The increasing demand of load without considerable increase in transmission resources has posed numerous constraints and challenges in the power system monitoring and performance. The inadequacy in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in...

In this paper, we present a structure for monitoring a large set of computational clusters. We illustrate methods for scaling a monitor network comprised of many clusters while keeping processing requirements low. A design for presenting high-level web-based summaries of the monitor network is provided, along with a generalization to a distributed, multipleresolution monitoring tree. Emphasis i...

With the guidance of Professor Wendi B. Heinzelman, he has researched wireless communications protocols with a major focus into wide area networking. iii Acknowledgements I would like to thank my Advisor on m...

In this paper, a novel neuro-fuzzy based method combined with a feature selection technique is proposed for online dynamic voltage stability status prediction of power system. This technique uses synchronized phasors measured by phasor measurement units (PMUs) in a wide-area measurement system. In order to minimize the number of neuro-fuzzy inputs, training time and complication of neuro-fuzzy ...

Low frequency power oscillations may be triggered by many events in the system. Most oscillations are damped by the system, but undamped oscillations can lead to system collapse. Oscillations develop as a result of rotor acceleration/deceleration following a change in active power transfer from a generator. Like the operations limits, the monitoring of power system oscillating modes is a releva...

Cyber security has become a critical priority for electric utilities. With the increase in the use of intelligent measuring devices like PMUs and more advanced communications and information technology in smart grid, the overall attack surface has increased. Cyber attacks against synchrophasor system critical infrastructure are detrimental to the functioning of the society as a whole. This pape...

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...

The <span>wide area monitoring system (WAMS) records and monitors every fault or disturbance that occurs in a power network using phasor measuring units (PMUs).
