Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a flowchart of an implementation of a method for establishing a power grid business optimization model according to an embodiment of the present invention, which is described in detail below:
Coupling refers to the phenomenon that two or more systems or motion modes are influenced by each other through various interactions so as to be combined, and is a dynamic association relationship of interdependence, mutual coordination and mutual promotion under benign interaction among all subsystems. There are also multiple links and multiple coupling actions between different power grid services. Based on the above, the embodiment of the invention provides a power grid service coupling index for quantitatively evaluating the coupling effect between different power grid services.
Referring to fig. 2, the coupling effect between the grid services is mainly embodied in two aspects of a service development process and a service development result. Correspondingly, the power grid business coupling indexes are mainly divided into two types of process coupling and result coupling. In the process of service development, various invoked resources are divided, so that the coupling effect of various services can be decoupled from different types of resource angles, and the coupling degree between different power grid services can be effectively quantized. Based on the above, in the process of service development, a production resource coupling degree index, a technical resource coupling degree index, a marketing resource coupling degree index and a management resource coupling degree index are constructed, and four power grid service coupling indexes are totally constructed.
After the service is developed, the influence of the development effect of one service on the other service needs to be quantified. The influence here mainly includes three kinds of acceptances, complementarity and substitution. The service receiving is the inheritance and supplement of the original service in the scope and the field, such as the receiving of the power data value-added service and the traditional data acquisition service; the complementation between the services means that the two services complement each other and cooperatively develop in the service field and the content, and the effect of 1+1>2 is realized through the mutual coupling action between the services; the replacement between services means that contradiction and competition relation exists between services, and one service is gradually replaced by another service gradually along with the continuous development of society. Based on the above, after the service development is completed, a service acceptance index, a service complementation index and a service substitution index are constructed, and three power grid service coupling indexes are totally constructed.
When the grid business coupling indexes are weighted, a hierarchical analysis method (AnalyticHierarchyProcess, AHP) can be adopted. Referring specifically to fig. 3, an analytic hierarchy model is constructed for each grid business coupling index. When the chromatographic analysis model is constructed, the service coupling degree can be used as a decision target layer, the process coupling and the result coupling are respectively used as decision criterion layers, and the production resource coupling degree index, the technical resource coupling degree index, the marketing resource coupling degree index, the management resource coupling degree index, the service acceptance degree index, the service complementation degree index and the service substitution degree index are used as evaluation index layers.
And judging indexes of each layer in the chromatographic analysis model by using a 1-9 ratio scale method, so as to determine a judgment matrix corresponding to the chromatographic analysis model. Referring to fig. 4 and 5, when indices of each layer in a chromatographic analysis model are evaluated using a 1-9 ratio scale, each index is quantized according to the evaluation criteria shown in fig. 4 and 5 according to the importance level thereof, thereby obtaining a judgment matrix. And judging that the feature vector corresponding to the maximum feature value of the matrix is a weight vector, normalizing the weight vector to obtain the weight of each layer of index, calculating the final weight of the index of the layer according to the weight of the index of the previous layer, and finally obtaining the final weight of each power grid service coupling index in the evaluation index layer.
In order to avoid the paradoxical evaluation result of the judgment matrix, consistency test is required. The consistency test can be performed according toTo verify consistency.
Wherein CR represents random consistency ratio, RI represents average random consistency index, and the value of RI is only equal to the judgment momentThe order of the array is related, and can be obtained by looking up a table, wherein CI represents a consistency index, andwherein lambda is max Represents the maximum feature root of the judgment matrix, and A represents the order of the judgment matrix.
In general, the smaller CR, the better the judgment matrix consistency. When CR is less than the first preset value, it is indicated that the judgment matrix has acceptable satisfactory consistency, otherwise, adjustment and correction should be performed on the judgment matrix. The first preset value here may be, for example, 0.1.
Referring to table 1, the correspondence between the numerical value size of RI and the order a of the judgment matrix only is shown in table 1.
TABLE 1
A | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
RI | 0 | 0 | 0.58 | 0.90 | 1.12 | 1.24 | 1.32 | 1.41 | 1.45 | 1.49 | 1.51 |
According to the table 1 and the order of the judgment matrix, the RI value can be determined, and then consistency test is carried out. And finally obtaining the weight of each power grid service coupling index.
Alternatively, referring to fig. 6, step 102 may include:
optionally, step 201 may include:
wherein lambda is 1 Represents a first measure of ambiguity, g (I u ) Representing the u-th power grid business coupling index I u N represents the number of grid service coupling indicators.
The AHP method belongs to a subjective weighting method, and the weight of each power grid service coupling index obtained based on the AHP method has subjectivity and may have deviation. Therefore, the embodiment of the invention is used for correcting the weight of each power grid service coupling index by calculating the first fuzzy measure, so that the accuracy of a single evaluation value of the subsequent calculated service coupling degree is improved.
Service coupling exists between every two grid services. Thus, the service coupling degree between every two grid services needs to be calculated in turn. That is, there is a degree of service coupling between every two grid services.
When calculating the service coupling degree, for a group of services (including two power grid services), a preset evaluation value of each power grid service coupling index in the group of services needs to be acquired first. It can be appreciated that, to improve the evaluation accuracy, each grid service coupling index corresponds to at least one preset evaluation value. According to a preset evaluation value and the first fuzzy measure, a single evaluation value of the service coupling degree of the group of services can be correspondingly calculated.
Optionally, according to the preset evaluation value and the first fuzzy measure, calculating a single evaluation value of the service coupling degree between two power grid services respectively, including:

According to the above formula, it can be understood that the number of the single evaluation values of the service coupling degree is equal to the number of the preset evaluation values corresponding to each grid service coupling index.
And 203, calculating the comprehensive evaluation value of the service coupling degree between the two power grid services according to all the calculated single evaluation values.
Optionally, before step 203, the method further includes:
and 204, acquiring the weight of the preset evaluation value, and calculating a second fuzzy measure according to the weight of the preset evaluation value.
wherein lambda is 2 Represents a second measure of ambiguity, g (q k ) Represents the kth preset evaluation value q k M represents the number of preset evaluation values.
Accordingly, step 203 may include:
and calculating the comprehensive evaluation value of the service coupling degree between the two power grid services according to all the single evaluation values and the second fuzzy measure.

By setting a plurality of preset evaluation values for each power grid service coupling index and setting weights for each preset evaluation value, the accuracy of the comprehensive evaluation value of the service coupling degree can be effectively improved. Correspondingly, the embodiment of the invention is used for correcting the weight of each preset evaluation value by calculating the second fuzzy measure so as to improve the accuracy of the comprehensive evaluation value of the service coupling degree.

Optionally, the combination weighting of each service contribution index can be obtained by carrying out combination weighting on each service contribution index through an AHP-entropy weighting method.
The AHP-entropy weight method is a method for combining subjective weight determined by the AHP method with objective weight determined by the entropy weight method to obtain subjective and objective integrated combination weight. And the key degree of each service contribution index is judged more comprehensively through the combination weight. Specifically, referring to fig. 8, subjective weighting is performed on each service contribution index by constructing an analytic hierarchy process and a judgment matrix by using an AHP method on one hand, and objective weighting is performed on each service contribution index by using an entropy weighting method on the other hand.
