Further, in this embodiment, the preset score of each index is obtained by specifically sorting the score of each index of each key technology, that is, combining the judgment criteria and the objective actual situation of each index to obtain the index score Q of the current situation of the regional construction Ai (i ═ 1,2,3, … x); each technical guidance index score Q corresponding to each key technology selected by region Bi (j) (i ═ 1,2,3, … y) (j ═ 1,2,3, … n); each development strategy index score Q corresponding to each key technology selected by region Ci (j)(i＝1,2,3,…z)(j＝1,2,3,…n)。

In this step, the current building status indicator is weighted to score S 1 Weighted score S with technical guide index and development strategy index of each key technology KB 、S KC Adding to obtain weighted total score G of each key technology K (K ═ 1,2,3, … n). The formula is as follows:
G K ＝S 1 +S KB +S KC ；
in the formula, G K Representing a weighted total score of a certain key technology; s 1 The weighted score of the current building status index of the region is expressed; s KB A technical guide index weighting score representing a certain key technology of the region; s KC And expressing the weighted score of the key technical development strategy index of the region.

It should be noted that, after the weighted sum of each target technology in this step is matched with the pyramid model evaluation criteria of each target technology, a technical route of each project standard technology suitable for the area can be obtained, and a technical route determined by each target technology is synthesized to make a technical route of the area modernized power grid.
According to the power grid technical route differential formulation method, through the multiple evaluation indexes and the weight ratio, power grid technical routes can be formulated in a differential mode according to different development degrees, policies of different regions and different development targets, the formulated routes can be matched with the construction requirements of a modern power grid, more reasonable scientific guidance is provided for formulation of the modern power grid technical routes, and the modern power grid is promoted to be scientifically and orderly constructed.
To help understanding, an embodiment of the present application takes a modernized grid of a district as an example, and a scheme of the present application is described:
(1) determining the technical scheme of the power grid in the area A:
the planning application technology for combing the power supply, the power grid, the load and the energy storage of the power grid in the area A is shown in the following table:
table 2A regional power grid technical scheme
(2) Key technology pyramid model:
(2.1) carrying out hierarchical processing on each key technology selected in the step (1):
the hierarchical carding is carried out according to different technical routes of each technology, and the technical route of the technology is divided into 4 layers by taking an intelligent power distribution network as an example, as shown in fig. 2. The remaining techniques may be layered similarly.
(2.2) making a judgment standard of a corresponding level of each technical route:

TABLE 4 typical cut points for index scores
The indexes include qualitative indexes and quantitative indexes. Because the quantitative indexes have the problem of non-uniform dimension, which leads to the unavailability of the evaluation result, the quantitative indexes are normalized, so that the processed evaluation indexes have no dimension, and the value range is in a reasonable interval.
