Abstract

The invention discloses a user division method used for accurate load shedding. The method comprises the steps of obtaining power consumption load information of load shedding users; constructing a three-dimensional feature vector space of the load shedding user according to the load capacity, the peak duration time and the high load duration time; selecting a user to divide a clustering center according to a convex polygon perimeter maximum criterion; calculating the membership distance between each load shedding user and each division clustering center, and dividing the load shedding users by taking the minimum membership distance as a criterion. The load shedding users can be divided scientifically and reasonably, so that the resource utilization rate and the system response efficiency of the load shedding system can be effectively improved.

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...
