Secure State Estimation and Control for Cyber Security of the Nonlinear Power Systems
IEEE Transactions on Control of Network Systems, 2018We focus on securely estimating the state of a nonlinear dynamical system from a set of corrupted measurements for two classes of nonlinear systems, and propose a technique that enables us to perform secure state estimation for those systems. We then illustrate how the proposed nonlinear secure state estimation technique can be used to perform ...

Cyber security in power electronic systems
2021Grid-connected power electronic converters are crucial technologies that allow the electrical grid to interface renewable energy sources, energy storage systems, electrical vehicles, microgrids, and high-voltage DC transmission lines. As the number of power electronic converters in modern grids continues to grow, their monitoring and coordinated grid ...

The Role of Power System Visualization in Enhancing Power System Security
2014While the operation of much of the electric power grid is automated, the human operators and engineers are still very much “in the loop.” During times of emergency operation, when the system may be close to instability and collapse, having access to timely, pertinent information about a potentially rapidly changing system state could prove crucial in ...

Security Modelling for Power System Reliability Evaluation
IEEE Transactions on Power Systems, 2001This paper presents conceptual development, computation procedure and simulation results of the methodology for modelling security within reliability evaluation of power systems. The proposed approach takes into account activation of protection and automatic controls, local actions of operators, as well as centralized decisions taken by system ...

Security region analysis of power systems
6th International Conference on Advances in Power System Control, Operation and Management. Proceedings. APSCOM 2003, 2003This paper introduces the concept of extended dynamic security region (EDSR) to characterize the transient stability of power systems. Roughly speaking, if the present state of power system lies in the EDSR, the system maintains stability after experiencing disturbance.
