Embodiment Construction

[0048] like figure 1 Shown is a schematic flow chart of the method of the present invention: the user division method for precise load shedding provided by the present invention includes the following steps:

[0049] S1. Obtain the power load information of load shedding users; specifically, obtain the total number of load shedding users of the power grid, and the power consumption curve of each load shedding user;

[0050] S2. Construct the three-dimensional feature vector space of load shedding users according to the load, peak duration and high load duration; specifically, the following steps are used to construct the three-dimensional feature vector space of load shedding users:

[0051] A. According to the electricity load information corresponding to each load shedding user of the grid, calculate the average load, peak duration and high load duration corresponding to each load shedding user; the calculation of the average load corresponding to each load shedding user Th...

Abstract

The invention discloses a user division method for precise load shedding, which includes acquiring power load information of load shedding users; constructing a three-dimensional feature vector space of load shedding users according to load amount, peak duration and high load duration; The maximum criterion of the perimeter of the convex polygon is used to select the user division cluster center; the membership distance between each load shedding user and each division cluster center is calculated, and the load shedding user is divided based on the criterion of the minimum membership distance. The invention can divide the load shedding users scientifically and rationally, thereby effectively improving the resource utilization rate and system response efficiency of the load shedding system.

Description

technical field [0001] The present invention specifically relates to a user division method for precise load shedding. Background technique [0002] With the development of economy and technology, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. Therefore, the stable and reliable supply of electric energy has become one of the most important tasks of the power system. [0003] At the same time, with the rapid development of UHV AC and DC power grids, the scale of long-distance cross-regional transmission continues to expand, and the proportion of new energy sources has further increased. Problems such as power overuse of inter-provincial connection lines. The cognitive methods, defense concepts, control technologies and control measures formed on the basis of the traditional AC system have been difficult to adapt to the new requirements of the operation practic...
