Abstract:
Background: In order to better establish accurate load models and meet the practical
demand of current power system load modeling, it is necessary to establish related technical support
systems for power system load modeling.
Objective: The purpose of the paper was to construct the overall scheme of power system load
modeling technology support system and complete the development of the system.
Methods: Based on the modular design idea, the system adopts a multi-level architecture combining
B/S and C/S modes, covering the key technologies of substation classification based on selforganizing
neural network algorithm, load dynamic characteristic classification based on lifting
wavelet packet algorithm, load model parameter identification and load modeling based on adaptive
interactive multiple model (AIMM) algorithm.
Results: After actual operation verification, the built technology support system can well solve the
related problems of substation classification, load dynamic characteristic classification, load model
parameter identification and load modeling. It has the characteristics of a friendly man-machine interface,
simple operation and strong extensibility.
Conclusion: The built technology support system provides powerful technical support for improving
the load data management level of the power system and establishing an accurate load model,
and promotes the practical process of load modeling theory.
