Embodiment Construction
[0022] Such as figure 1 As shown, a method for screening urban power grid operation indicators, including steps:
[0023] S100: Obtain original indicators, and group indicators of the same type in the original indicators into a group.
[0024] The original indicator refers to an indicator set used for screening, and the original indicator set includes multiple indicators. Similar indicators are convenient for comparison, and it is easier to select representative KPI indicators from similar indicators. Therefore, in order to reduce the amount of data processing in the subsequent process of screening, firstly, the indicators of the same type in the original indicators are grouped. Specifically, indicators of the same type refer to indicators with the same or similar evaluation objects and content. The specific division method can be based on historical experience data or industry norms. Different groups of indicators can be understood as evaluating different topics (content)....

The invention relates to an urban power grid operation index screening method and system. The method includes the following steps that: indexes of the same type in original indexes are grouped to one group according to index types; core value indexes in the grouped original indexes are selected; factor analysis is performed on the grouped original indexes, and common factors capable of interpreting all the indexes are found out; indexes with largest load are selected from the common factors so as to be adopted as initially selected KPI indexes; and the core value indexes are compared with the initially selected KPI indexes, and a final KPI index set is determined. According to the method, complex calculation processes are not required in a screening process; index screening is carried out based on comprehensive consideration on the core indexes and the KPI indexes which are selected based on the common factors, namely, the index screening is carried out based on comprehensive consideration on the subjective aspect and the objective aspect; and therefore, selected indexes are approved in both of the subjective aspect and the objective aspect, can satisfy the operation and management requirements of an urban power grid and can accurately characterize the operation condition of the urban power grid.
Description
technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for screening urban grid operation indicators. Background technique [0002] The commonly used screening methods for urban power grid operation indicators mainly include: AHP combined with principal component analysis, partial least squares regression, extension theory combined with correlation analysis, gray relational degree method, AHP and Delphi The combination of AHP and interval estimation, the combination of questionnaire survey and cluster analysis, the screening method of forecasting model based on comprehensive validity index and model redundancy check, attribute mathematics and fuzzy comprehensive evaluation method, etc. [0003] Although the above index screening methods can achieve the screening of urban power grid operation indicators to a certain extent, there are still some defects. The main defect is that the subjectivity is too strong, a...
