Abstract

The invention discloses a market partition method and device based on node electricity prices. The method includes: S1, obtaining electricity price data in a preset period in a target area to generate a data set; S2, obtaining a cluster center matrix and a random matrix, and performing random The matrix is ​​initialized and normalized to generate a membership matrix, and the number of iterations is set to 1; S3, judge whether the current number of iterations is less than the preset threshold, if not, S5, update the clustering center matrix, according to the updated clustering The center matrix and the data set update the membership matrix, execute S4; S4, judge whether the updated membership matrix meets the convergence condition, if not, add 1 to the number of iterations, execute S3, and S5 if it is satisfied; S5, output the updated clustering center matrix and the updated membership matrix, each node is classified according to the updated membership matrix, and the target area is partitioned to generate a partition result. This method can reasonably partition multiple regions.

Description

technical field [0001] The invention relates to the technical field of electric power market, in particular to a method and device for market partitioning based on node electricity price. Background technique [0002] At present, the power spot market in most provinces in China is still in the development stage of formulating construction plans or trial operation. Among them, Guangdong, as one of the first batch of pilot power spot markets, released the first power spot market transaction rules on August 30, 2018 . Guangdong has made it clear in the settlement rules that the power generation side settlement price is the node power price of the physical node where the unit is located, and the user side is settled using the unified settlement point power price settlement; The arithmetic mean of the 15-minute node electricity price. Among them, the user-side unified settlement point electricity price is defined as the weighted average price of each node in the whole market du...
