“…The relatively sparse distribution of PMUs provides reliable coverage of system response with relatively high geographical resolution [1], [2]. Data gaps, the uneven distribution of the observations or sparse coverage, and differences in temporal resolution of dynamic recorders, among other factors, however, pose different kinds of difficulties that have to be addressed.…”

“…The recordings of this oscillatory event allow the examination of previously unrecognized sources of excitation of system modes and provide a new opportunity to observe and analyze a large inter-area oscillation involving all or most of the power system. Measured data from this event provide a useful complement to model-based detection methods in determining relevant operating limits and wide-area control systems in the MIS [1], [2].…”

On July 31st 2008 at 8:46 a.m. local time a combination of system events involving operational changes and a weak transmission system resulted in wide-spread system oscillations in the Mexican Interconnected System. The events were captured by the CFE wide-area measurement system and used to investigate various features of the observed oscillations.Following the event of July 2008, studies were conducted to analyze system dynamic behavior as well as to compare real power grid performance to predicted system models.This paper discusses the practical experience with the analysis of the observed data. Procedures for assessment and quantification of system motion are reviewed and improvements in modeling tools and techniques to characterize system oscillations are investigated and tested. Field experience gained from the readjustment of power system stabilizers is also described.Finally, challenges of incorporating wide-area measurements into proper real-time warning systems are addressed.Index Terms-Phasor measurement units, Wide-area measurement system, Interarea oscillations.

Power system oscillation damping remains as one of the major concerns for secure and reliable operation of large power systems, and is of great current interest to both industry and academia. The principal reason for this is that the inception of poorly-damped low-frequency inter-area oscillations (LFIOs) when power systems are operating under stringent conditions may lead to systemwide breakups or considerably reduce the power transfers over critical corridors. With the availability of high-sampling rate phasor measurement units (PMUs), there is an increasing interest for effectively exploiting conventional damping control devices, such as power system stabilizers (PSSs), by using these measurements as control input signals. In this paper, we provide a comprehensive overview of distinct elements (or "building blocks") necessary for wide-area power system damping using synchrophasors and PSSs. These building blocks together shape a tentative methodical framework, and are disposed as follows: (1) fundamental understanding of the main characteristics of inter-area oscillations, (2) wide-area measurement and control systems (WAMS and WACS) and wide-area damping control (WADC), (3) advanced signal processing techniques for mode property identification, (4) methods for model-based small-signal analysis, (5) control input signals selection, and (6) methods for PSS control design. We also describe the latest developments in the implementation of synchrophasor measurements in WAMS and WACS as well as their prospectives for WADC applications. This paper serves both to abridge the state-of-the-art in each of these elements, and to accentuate aspiring ideas in each building block.

“…A key element to achieve this goal is the wide area measurement system (WAMS), and more specifically the phasor measurement units (PMUs) or synchrophasors. Many PMUs have been installed in power systems around the world [3]- [7]. The PMUs were initially used for monitoring task, then were included in the area of protection, and recently are being incorporated in the control area.…”

Wide area monitoring systems (WAMS) together with phasor measurement units (PMUs) are the key to implement wide area control systems (WACS). WACS are responsible of achieving different control objectives from signals and measurements taken of a wide area network. Control objectives can be focused on a large region of the network or part of it. Furthermore, flexible ac transmission systems (FACTS) are devices that allow to implement the control laws designed and developed from measurements of WAMS/PMU. This paper presents a review of the current state of the art of WACS incorporating FACTS devices, specifically, the different FACTS configurations, applications and control used.Index Terms-Wide area control systems, wide area monitoring systems, flexible ac transmission systems, power system control, phasor measurement unit.
