This paper studies an extended formulation of the security constrained optimal power flow
(SCOPF) problem, which explicitly takes into account the probabilities of contingency events …

This paper proposes a classification of reliability criteria for power systems based on four
characteristics:(i) the set of considered system states,(ii) the objective function,(iii) the …

Major blackouts may have critical societal consequences and are very challenging to
analyse and mitigate. Part of the challenge lies in the complex sequences of events that …

High-Impact Low-Probability (HILP) events in power systems historically involve a multitude
of aspects, including diverse and disparate threats, failures and sequences of events. Each …

Large power-infeed of individual HVDC interconnectors may make the power system
vulnerable to contingencies involving multiple HVDC interconnectors. This paper describes …

Individual HVDC links connecting the Nordic power system to other synchronous systems
may carry gigawatts of power. For the transmission system operators, who must maintain …

Recent advances in IT-related fields are opening up a broad range of novel applications.
This is especially true in the energy sector, where Smart Grid solutions are offering new …

This paper proposes a methodology for assessing the risk implied by the potential failure of
post-contingency corrective controls. We express such risk in terms of service interruption …

Power system operation is concerned with supplying electricity to society in a reliable
manner. Reliability has traditionally been managed through use of the deterministic N-1 …

Society is dependent on a reliable electricity supply for its normal operation. Blackouts can
have severe societal consequences and are sometimes termed extraordinary events. These …
