Embodiment Construction

[0023] Such as figure 1 Shown, a kind of network planning method based on comprehensive evaluation of the present invention, comprises the following steps:

[0024] S1 analyzes the status quo of the power system, predicts the load demand of the power grid, and performs power supply planning.

[0025] S2 proposes multiple preliminary power grid planning schemes according to the analysis, prediction and planning results of step A.

[0026] S3 conducts electrical calculations for multiple preliminary grid planning schemes.

[0027] S4 According to the results of electrical calculations, calculate the loss cost of each preliminary grid planning scheme, and judge whether the preliminary grid planning scheme meets the grid security index requirements, and eliminate the preliminary grid planning schemes that do not meet the grid security indicators among multiple preliminary grid planning schemes scheme, the preliminary grid planning scheme that meets the grid security index is inc...

Abstract

The invention discloses a power grid planning method based on comprehensive assessment. On the basis of quantitative analysis of a power supply reliability index, a power comprehensive cost index and the power grid safety index, the method comprises the steps: building a power grid planning mathematic model based on comprehensive assessment; carrying out the quantitative calculation of a power grid planning design from three aspects: power supply reliability, economical performances and safety, thereby achieving the more objective comparison, selection and optimization of the power grid planning design scheme, preventing the subjective factors of a decision maker from causing adverse effects on the power grid planning, enabling the power grid planning to balance the power supply reliability and the economical performance more reasonably on the basis of guaranteeing the safety, and improving the economic benefits and social benefits of power grid investment.

Description

technical field [0001] The invention relates to the technical field of power grid construction, in particular to a comprehensive evaluation-based power grid planning method. Background technique [0002] Traditional power grid planning methods lack quantitative analysis of power supply reliability indicators and economic indicators, so the selection of grid planning schemes is subjective, and it is impossible to provide objective judgments on whether the grid planning and construction are scientific and economically reasonable. The basis will cause the power grid planning scheme to fail to meet the needs of social development and users. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical purpose of the present invention is to provide a comprehensive evaluation-based power grid planning method to improve the traditional power grid planning method that cannot perform quantitative analysis on power supply reliability indic...
