Embodiment

[0041] A method for extracting a power consumption pattern, comprising the following steps:

[0042] Step 1. Establish the target data set: establish the enterprise electricity consumption sequence rec according to the electricity consumption data corresponding to the electricity consumption enterprises in the target industry in a specific year and month, rec={1 ,power 1 >,2 ,power 2>,...

[0043] n ,power n >},1≤n≤12, month n Represents the nth month, power n Represents the power of the nth month;

[0044] The original data set S is as follows, where each […] represents the twelve-month data of an enterprise, and each (…,…) represents the electricity consumption of an enterprise in a certain month:

[0045] First enterprise:

[0046] [(1,4153),(2,2954),(3,527),(4,2603),(5,4419),(6,1113),(7,3264),(8,3220),(9, 4941),(10,4779),(11,462),(12,3959)];

[0047] Second business:

[0048] [(1,2134),(2,1918),(3,700),(4,69),(5,3120),(6,1061),(7,417),(8,2070),(9,1669) ,(10,1014)...

Abstract

The invention discloses a power consumption mode extraction method and system. The method comprises the following steps: establishing a characteristic tuple sequence of a power utilization enterprise,and calculating a distance between two characteristic tuples based on a maximum common subsequence of the characteristic tuple sequence; And performing distance-based clustering on the enterprise power consumption sequence to obtain a power consumption mode of the target industry. The design thought of the maximum common subsequence is adopted, so that the method is more suitable for the situation that the power consumption of enterprises in the same industry is similar, more correct input is provided for extraction of the power consumption mode of a user, and a foundation is laid for constructing a more effective mode extraction model.

Description

technical field [0001] The invention relates to a method for extracting a power consumption pattern, in particular to a method for extracting a power consumption pattern in the electric power industry. Background technique [0002] In the power industry, changes in the electricity consumption patterns of enterprises often reflect changes in the operating conditions of enterprises. Enterprises with better operating conditions show a steady increase in their electricity consumption patterns; enterprises with poorer operating conditions often experience sudden drops in electricity consumption, or even repeated fluctuations. In addition, affected by factors such as national laws and regulations, the changes in electricity consumption of enterprises in an industry often have some common trends. [0003] Therefore, the evolution of the industry's electricity consumption pattern reflects the operating conditions within the industry. However, the traditional manual analysis method...
