Abstract

The embodiment of the invention discloses an evaluation method and an evaluation device for evaluating the investment benefit of a power distribution network. The method comprises the following stepsof establishing a power distribution network investment benefit overall evaluation index system, and deriving a monomer evaluation index system according to the overall evaluation index system; according to the data of each monomer evaluation index in each power distribution network monomer item in a target area, determining the score of the power distribution network monomer item; according to the data of an overall evaluation index in the target area, determining the score of each overall evaluation index; and ranking all power distribution network monomer items according to the scores of all power distribution network monomer items. According to the invention, the method and the device are designed for the insufficient fund condition during the construction of the power distribution network. According to the score of each overall evaluation index, the score of each power distribution network monomer item or the ranking result of power distribution network monomer items in the targetarea, an optimal combination of power distribution network monomer items is determined. Therefore, the monomer item construction of the power distribution network is further optimized on the basis ofthe time sequence. The contradiction between the power development demand and the limited investment fund can be relieved, and the utility maximization of investment benefits is realized.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and device for evaluating investment benefits of distribution networks. Background technique [0002] In recent years, the scale of the power grid has continued to expand, and the cost of power grid construction, operation, and maintenance has risen rapidly. The investment of power companies is facing tremendous pressure, and higher requirements have been put forward for the investment efficiency and benefits of the distribution network. How to avoid low-efficiency and ineffective investment, scientifically arrange investment projects, rationally grasp investment timing, pay attention to input-output benefits, effectively prevent and avoid operating risks, and steadily improve the economic benefits of power grids have become problems that electric power companies need to study and solve in depth. [0003] At present, domestic and foreign distribution network investme...
