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 in conjunction with the examples.
[0067] A method for evaluating the diversified load accommodation capacity of a distribution network provided by the present invention includes the following steps:
[0068] 1) Obtain basic data such as the model, model parameters, and operating data of the regional power grid to be connected to diversified loads, and formulate an initial connection plan for diversified loads;
[0069] 2) According to the access position and access scale of the diversified loads in the initial access plan of the diversified loads, and according to the access scale of the diversified loads, the regional power grid to be connected to the diversified loads is divided into layers and components, among which, The access scale of diversified loads includes parameters such as access capacity and access voltage level;
[0070] 3) Establish a rationality evaluation index system according to the changes i...

The invention relates to a method and a system for evaluating the diversified load absorbing capacity of a distribution network, comprising the following steps: 1) acquiring basic data of a regional power network and formulating an initial access scheme of the diversified load; 2) carrying out stratification and component division on that regional power network; 3) establishing a rationality evaluation index system for rationality evaluation of layered and component-based pow grids; 4) building a calculation model to obtain the operation data of the regional power network based on the hierarchical and component division result of the regional power network, and calculating the rationality score value of the regional power network after the diversified load is connected according to the rationality evaluation index system and the operation data of the power network; 5) judging whether that current multi-load access scheme is the maximum absorb capacity scheme, if so, stopping calculation, otherwise obtaining the maximum absorbing capacity of the regional pow network to the multi-load through circulation iteration. The invention can be widely applied to the evaluation and optimization of the multi-load integration scheme of the distribution network.
Description
technical field [0001] The invention relates to the technical field of distribution network diversified load planning, in particular to a method and system for evaluating the diversified load accommodation capacity of distribution network based on layered components. Background technique [0002] In recent years, with the continuous development of social economy, the loads in the distribution network are increasingly characterized by diversity and complexity, and different types of loads have different requirements for power system reliability and power supply quality. Multiple loads such as electric vehicles, energy storage systems, and micro-grid systems have shown greater value in terms of energy saving and emission reduction, load management, renewable resource utilization, power quality improvement, and system reliability improvement, making up for the shortcomings of traditional distribution networks. . However, due to the large-scale multi-load access to the distribu...
