Over the past decade, the cyber security of power systems has been widely studied. Most previous studies have focused on cyber physical attacks, and barely considered one typical cyber attack: availability attack. We propose a hybrid attack model and apply conventional state estimation processes to study cyber attacks on power grids in this paper. The proposed model considers both integrity attack and availability attack simultaneously. Compared with the particular attack, namely, false data injected attack, we analyze their consequences to power systems in the events of false negatives attack and false alarm attack. The results show that the hybrid attack can confuse the control center by manipulating the integrity and availability of measurements. More importantly, we evaluate the hybrid attack with different values of the cost ratio between integrity and availability attacks, and then verify that the hybrid attack can achieve the same goal with a reduced cost.

“…Also, load frequency control was studied by a coordinated attack model in [24]. In response to the huge threat of cyber-physical attacks, many researchers have proposed corresponding countermeasures [25], [26]. However, the above coordinated attacks do not consider the availability attacks.…”

“…With the rapid development of networking, computing, intelligence and modern control, cyber‐physical systems (CPSs) have generated considerable research interest in the past few years. CPSs deeply integrate information systems with physical systems, and have a wide range of applications in smart grids, 1,2 industrial manufacture, 3 aerospace, 4 and intelligent transportation 5 . However, due to the use of wireless networks, CPSs are vulnerable to cyber‐attacks 6‐8 …”

This article studies the optimal filtering problem for cyber‐physical systems under stealthy hybrid cyber‐attacks. Due to the stealthiness of cyber‐attacks, the optimal filter (OF) consists of an exponentially increasing number of terms, which makes it computationally infeasible in practice. To address this computational issue, an optimal linear filter (OLF) is developed with its estimation performance fairly close to the optimal one. Furthermore, for a system under the stealthy hybrid cyber‐attacks, it is proved that when the system is stable, the exponentially increasing number of terms remain bounded, making the OF stable; and that the OLF is stable if and only if the system is stable. Finally, numerical examples are employed to illustrate the effectiveness of the proposed two filters.

“…To achieve secure consensus control of MASs, some resilient continuous‐time transmission or periodic sampling transmission cooperative control frameworks have been proposed 16‐18 . For example, Tian et al 19 considered the coordinated control of a smart grid system under DoS attacks. In Reference 20, the authors investigated the resilient control problem for constrained linear MASs with bounded disturbances and DoS attacks by a sampled‐data robust model predictive control approach.…”

Event‐based resilience to DoS attacks on communication for consensus of networked Lagrangian systems

Summary In this article, we consider the resilience analysis of the even‐based consensus control of networked Lagrangian systems under denial‐of‐service (DoS) attacks, which are usually implemented by the attackers to block the communication channels. Comparing with the linear cyber‐physical systems, the secure control of the networked Lagrangian systems is more complex and challenging, especially under the conditions of asymmetry communication and discontinuous control. To this end, an event‐based controller is first designed for consensus control of networked Lagrangian systems in the absence of DoS attacks. Sufficient conditions are given to stabilize the closed‐loop systems. Then the resilience analysis is presented for the event‐based controller under DoS attacks. Some conditions associated with the DoS duration and frequency are proposed for the control parameters against the attacks. Then Zeno behaviors are proved to be nonexistent in the proposed control scheme. An algorithm is also given to guide the control design.
