System Integrity Protection Schemes for enhanced security and capacity
System Integrity Protection Schemes (SIPS) are in use to increase secure power transfer in regions or cases where N-1 operation cannot be maintained. Utilization of PMU data in the development and deployment of solutions, enable SIPS to become response-based and thus providing increased security for a broader range of scenarios

Perception, Prediction and Prevention of Extraordinary Events in the Power System
Conventional risk and reliability assessment techniques are insufficient when it comes
to analysing extraordinary events on-line. The reason for this lies in the nature of
extraordinary events, which are the result of dependent or multiple failures leading to an
unstable operation. Thus, novel and unconventional techniques are required to analyse
and quantify the risk related to extraordinary events.
This thesis describes advances regarding perception, prediction, and prevention of
extraordinary events. The focus of this work has been on the operation of the power
system, where prediction and prevention of extraordinary events are required on-line
and in the day-ahead operation planning.
A central part of the perception of extraordinary events lies in the identification of the
transition from a stable to an unstable state being a fundamental and critical
characteristic of extraordinary events. Together with the realisation that situational
awareness is a requirement for the implementation of remedial actions, this provides a
basis for the development of solutions to predict and prevent extraordinary events. A
methodology for analysing extraordinary events is presented in this thesis, identifying
the requirement to perform transient dynamic multi-level contingency studies to
properly address the risk of extraordinary events.
Measures to improve the situational awareness are presented, in form of vulnerability
indicators. These measures are of both a predictive and preventive nature, with
vulnerability indicators supporting the operator to predict the risk of extraordinary
events providing a decision base regarding implementation of manual preventive
actions. Furthermore, a concept to assess the transfer capacity of critical power transfer
corridors is presented. This concept is proposed to be utilised in the development of
automatic controls, to prevent extraordinary events through appropriate mitigating
actions.
The predictive and preventive measures presented in this thesis describe conceptual
solutions for decreasing the risk of extraordinary events. These measures depend on
further development of tools and techniques in order to be integrated in, and supportive
for, the tools used for operating the power system
