this paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. an interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...

This paper presents an assessment of the vulnerability of the power grid to blackout using graph topological indexes. Based on a FERC 715 report and the outage reports, the cascading faults of summer WSCC 1996 are reconstructed, and the graphical property of the grid is compared between two cases: when the blackout triggering lines are removed simulating the actual sequence of cascading outages...

This paper has been inspired with the newly developed wide-area monitoring and control platform for power systems productised by ABB Switzerland Ltd. A benchmark problem for hybrid systems analysis and controller synthesis is reviewed here. All required signals can be obtained in practice from global phasor measurements available in real-time through the wide-area monitoring system. The aim of ...

The danger of a total blackout in wide area or, even worse, country is always present. restoration methods after mainly focus on the strategy that dispatchers control centers Transmission System Operator will follow than abilities distribution’s microgrids have. This study suggests technique to improve distribution system resilience following blackout, using distributed generation for important...

When disturbances occur in power grid, monitoring, control and protection systems are required to stop the grid degradation, restore it to a normal state, and hence minimize their effects. However, in wide area power grid resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the ov...

The optimal power flow based on available transfer capability proposed for contingent power systems. Generally, in power systems cost is the main objective. But in some areas cost is less importance such as under an emergency state of partial blackout. At that time transmission security is main objective. So, for transmission security, ATC is very useful. Maximizing ATC implies to reduce the pr...

The dynamics of power system blackouts and the associated Self-Organized Criticality (SOC) behavior is a subject that receives continuous attention in view of its inherent complexity and relevant consequences. Within this context, the paper focuses on the short-term dynamic and, more specifically, aims at studying the role of the spinning reserve and frequency control on the blackout mechanism....
