A hybrid simulation/measurement-based framework for online dynamic security assessment (DSA) is proposed in this work. It combines the strengths and features of simulation-based and measurement-based approaches to develop a tool that integrates the results and provides real-time situational awareness on available operating margins against major stability problems. High performance computing capability...
In the US power system, PhasorPoint was first used at ISO New England to provide monitoring and visualization of synchrophasor data. A comprehensive engineering analysis was then conducted by ALSTOM/Psymetrix on New England power system to fine tune the parameters used in oscillation and disturbance monitoring. The engineering analysis process is described in this paper and case studies are presented...
The modern power grid is one of the most complex engineering machines in existence. Its millions of components comprise the entire electricity supply chain, from point of generation to the end consumer. Each of these pieces must work together, reliably, 24 hours a day, seven days a week, to power our homes and businesses. In 2001, the U.S. National Academy of Engineering voted to recognize the grid...
We show how to combine together voltage angle phasor measurements at several buses to measure the angle stress across an area of the power system that is called a cutset area. The angle across the cutset area is a weighted average of the angles measured at buses at the borders of the cutset area. The angle across the cutset area is based on circuit theory and it responds to power flow through the...
