The capacity model of a load group mainly involves how to calculate and allocate the capacity in the load group to ensure the stability and reliability of the system. The following are several common load group capacity models and their application scenarios:
Load capacity linear model: This model assumes a linear relationship between the capacity of network nodes and the load, and proposes an ML model. The expression form of the model is

The betweenness centrality of a node represents the total number of shortest paths passing through that node. When nodes in the network fail, the load will be globally redistributed according to the shortest path strategy
Capacity model in psychology: In psychology, capacity model refers to some cognitive systems in the human brain with limited capacity, whose processing and storage of information are limited. This is similar to containers in daily life, where adding other things after the container is full can cause overflow. This model emphasizes the limited resources of the cognitive system and the limitations of information processing
CYME Integration Capacity Analysis Model: This model is mainly used for distribution systems, considering power quality and reliability, to determine the host capacitance of the distribution system. By using iterative methods to calculate the maximum power generation or load capacity of each point in the distribution system, the reliability and power quality of the system are ensured to be unaffected. This model is suitable for scenarios where the demand for distributed energy interconnection continues to increase, and can efficiently and consistently evaluate the system's power generation or load carrying capacity
Performance testing load model: In performance testing, load models such as waterfall model and fishbone model are used to ensure the stability and reliability of the system under different load conditions. The waterfall model provides load by adding a test object at regular intervals, making it suitable for scenarios where system issues are confirmed. The fishbone model covers all possible combinations of different load objects to comprehensively test the performance of the system
