Site selection method for power distribution network switching station in planning area

Abstract

The invention relates to a site selection method for a power distribution network switching station in a planning area, and belongs to the technical field of power system distribution network planning. The method comprises the following steps: establishing a site selection mathematical model of the switching station, establishing association between the site selection mathematical model of the switching station and a particle swarm algorithm, predicting a power load in a planning area and obtaining a long-term mature load value of the planning area, initializing parameters of the particle swarm algorithm, and determining a power supply range of the switching station. And calculating the total cost of the switching station of each address combination, respectively updating the speed and position vectors of particles according to a particle swarm algorithm, and finally outputting and verifying a result. According to the method, a switching station site selection mathematical model is originally provided, the switching station site selection mathematical model is associated with a particle swarm algorithm, and continuous adjustment and continuous optimization are carried out in the particle swarm algorithm iterative calculation optimization process until a switching station position address meeting the minimum total cost is finally found out.

Description

technical field [0001] The invention relates to a site selection method for a distribution network opening and closing station in a planned area, and belongs to the technical field of power system distribution network planning. Background technique [0002] The switching station is an important part of the urban distribution network. The selection of its location is an important link in the planning of the urban distribution network, which is related to whether the power supply at the load point is reliable and whether the structure of the distribution network is reasonable. For a planning area, how to accurately and quickly determine the opening and closing of the area on the basis of comprehensively considering the principles of opening and closing, various influencing factors affecting the construction of the opening and closing, and accurately analyzing the characteristics of the location of the opening and closing The optimal solution of the switchgear, that is, the num...

AI Technical Summary

Problems solved by technology

[0003] At present, in the planning and design of the distribution network, the location of the opening and closing mainly depends on the experience of the designer, and the manual layout is carried out on the CAD control detailed drawing provided by the urban planning department, which is time-consuming and laborious, and the accuracy is not high, and the final result is difficult to guarantee. is the optimal solution

At present, there are no literature reports on the use of computers to select the location of the switching station and the power supply range.
