We study the interdependency between the power grid and the communication network
used to control the grid. A communication node depends on the power grid in order to …

In complex networks, different nodes have distinct impact on overall functionality and
resiliency against failures. Hence, identifying vital nodes is crucial to limit the size of the …

Due to the rapid deployment of phasor measurement units (PMUs) on large power grids, the
system operators now have access to high speed high resolution data. A new class of …

Security assessment is among the most fundamental functions of power system operator.
The sheer complexity of power systems exceeding a few buses, however, makes it an …

Intentional islanding of a power system can be an emergency response for isolating failures
that might propagate and lead to major disturbances. Some of the islanding techniques …

In a bulk power system, generators can be divided into groups based on the variation of their
swing curves after disturbance occurrence. In this regard, generators that have the same …

The increasing integration of renewables into the grid based on power electronics
converters interfaces is affecting the power systems dynamics, requiring effective monitoring …

Since phasor measurement units (PMU) were invented, there has been growing interest in
developing methodologies for improving monitoring, protection and control of power …

System restoration from cascading failures is an integral part of the overall defense against
catastrophic breakdown in networked critical infrastructures. From the outbreak of cascading …

Cascading outages leading to large-area blackouts can be mitigated using intentional
controlled islanding (ICI). An ICI scheme must define the most suitable time to split the …
