Power grid planning quality-efficiency multi-period evaluation method based on Lagrange function

Abstract

The invention provides a power grid planning quality-effect multi-period evaluation method based on a Lagrange function, and the method comprises the following steps: carrying out whole process division and time period decomposition of power distribution network planning based on the previous experience and planning requirements, and providing support for the integrated management of the power distribution network planning; S2, on the basis of the whole-process time periods, constructing quality-effect indexes of power distribution network planning work in each time period, and effectively controlling the quality and efficiency in the power distribution network planning process; and S3, converting different dimensions of each index in the step 2 based on a Lagrange function, and constructing a power grid planning quality-effect comprehensive quantitative evaluation model to provide a means for quality-effect management of the whole power distribution network planning process. The whole power distribution network planning process can be evaluated, so that the quality and efficiency of power distribution network planning are improved, and a basis is provided for a power distribution network planning investment strategy.

Description

technical field [0001] The invention relates to the field of distribution network planning engineering technology and management in the electric power industry, aiming at evaluating and analyzing the multi-period quality and benefit in the specific power grid planning process in the distribution network planning management review work. Background technique [0002] The planning and development of distribution network is not only the optimization, improvement and application of distribution network planning technology, but also the effective docking with a series of needs of economic and social development at the macro level. "Effective" is the criterion for judging the development of distribution network planning. It is not only the "self-feeling" of power grid enterprises, but also the feelings of all aspects of society about the effectiveness of distribution network reform and development. At the mesoscopic level, the planning and development of distribution network needs ...

AI Technical Summary

Problems solved by technology

[0003] At present, the evaluation of distribution network planning is carried out from the overall technical quality, and does not involve the quality and efficiency index evaluation of each stage in the evaluation planning process at different time periods, and the evaluation of each index is only a simple weighting and evaluation method. And there is a lack of connection with the economy, and there is a certain one-sidedness in the investment decision-making of the distribution network
