Research And Application Of Distribution Network Loss Reduction Planning Economic Evaluation System

Power network loss reduction planning work has been carried out gradually, but theloss reduction planning is still not perfect. The following issues need to be resolved:whether the power network loss reduction planning program is optimized and economic;whether it meets the project investment criteria; how to quantify the implementation effectof power grid loss reduction planning.Firstly, the feasibility study’s effect, style, content and steps of distribution networkloss reduction planning program are clarified. The construction principle and screeningprinciple of the evaluation indicators are established. At the same time, a number ofpretreatment of indicators is made. Empowerment of the indicators and evaluation methodis chosen. The assessment process and economic evaluation index system applicable to thedistribution network loss reduction planning characteristics are given. FuzzyComprehensive Evaluation Method is used to quantify the advantages and disadvantagesof various programs as well as indicators. By contrast between the two planning programwith the status quo power network of the example can find the problems of the status quopower network and implementation results of the power network planning, andsuggestions for improvement in planning and transformation are given. The evaluationsystem is not only suitable for single program assessment, but also suitable formulti-program evaluation. This is to provide help for practical engineering programdecision-making and distribution network loss reduction planning.Secondly, the basis information of power techno-economic analysis and evaluationwill inevitably have a deviation due to various objective and subjective reasons. Thebreak-even analysis is selected as a measure of the uncertainty analysis. Sensitive factorsthat affect the final decision-making program are carried out a detailed computationalanalysis.Finally, combined with the technical and economic characteristics of power networkloss reduction planning programs, the main function of the power network evaluationsystem and its implementation is analyzed and described in detail; the software algorithm is given too. This system can not only make an evaluation on planning program, but alsomake an evaluation on technical operation, applies equally to the evaluation oftransmission and distribution network. The flexibility of power network evaluation isgreatly improved, meeting the actual needs of the project.
