Problems solved by technology
[0003] At present, distribution network planning cannot grasp the overall situation of regional diversified loads, and lacks mature methods and tools for evaluating the distribution network to accommodate diversified loads, resulting in disordered and disordered access to diversified loads, which has an impact on the safe and stable operation of the power grid
At the same time, there is a lack of diversified load rationality evaluation methods, and it is difficult to track and feedback its application

Embodiment Construction
[0066] The present invention will be described in detail below with reference to the examples.
[0067] A diversified load diversification capability assessment method provided by the present invention includes the following steps:
[0068] 1) Get basic data such as the model, model parameters and operation data of the regional grid to be connected to the diversified load, and the diversified load initial access scheme is prepared;
[0069] 2) According to the diversified load of the diversified load, the access position and access scale of the diversified load, and the regional grid to which the access diversified load is partially divided according to the access scale of the diversified load, wherein The access size of the diversified load includes parameters such as access capacity and access voltage level;
[0070] 3) Establish a rational evaluation index system based on the change of the regional grid operating state before and after the multi-load access, and determine the w...

The invention relates to a method and system for assessing the diversified load accommodation capacity of a distribution network, comprising the following steps: 1) Obtaining the basic data of the regional power grid, and formulating an initial access plan for diversified loads; 2) Layering and analyzing the regional power grid 3) Establish a rationality evaluation index system to evaluate the rationality of the hierarchical sub-component grid; 4) Based on the division results of the hierarchical sub-components of the regional power grid, build a calculation model to obtain the operating data of the regional power grid, and based on the reasonable 5) Determine whether the current diversified load access scheme is the maximum consumption capacity scheme, if so, stop the calculation, otherwise pass The maximum capacity of the regional power grid to accommodate diversified loads is obtained through cyclic iterations. The invention can be widely used in the evaluation and optimization work of the multi-load grid connection scheme of the distribution network.
Description
Technical field [0001] The present invention relates to the technical field of distribution network diversified load planning, and more particularly to a distribution grid diversified load diversification capability assessment method and system based on a hierarchical component element. Background technique [0002] In recent years, with the continuous development of the social economy, the load in the distribution network is increasingly exhibiting diversity and complexity, and different types of loads are different from the reliability of power systems and the quality of power supply. Multi-volume load such as electric vehicles, energy storage systems, microfrigence systems, reflects greater value in energy conservation and emission reduction, load management, renewable resource utilization, power quality improvement, system reliability improvement, etc., make up for the shortcomings of traditional distribution networks . However, due to the large-scale multi-load access networ...
