Problems solved by technology

[0004] The traditional distribution network planning system investment mainly considers the initial investment capital of the power grid project, ignoring many follow-up links such as operation, maintenance, renovation and scrapping after the project is implemented, and lacks the social cost in the whole life cycle of the planning scheme (such as power outage loss cost, environmental protection cost) overall consideration

Embodiment Construction

[0058] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0059] On the premise of satisfying the safe and stable operation of the power grid, the calculation model of the whole life cycle cost of the distribution network planning scheme is given, and the minimum life cycle cost is taken as the objective function, and the distribution network path planning is optimized by using the cluster exclusion niche genetic algorithm , through the comparison and analysis of the life cycle costs of different switch arrangements, the power distribution planning scheme with the smallest life cycle is obtained. Finally, the feasibility and effectiveness of the method are proved by an example. The goal of loss reduction is achieved by reconfiguring the distribution network.

Abstract

The invention discloses a method for planning a distribution network based on full life cycle cost management. The method comprises the process that a calculation model for the full life cycle cost of a distribution network planning scheme is provided under the premise of meeting safe and stable running of a power grid, distribution network path planning is optimized by using a clustering crowding niche genetic algorithm by taking the minimum full life cycle cost as an objective function, a distribution planning scheme with the minimum full life cycle is acquired through performing comparative analysis on the full life cycle cost of different switch arrangement patterns, and finally the feasibility and effectiveness of the method are proven through calculating examples. The method provides a new analysis method and an assistant decision-making theory basis for distribution network planning, running and transformation and operation benefits of electric power companies, power grid formulation technologies are optimized, and a planning scheme with the optimal economical efficiency is acquired.

Description

technical field [0001] The invention relates to the field of distribution networks, in particular to a distribution network planning method based on full life cycle cost management. Background technique [0002] Distribution network planning refers to seeking a set of optimal decision variables (substation location and capacity, feeder path and size, etc.) The sum of damage and reliability loss costs is the smallest, so that the planning scheme can meet the operation requirements and be economical at the same time. [0003] The traditional distribution network planning meets the predetermined reliability of a certain load level with the least system investment. The distribution network planning of the whole life cycle cost comprehensively considers the cost of each stage of the power grid construction project, and coordinates the reliability and economy of the power grid. . [0004] The traditional distribution network planning system investment mainly considers the initia...
