Problems solved by technology

A large number of distributed power grids will have a huge impact on the planning and operation of the distribution network. The existing grid planning of the distribution network only considers the one-way flow of the power flow, and lacks the analysis method for the distributed power access. and technical means, resulting in distribution network grid planning can no longer meet the needs of the new generation of energy development

Abstract

The invention discloses an active gridding planning method based on distributed power supply access. The method comprises the following steps: S1, analyzing current situations of economy, a power supply and a power grid in a planning area; S2, performing gridding division on the planning area, and determining a power supply type planning target in each grid; S3, predicting power demand and distributed power supply in each power supply grid in the long-range years, and analyzing the influence of distributed power supply access on load prediction; S4, determining power distribution network gridding planning schemes under various situations according to the power demand and the distributed power supply prediction result; S5, analyzing the current situation of the absorption capability of thepower grid distributed power supply, and formulating a transition grid scheme; and S6, analyzing the investment and construction effects of the active gridding plan. Through resource assessment, consumption analysis and targets and transition grid formulation of distributed power supply, orderly construction of the power distribution network is guaranteed. Full access and full consumption of the distributed power supply are achieved, and coordinated development of new energy and power grids is promoted.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an active grid planning method based on distributed power access. Background technique [0002] With the increasing human demand for energy and the depletion of traditional petrochemical energy, the development of new energy has been vigorously developed. In recent years, distributed power grid-connected projects represented by distributed photovoltaics have experienced rapid growth. A large number of distributed power grids will have a huge impact on the planning and operation of the distribution network. The existing grid planning of the distribution network only considers the one-way flow of the power flow, and lacks the analysis method for the distributed power access. And technical means, resulting in distribution network grid planning can no longer meet the needs of the new generation of energy development. Contents of the invention [0003] The purpose of the presen...
