructed according to each evaluation parameter index contained in the hierarchical structure model.
TABLE 1 judgment Scale Table
The corresponding judgment matrix is:
the relative importance of each evaluation parameter index is scored by constructing a judgment matrix according to an expert scoring method by means of knowledge storage of experts in the field and relevant experience of the experts in the subject to obtain a judgment scale table, and a corresponding 8-order judgment matrix is determined according to the judgment scale table.
After the 8-order judgment matrix is constructed, consistency check is carried out on the judgment matrix, and in the embodiment of the invention, more reasonable CR is selected as an index for measuring the consistency of the judgment matrix. When CR is less than 0.1, the judgment matrix is considered to have satisfactory consistency, otherwise, the judgment matrix must be judged again until the consistency meeting the conditions is achieved. If the value of CR is less than 0.1, the next step can be performed by a consistency check. If the consistency can not be checked, the judgment matrix needs to be adjusted again, and whether the importance degree of the two-two comparison of some indexes is not in accordance with the objective reality or the strength of the two-two comparison is not good. And when the judgment matrix does not pass the consistency check, the judgment matrix is unqualified to be constructed, and the judgment matrix needs to be reconstructed.
And the consistency ratio CR value of the final matrix is 0.078 and less than 0.1, which indicates that the matrix meets the consistency test, and the calculated weight has consistency. It should be noted that the evaluation parameter indexes used for evaluating the importance of the offshore wind resource integration in the embodiment of the present invention may include, but are not limited to, a wind energy resource index parameter, a stability index parameter, and an atmosphere and environment index parameter, when an evaluation parameter index having more influence appears, the determination matrix needs to be reconstructed, and in specific implementation, the evaluation parameter index and the evaluation parameter index weight may be flexibly adjusted according to the situation so as to adapt to the continuous change of the offshore wind farm. In the embodiments of the present invention, the above-described index is used as an example for explanation.
Finally, obtaining a weight distribution table of each parameter of the offshore wind resource comprehensive evaluation, wherein the weight distribution table is shown as the following table:
TABLE 2
Further, based on the preset weight, giving a preferred evaluation scheme weight coefficient of each parameter in the offshore wind resource comprehensive evaluation parameters respectively.
After the weights with consistency are obtained through calculation, the weights are given to the optimal evaluation scheme weight coefficients corresponding to the parameters respectively.
And then multiplying the weight coefficient of the preferred evaluation scheme of each parameter by the corresponding normalized value of the comprehensive evaluation parameter of the offshore wind resources, and adding to obtain the score of the preferred evaluation scheme of the wind power plant. And carrying out the same operation steps on the wind power plants to be evaluated participating in the evaluation to obtain the optimal evaluation scheme scores of all the wind power plants to be evaluated.
And S14, sequencing the scores of the preferred evaluation schemes of the wind power plants in a descending order, and determining the best evaluation result of the wind power plants.
Specifically, after the scores of the optimal evaluation schemes of all the wind power plants to be evaluated are obtained, the wind power plants to be evaluated are sorted in the order from big to small, the importance of the wind power plants to be evaluated is sorted, and then the optimal wind power plants or the site selection of the optimal wind power plants can be determined according to the sorting result.
