Abstract This paper presents a bibliographical review of definitions, classifications and applications concerning cyber attacks in networked control systems (NCSs) and cyber-physical systems (CPSs). This review tackles the topic from a control-oriented perspective, which is complementary to information or communication ones. After motivating the importance of developing new methods for attack detection and secure control, this review presents security objectives, attack modeling, and a character...

Online class imbalance learning constitutes a new problem and an emerging research topic that focusses on the challenges of online learning under class imbalance and concept drift. Class imbalance deals with data streams that have very skewed distributions while concept drift deals with changes in the class imbalance status. Little work exists that addresses these challenges and in this paper we introduce queue-based resampling, a novel algorithm that successfully addresses the co-existence of c...

This paper reviews several complex network theory-based methodologies to model and analyze interconnected networks. To address the deficiencies reported in past studies, an advanced model of coupled electric power system (EPS) and information and communication technology (ICT) is developed. The new model is designed as a 3-D graph with edges and nodes, and it highlights the interaction and interdependency of both EPS and ICT. The criticality of each component within the interconnected system is ...

For given system dynamics, observer structure, and observer-based fault/attack detection procedure, we provide mathematical tools – in terms of Linear Matrix Inequalities (LMIs) – for computing outer ellipsoidal bounds on the set of estimation errors that attacks can induce while maintaining the alarm rate of the detector equal to its attack-free false alarm rate. We refer to these sets to as hidden reachable sets. These bounds quantify the attacker's potential impact when it is constrained to s...

Cyber-enabled operation is needed for smart distribution system implementation. The interaction of cyber and power components will affect system reliability. This paper focuses on developing an analytical reliability model for fault detection, isolation, and service restoration for smart distribution feeders. The impact of end-to-end outage probability of data communication along with sending, receiving, and relaying communication node failures is incorporated into the model. Vulnerability of sy...

Abstract Critical Infrastructure Protection is a relatively new scientific domain stemming from an American Presidential directive PDD-63 of May 1998. Critical Infrastructure (CI) performance and protection are national priorities for all European Union (EU) countries following the introduction of the EU Directive 2008/114/EC, which takes an all hazards approach. This paper has an international focus. At the global and European level, the interest in identifying the impacts of climate change on ...

Abstract Condition monitoring is a crucial task for electromechanical system reliability and quality enhancement, which leads to early electrical and mechanical faults detection. In this paper, the design of a scaled test bench including its main subsystem components at initial stage is presented for the assessment of new methods dedicated to electrical and mechanical faults detection and diagnosis in electromechanical systems. In this paper a design methodology is proposed for developing a redu...

Wind power and Solar photovoltaic plants are expected to jointly produce a lion's share of renewable energy generation capacity needed to reach the target of having green energy around the globe. In this respect, investigation of voltage stability support and coordinated control are crucial step stones towards a future resilient power system. The ability to provide online voltage stability support from Renewable Generation plants highly depends on the communication infrastructure that allows an ...

AbstractThis paper proposes a reliability-based economic model predictive control MPC strategy for the management of generalised flow-based networks, integrating some ideas on network service reliability, dynamic safety stock planning, and degradation of equipment health. The proposed strategy is based on a single-layer economic optimisation problem with dynamic constraints, which includes two enhancements with respect to existing approaches. The first enhancement considers chance-constraint pro...

To have an accurate information of system states is always being a challenging task for the control designers irrespective the system is linear or non linear. This information is used for state feedback in tracking of a reference signal. An observer based optimal linear quadratic scheme is presented in this paper. Linear time invariant (LTI) system is used for reference tracking in the presence of external disturbance once only plant input and output is available to us. The proposed closed loop ...
