Modeling and Formulation of Delayed Cyber-Physical Power System for Small-Signal Stability Analysis and Control

Modeling of Time-Delayed Distributed Cyber-Physical Power Systems for Small-Signal Stability Analysis

“…x y (12) Notably, unlike the model for centralized control mode in [15], the power system in distributed control needs to consider not only the local measurement delay and execution delay but also the communication delays between different agents; thus, we establish the abovementioned distributed information flow model. As stated in the general model of a dynamic power system, the power flow equation is memoryless.…”

Observer‐Based Sensor Attack Diagnosis for Cyber‐Physical Systems via Zonotope Theory

“…In view of practical points, CPSs are widely used in intelligent transportation [1,2], smart grid [3][4][5][6], environmental monitoring [7,8] and so on. CPSs have obtained much attention recently, in which various problems such as secure state estimation [9][10][11][12][13][14][15][16][17], stability analysis [18][19][20][21][22] and fault detection [23][24][25][26][27] have been addressed. For example, the state and attack estimation problems for CPSs under actuator and sensor attacks and the disturbances have been investigated in [10].…”

“…[15] provides an estimator for a CPS with limited communication resources, sensor saturation and denial-of-service attacks. In [20], the stability for a delayed cyber-physical power system is enhanced by combing with presented delay emerge properties. [26] proposes an attack detection scheme using Kalman filter through residual-based attack detection procedures.…”
