“…Moreover, studies on the vulnerability of a single type of cyber physical system are mainly carried out from the perspective of the electrical system at present. The impact of different types of load redistribution attacks on power cyber physical system is studied in [15,16], and vulnerability assessments are conducted. In [17], the vulnerability index of the power grid is given from four aspects.…”

With the continuous improvement of the informatization and intelligence of the Electrical and Thermal Cyber Physical System (ETCPS), the coupling between the various subsystems is getting closer and closer. When the system fails, due to the coupling characteristics, the system security risk is intensified. On this basis, the dual coupling characteristics of ETCPS have been analyzed according to the cyber physical model established first. Secondly, a two‐state optimal scheduling model and comprehensive vulnerability (CV) index, which consider various characteristics of ETCPS, are established, and interactions between the subsystems are analyzed quantitatively. Then, the source load loss rate is defined, which quantifies system security risk. Finally, five vulnerability assessment methods as well as the proposed method are compared. The feasibility and rationality of the proposed method are proved by two test systems.

“…On the other hand, weaknesses in communication protocols and schemes and network vulnerabilities can also be exploited by attackers to intrude into SCADA system to tamper with the data transformed between the units and the control center, and attackers can also employ man-in-the-middle attacks to deflect the data from their original values [19], [28]. Based on the above analysis and research [29], an attack mechanism schematic diagram of FDI attacks can be drawn as Fig. 1.…”

A topology attack, as a special class of false data injection attacks, tampers with topology information of a system to mislead the decision of the control center. This article conducts an in-depth study on topology attacks that aim to interfere with the judgment in topology information and pose potential damage by tampering with measurement data and protection information on branches, namely, protection-branch measurements-based topology attacks (PBT attacks). To achieve PBT attacks in actual networks, we study the protection settings and mechanisms in term of branches including transformers and transmission lines. Then, for the first time, we develop a bilevel model based on the protection configuration from the perspective of security-constrained economic dispatch. Meanwhile, since a bilevel model is constructed against dc state estimation, a conversion method in constructing attack vectors under PBT attacks against ac power system is proposed, which makes PBT attacks more suitable for actual power systems and more concealed. In a set of case studies on an IEEE 14-bus system, the simulation results verify the effectiveness of the model we proposed, analyze the vulnerability of network under PBT attacks, and then identify some critical branches that are defended to cope with PBT attacks. In addition, the comparison between PBT attacks and traditional cyber-overloaded attacks also shows a stronger threat of the studied attacks.

“…In other words, these actions are designed to prevent attackers from being able to launch cyber-attacks against power systems. The authors in [17]- [23] proposed various protection techniques, such as a blockchain-based framework to decentralize the data managing systems, stochastic game theory models to find the optimal way of protecting critical elements, and greedy algorithms to find protection strategies, which minimize the systems' vulnerabilities.…”
