Power generation facility output characteristic evaluation method and system based on space-time distribution map

Abstract

The application relates to the technical field of distributed power generation, and provides a power generation equipment output characteristic evaluation method and system based on a space-time distribution diagram. The method comprises the following steps: obtaining historical dynamic data and static spatial data of distributed power generation equipment interactively; after time sequence alignment of the dynamic data, multi-granularity data segmentation is performed to obtain subdivided-granularity dynamic time data of a plurality of power generation equipments; one-dimensional quantification of the dynamic time data is performed to output subdivided-granularity quantification values; a device distribution diagram layer is constructed based on the static spatial data, the subdivided-granularity quantification values are time sequence correlated to the layer, and a time sequence multi-granularity output characteristic layer is obtained; two-dimensional rule mining is performed based on the layer to obtain time dynamic rules and spatial distribution rules; and space-time weighted rules are output to obtain the space-time output characteristics of the distributed equipment, so that the technical problem of one-sided and lagging output characteristic evaluation is solved, and the technical effect of improving the comprehensiveness and timeliness of output characteristic quantification evaluation is achieved.
