Power system operation evaluation method and system under source network load storage multi-element collaborative interaction

Abstract

The invention discloses a power system operation evaluation method and system under source-network-load-storage multi-element collaborative interaction, and the system comprises a data import module, a three-level index evaluation module, a first-level index evaluation module and a result display module, the data import module is used for inputting power spot market operation original data and scores, and carrying out the primary processing of the data; the third-level index evaluation module is used for calculating subjective weight vectors of various indexes by adopting an analytic hierarchy process based on the preliminarily processed data, calculating objective weight vectors of the various indexes by adopting an entropy evaluation method, and optimizing and solving in a weight interval obtained by the subjective weight vectors and the objective weight vectors by taking level difference maximization as a target to obtain final index weights; the first-level index evaluation module endows the data with a weight value in the previous module based on the preliminarily processed data and adds up products to obtain an evaluation result of each first-level index; and the result display module displays evaluation results of the third-level indexes and the first-level indexes. According to the method, the operation of the electric power spot market is specifically and comprehensively evaluated, an evaluation system is established through the steps of index normalization processing, index weighting and index synthesis, and factors such as the structure, supply and demand, economical efficiency, adequacy, reliability, power generation structure and pollutant emission during the operation of the current electric power spot market are fully investigated.

Description

technical field [0001] The present invention relates to a technology in the field of power grid intelligent control, in particular to a power system operation evaluation method and system under multiple collaborative interactions of source, network, load and storage. Background technique [0002] The defects and insufficiencies of the existing power system evaluation indicators are: the index construction is messy and the level is not clear enough; the main body of the system considered is mainly concentrated on the power generation side, and the impact of the collaborative interaction of source, network, load and storage is not taken into account in the index evaluation. Based on the principles of scientificity, practicability, and comprehensiveness, the present invention constructs a three-level index evaluation system adapted to the power system, starting from the perspectives of source, network, load, and storage, and considering the influence of source, network, load, an...
