Abstract

The invention relates to a VaR-considering electric power large user flexible load evaluation method and system. The method comprises the steps of collecting five-dimensional historical data of electric power large user flexible load participating in system peak regulation scheduling; grouping the electric power large user data by taking users as units; using Monte Carlo simulation to separately simulate the data of each dimension; separately establishing a frequency distribution map for each dimension data; determining a confidence level of the data of each dimension; determining quantiles ofthe data of each dimension, and querying parameter values corresponding to the quantiles of the data of each dimension in the frequency distribution diagram, wherein the parameter value is the VaR evaluation index under the confidence level corresponding to each dimension. According to the method, corresponding risk value evaluation indexes can be given according to different risk bearing capacities of the power grid, clear, comprehensive and accurate guidance suggestions are given to flexible load scheduling of large power consumers, and the stability and economical operation of the power grid are improved.

Description

technical field [0001] The invention belongs to the technical field of flexible load evaluation of large electric power users, and in particular relates to a flexible load evaluation method and system of large electric power users considering VaR. Background technique [0002] The continuous growth of power peaks has made the power sector continue to increase power generation to cope with the high demand for electricity in society. At the same time, with the emphasis on environmental protection and the promotion of distributed clean energy, the power system is gradually connected to a large number of distributed energy. . The intermittent operation of a large number of generating units used for peak regulation will bring higher costs to power operation and greatly reduce the economics of power grid operation. At the same time, although distributed energy has the characteristics of cleanness, its volatility and randomness have brought great challenges to the reliable operati...
