“…The first case is a three-phase fault at bus 54 which is between two groups of coherent generators. This fault initiates the inter-area oscillations [32,34], which may result in instability due to either the first-swing or multi-swing oscillations. The CCTs obtained from the time-domain simulation and PEBS are 0.098 and 0.106 s, respectively, and the critical energy is 2.904 pu.…”

“…This section briefly describes the principles of H∞ control used in the design of the WADC. Robust control techniques based on H∞ methods have been previously used to design WADCs in the literature [7,13,45]. For a linear system with transfer function E(s), its H∞ norm is the highest gain of the transfer function over all frequencies and input directions [46].…”

The cyber-physical nature of electric power systems has increased immensely over the last decades, with advanced communication infrastructure paving the way. It is now possible to design wide-area controllers, relying on remote monitor and control of devices, that can tackle power system stability problems more effectively than local controllers. However, their performance and security relies extensively on the communication infrastructure and can make power systems vulnerable to disturbances emerging on the cyber side of the system. In this paper, we investigate the effect of communication delays on the performance and security of wide-area damping controllers (WADC) designed to stabilise oscillatory modes in a Cyber-Physical Power System (CPPS). We propose a rule-based control strategy that combines wide-area and traditional local stabilising controllers to increase the performance and maintain the security of CPPS. The proposed strategy is validated on a reduced CPPS equivalent model of Great-Britain (GB).

“…We can now apply the error correction method introduced in Section II to the linearized system in (15) and reconstruct x(0) if we satisfy the condition in Lemma 2. Next, we consider an interconnected power system with several synchronous generators, and illustrate how the proposed nonlinear state estimation approach can be applied for the secure state estimation of practical systems.…”

“…Clearly, the greater dependence on communication systems increases opportunities for cyberphysical attacks and disturbances. Extensive work has been done on monitoring and on autonomous feedback control for WACS [15], but this work has not studied how to identify cyber-physical attacks or communication failures, and how to perform secure state estimation for WACS. In this paper, we focus on secure estimation for the wide area control of an interconnected power system, and assume that the system operator has installed several phasor arXiv:1603.06894v1 [cs.SY]…”

This paper focuses on securely estimating the state of a nonlinear dynamical system from a set of corrupted measurements. In particular, we consider two broad classes of nonlinear systems, and propose a technique which enables us to perform secure state estimation for such nonlinear systems. We then provide guarantees on the achievable state estimation error against arbitrary corruptions, and analytically characterize the number of errors that can be perfectly corrected by a decoder. To illustrate how the proposed nonlinear estimation approach can be applied to practical systems, we focus on secure estimation for the wide area control of an interconnected power system under cyber-physical attacks and communication failures, and propose a secure estimator for the power system. Finally, we numerically show that the proposed secure estimation algorithm enables us to reconstruct the attack signals accurately. which use the synchrophasor technology to maintain the system's stability. WACS employ advanced data acquisition, communications, and control to enable increased efficiency and reliability of power delivery [12]- [14]. While WACS are the most promising technology to detect small signal instabilities in large power systems, their performance is highly dependent on the received data and on the underlying communication network. Clearly, the greater dependence on communication systems increases opportunities for cyberphysical attacks and disturbances. Extensive work has been done on monitoring and on autonomous feedback control for WACS [15], but this work has not studied how to identify cyber-physical attacks or communication failures, and how to perform secure state estimation for WACS. In this paper, we focus on secure estimation for the wide area control of an interconnected power system, and assume that the system operator has installed several phasor arXiv:1603.06894v1 [cs.SY]
