This paper presents a framework to classify threats to power system secure operation. Threats have long been recognized; however, there lacks a categorical classification of them due to various individual perspectives from different organizations. The power system is evolving to a smart, super, and clean grid, accompanied by interior diversified and emerging threats. Furthermore, threats from exterior factors, intentional and non-intentional, conventional and new-born, to power systems have become more severe than ever before. Therefore, a distinct catalogue, description, and possible impact of these threats are proposed to meet the need of preventing power system from dangers. Using the proposed classification, a quantitative trend analysis of more than a hundred representative historic blackouts is performed to figure out the principal threats and the changing trend of threats over time. © 2013 Elsevier Ltd.

For a bounded Petri Net model the diagnosability property is usually checked via its regular language represented by the reachability graph RG. However, this is problematic because the computational complexity of the diagnosability test is polynomial in the cardinality of the state space of the model which is typically very large. This limitation can be overcome by using for the diagnosability test an ROF-automaton, with a state space significantly smaller than RG, that generates the same language as RG after projecting out all non-faulty unobservable transitions. ROFis efficiently constructed based on the calculation of the minimal explanations of the fault and of the observable transitions. © 2006 IEEE.

The protection of the national infrastructures is one of the main issues for national and international security. While FP7 MICIE project has proved that increasing cooperation among infrastructures increases their level of service and predictive capability, it is not enough to effectively counteract threats such as cyber attacks. Such attacks could be performed blocking communication from central SCADA to local equipments or inserting fake commands/measurements in the SCADA-field equipment communications (as happened with STUXNET worm). The paradox is that critical infrastructures massively rely on the newest interconnected (and vulnerable) ICT technologies, while the control equipment is typically old, legacy software/hardware. Such a combination of factors may lead to very dangerous situations, exposing systems to a wide variety of attacks. To overcome such threats, the CockpitCI project aims on one hand to continue the work done in MICIE by refining and updating the on-line Risk Predictor deployed in the SCADA centre, on the other hand to provide some kind of intelligence to field equipment, allowing them to perform local decisions in order to self-identify and self-react to abnormal situations induced by cyber attacks. It is mandatory to operate both at SCADA control centre and at field equipment because it is very dangerous to let field components operate autonomously. To address this issue an hybrid validation system will be implemented: at the Control Centre level an Integrated On-line Risk Predictor will provide the operator with qualitative/quantitative measurements of near future level of risk integrating data coming from the field, from other infrastructures, and from smart detection agents monitoring possible cyber attacks; at field level, the system is complemented with a smart software layer for field equipment and a detection system for the TLC network. The system will be validated on real equipment and scenarios provided by Israel Electric Corp.

PEGASE is a four year project dealing with the High and Extra High Voltage transmission and sub-transmission networks in Europe (designated as ETN) and implemented by a Consortium composed of 20 Partners including TSOs, expert companies and leading research centres in power system analysis and applied mathematics. Its overall objectives are to define the most appropriate state estimation, optimization and simulation frameworks, their performance and dataflow requirements to achieve an integrated security analysis and control of the ETN. The heart of the PEGASE project will involve advanced algorithmic, build prototypes of software and demonstrate the feasibility of real-time state estimation (SE), multi purpose constrained optimization (OPF) and time domain simulation of very large model representative of the ETN, taking into account its operation by multiple TSOs. Project R&D ambitions: The first ambition is to relieve all knowledge barriers to provide all TSOs with a synchronous display of the state of the ETN, very close to real time (typically each 5-10 seconds). The second ambition is to develop OPF programs determining realistic system operating points that include TSO operating rules but also optimal preventive or corrective actions, typically for real-time congestion management. The third ambition is to improve the existing state of the art technology in time simulation of very large system to permit: i/ off-line studies of the ETN including possibly interconnections with neighboring systems (i.e. Russia), ii/ dispatcher training simulation iii/ preventive security assessment and in on-line emergency conditions, faster than real-time simulation opening new perspectives for an anticipative control of the system. Project expected impacts: The availability of duly tested prototypes will allow for a quick implementation of the developed tools in a central facility and in existing computing environments. A better management of crisis will allow decreasing conservative security margins and improving the identification of real risks. Operating with higher power flows and closer to real available transfer capacities determined more transparently from the shared real-time model will enhance the cross-border electricity market. Eventually, the first European dispatcher training simulator will be at arm length for use in a European training center allowing the simultaneous training of dispatchers from several countries that is the cornerstone of the integrated operation of the ETN.
