Abstract

The invention discloses a market partitioning method and device based on nodal electricity price. The method includes the following steps: S1, acquiring electricity price data of a target area in a preset period to generate a data set; S2, acquiring a clustering center matrix and a random matrix, initializing and normalizing the random matrix to generate a membership matrix, and setting the numberof iterations to 1; S3, judging whether the current number of iterations is less than a preset threshold, executing S5 if the current number of iterations is not less than the preset threshold, and if the current number of iterations is less than the preset threshold, updating the clustering center matrix, updating the membership matrix according to the updated clustering center matrix and the data set, and executing S4; S4, judging whether the updated membership matrix meets the convergence condition, adding 1 to the number of iterations and executing S3 if the updated membership matrix doesnot meet the convergence condition, and executing S5 if the updated membership matrix meets the convergence condition; and S5, outputting the updated clustering center matrix and the updated membership matrix, classifying each node according to the updated membership matrix, and partitioning the target area to generate a partitioning result. The method can be used to reasonably partition multipleareas.

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 trading 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 during...
