Power grid development dynamic comprehensive evaluation method based on Bayesian network

Abstract

The invention discloses a power grid development dynamic comprehensive evaluation method based on a Bayesian network. At present, the evaluation method for power grid development still needs further study. The power grid development dynamic comprehensive evaluation method comprises the steps of: selecting a power grid development evaluation index, and constructing a power grid development level evaluation index system; preprocessing collected index historical data, and carrying out index normalization processing and index dimensionless processing separately; constructing a Bayesian power grid evaluation network model; calculating sample data comprehensive evaluation scores by adopting an electric power dynamic comprehensive evaluation method based on motivation or punishment to obtain a power grid comprehensive evaluation value, and regarding the power grid comprehensive evaluation value as a training sample of the Bayesian power grid evaluation network model; training the constructed Bayesian power grid evaluation network model to obtain a trained Bayesian power grid evaluation network model; and inputting a test sample for testing. The power grid development dynamic comprehensive evaluation method can calculate to obtain an objective and precise power grid development evaluation result, and can make a reasonable evaluation of the power grid development.

Description

technical field [0001] The invention belongs to the field of power grid evaluation, in particular to a dynamic comprehensive evaluation method for power grid development based on a Bayesian network. Background technique [0002] Electricity is the lifeblood of national economic and social development. At present, the construction and development of my country's power system is still facing enormous pressure. Power grid development assessment can effectively understand the current status of power grid development, measure the power supply capacity, power supply reliability, economy, etc. of the power grid, and can provide theoretical support and decision-making basis for the future development of the power grid, thereby ensuring the scientific and rational development of the power grid. It can be seen that the power grid development evaluation has important and far-reaching significance. [0003] In my country, many scholars have carried out research on the evaluation of po...
