The prediction of post-disturbance frequency dynamic response plays a significant role in decision making for stability control. This paper proposes a feature extraction scheme for post-disturbance frequency prediction based on hierarchical agglomerative clustering (HAC). The post-disturbance dynamic response process of power system frequency is analyzed, on which the basic input features for pred...Show More
User behavior monitoring is an essential task in Zero Trust Network. In this paper, a semantic analysis framework is proposed to generate an integrated network user behavior which can be applied for abnormal detection. The framework first defines an unified network behavior structure which covers different network layers; then a knowledge graph of the network is created based on the entity detecti...Show More
