Embodiment Construction

[0064] In order to clearly illustrate the technical solution provided by the present invention, the load curve period division method provided by the present invention will be specifically described below in conjunction with the design flow chart in the accompanying drawings.

[0065] Aiming at the problems that most of the current inventions only use the clustering method to classify the load curves and extract the typical daily load curves, but cannot divide the load curves into time periods, the present invention aims to overcome the deficiencies of the prior art, and adopts fuzzy clustering and model The identification method divides the load curve into periods, completes the equivalent processing of complex power grid load data, effectively compresses the amount of load data, and reasonably determines the switching action time of the dynamic reconstruction of the distribution network, which can improve the operating efficiency of the distribution system. economy and reliab...

Abstract

The invention provides a method for dividing load curve periods suitable for distribution network reconfiguration. The method includes load standardization; dividing load curve periods; calculating equivalent loads of load curve periods; calculating mode closeness; determining the load curve Equivalent way. The technical solution provided by the invention adopts the method of fuzzy clustering and pattern recognition to divide the load curve into time periods, completes the equivalent processing of complex power grid load data, effectively compresses the amount of load data, and reasonably determines the dynamic reconstruction of the distribution network The switching action time can improve the economy and reliability of power distribution system operation.

Description

technical field [0001] The invention relates to a load characteristic analysis method, in particular to a load curve period division method suitable for distribution network reconfiguration. Background technique [0002] During the operation of the distribution network, the load is always changing with time. Due to the randomness of the load change, it is impossible to have two identical operating states during the operation of the distribution network. If each operating state is analyzed separately, The amount of calculation is very large; on the other hand, because people's work and rest patterns and electricity consumption habits are relatively stable, the load changes in the distribution network are regular, with certain correlation and reproducibility, so according to the load in the distribution network According to the characteristics of the curve, the moments with large load fluctuations in a period of time (1d) are divided into different time periods, and the moment...
