Abstract

The invention discloses a power transmission system planning method and device considering wind and light correlation and a storage medium. The method comprises the steps of obtaining a historical data set of power system parameters and random variables; performing scene division on the historical data set according to a Mini Batch K-Means clustering method; respectively determining parameters and types of Copula functions according to the scene data, and judging optimal rattan structures in the scenes by adopting AD distance; establishing a mixed vine Copula model according to the optimal vine structure in each scene, and generating a wind-light load sample set; and inputting the wind-light load sample set and the power system parameters into the power transmission system planning model, and outputting a power grid planning result. According to the method, the Mini Batch K-Means algorithm is used for scene division, so that the operation time is shortened; the AD distance is used as a rattan structure judgment criterion, the modeling precision of the mixed rattan Copula is improved, and the credibility of the power transmission system extension planning method is further improved.

Description

technical field [0001] The present application relates to the technical field of power transmission systems, and in particular to a power transmission system planning method, device, equipment and storage medium considering the correlation between wind and wind. Background technique [0002] In recent years, with the increasing energy demand and increasingly severe environmental problems, the installed capacity of renewable energy has increased year by year. As we all know, wind power and photovoltaic output are highly random and intermittent, and these characteristics will bring severe challenges to the expansion planning of the power system. At the same time, the widespread loads in the power system are affected by the differences and irregularities in the behavior of power users, and there are also strong uncertainties. On the other hand, the randomness between wind power, photovoltaic output and load is not completely independent, but there is a complex correlation betw...
