Abstract

The invention discloses an optimization selection method for to-be-constructed projects of a power distribution network. The method comprises: analyzing a current situation index and a target index of the power distribution network in a region where the to-be-constructed projects are; grading the indexes; performing quantitative calculation on the indexes and calculating a weight of each index; calculating a final score of each to-be-constructed project; and calculating an optimization selection result of the to-be-constructed projects of the power distribution network according to the final scores as well as fund demands and total available funds of the to-be-constructed projects. According to the method, the current situation index and the target index of the power distribution network in the to-be-constructed project region are considered, an improvement effect on the indexes of the power distribution network is quantified, an objective actual effect is combined with expert experience to form an overall score of each project, and final to-be-constructed project selection is performed according to the total available funds and the project scores; the blindness and randomness of the to-be-constructed project selection process are avoided; and the method is scientific, reasonable and high in operability.

Description

technical field [0001] The invention specifically relates to a method for optimizing and selecting projects to be built in a distribution network. Background technique [0002] With the continuous development of the national economy, people's living standards have been steadily improved and improved, and the power load has continued to grow. The pressure on power grid construction has become increasingly prominent, especially the distribution network. The distribution network directly faces the terminal link of power users, and is an important link to promote the economy and improve people's livelihood. [0003] There are many constraints in the construction and planning of distribution network. At present, the State Grid has clear regulations on the construction goals of the distribution network, and various planning indicators related to the distribution network have been quantified in the form of guidelines and other forms. However, the projects that can be constructed ...
