Embodiment

[0032] Such as figure 1 As shown, the evaluation method for the spatial collaborative development of distribution network grids based on the source-grid-load interaction includes the following steps:

[0033] S1: Construction of dynamic index system: respectively construct the power grid input index system, power grid output benefit index system and regional characteristic index system;

[0034] At this stage, it is necessary to construct the project input and output dynamic index system and the external characteristic classification index system respectively.

[0035] In the engineering dimension, mainly based on the substation's own capital investment, combined with technical, social, economic, political and other output benefits, a comprehensive evaluation system for input-output three-layer penetration key indicators is constructed. The indicator system can be dynamic according to different project types and purposes. Adjust the content of the indicator system.

Abstract

The invention discloses a power distribution network grid space collaborative development evaluation method based on source-network-load interaction. The method comprises the following steps: S1, a dynamic index system is constructed; S101, a power grid input index system and a power grid output benefit index system obtain project side evaluation, wherein the project side evaluation comprises project side input and output data superposition; S102, a regional feature index system, a project side input-output data and an external feature data form regional side evaluation, and a regional side evaluation is subjected to regional feature classification to obtain a regional feature classification index system; S2, engineering and regional input-output comprehensive evaluation is performed: an engineering input-output comprehensive evaluation result and a regional feature classification evaluation result are obtained; and S3, deep evaluation of typical cases is performed: engineering dimension microscopic evaluation and regional dimension macroscopic evaluation are performed. The method is used for evaluating whether the power grid can meet the requirements of regional economic development or not, power grid planning is integrated into regional development planning, accurate investment of the power grid is implemented, and the method is of great significance to social economic development.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a distribution network grid space collaborative development evaluation method based on source-grid-load interaction. Background technique [0002] With the development of smart grids, the development and utilization of renewable energy, and the advancement of power market reforms, tremendous changes have taken place in power production, transmission, trading, and use. Among them, the collaborative interaction of "source-network-load" is a The operating mode that can realize the maximum utilization of energy resources. "Source-network-load" interaction refers to various interaction forms among power supply, load and grid through source-source complementarity, source-network coordination, network-load interaction and source-load interaction to achieve a more economical, efficient and safe power increase. The target of system power dynamic balance capability. [0003] As a hub...
