  • Patent number: 12284585
    Abstract: A cyber-physical integrated restoration method and system for distribution systems based on emergency mobile communications are provided. After extreme natural disasters which cause serious damage to distribution systems, damages of distribution systems are evaluated through system feedback data. When ground communication base stations are unavailable due to the damages, the method can make full use of existing wireless emergency communication resources to provide emergency communication services, and quickly restore the power supply through distribution automation functions with supports of the backup battery of automatic terminal devices, so as to effectively improve the resilience of distribution systems.

  • Publication number: 20210334658
    Abstract: The present disclosure provides a method for performing clustering on operation modes of a power system based on a sparse autoencoder. The method includes: obtaining related data of the power system; setting a training parameter, a number of hidden layers, and a number of neurons; training an autoencoder model using the related data and extracting a topological structure and a weight matrix from the model; performing cluster analysis to obtain a number of typical scenarios; and performing decoding to obtain original data at centers of respective scenarios. The present disclosure can achieve fast selection and dimensionality reduction of feature vectors representing operation modes of a power system. In view of this, the present disclosure provides a novel idea and method for selecting a feature vector representing an operation mode of a power system and generating a typical operation scenario.
