“…The PMUs provide synchronized, real-time phasor measurements of voltage and current, generally augmented by measurement of frequency, rate of change of frequency, power and potentially other indirect measurements. PMUs providing such information have been used for different power system applications such system stability analysis, state estimation and wide area monitoring and control [1] [2].…”

Power Grid is facing a tremendous change characterized by many challenges. Future grid will definitely be a complex system hard to study, analyze and design with traditional, analytical and rule based approaches. In this context it is clear that in the design of future smart-grid, simulation in support of design and Hardware In the Loop methods will have a key role. In this paper we present the actual structure of the Automation of Complex Power System laboratory and future planned expansion to support the development of new automation concepts for future smart grid.

“…All the SIPS actions can be performed faster and more accurately by using PMU data in a wide area network rather than state estimated data. Wide area control addresses automatic healing capabilities by proposing decisive smart topology changes and control actions with the goal of maintaining the integrity of the grid under imminent, adverse conditions [17]. …”

The simulation of power system behavior, especially transient behavior, helps us in the analysis and planning of various power systems. However, power systems are highly complex and geographically distributed. Therefore system partitioning can be used to allow for sharing resources in simulation. In this work, distributed simulations of power system models have been developed using an electromagnetic transient simulator, namely Real Time Digital Simulator. The goal is to demonstrate and assess the feasibility of both non-real-time and real-time simulations using RTDS in a geographically distributed scenario. Different protocols and options used in the communication between power systems have been studied and analyzed. In this work, a test bed has been developed for data transfer between a power system simulated in RTDS at Mississippi State University and the power system simulated in RTDS at Texas A&M University.Finally, a locally distributed wide area control test bed was also developed and simulated.ii DEDICATION This thesis work is dedicated to my parents, my best friend Indira and my advisor.

“…Today's power systems operate closer to their security limits and have become more sensitive to failure occurrence due to a number of factors such as; the continuous growth in the electricity consumption, the environmental and the economic constraints for building up new transmission lines together with the growing number of independent power generators increasing the power systems generation (as a result of the deregulation and restructuring processes in the electric industry worldwide) [1][2][3][4][5]. Thus, the use of new technologies for the implementation of control actions as well as new control schemes have had to be considered with the aim of ensuring a secure and reliable operation of the power systems [1][2][3][4][5], turning the daily operation of today´s power systems more complex than ever before [6].…”

ABSTRACT:There is a typical dynamical performance associated with every system.Oscillations are phenomena inherent to dynamical systems and the analysis of such phenomena is a fundamental issue for understanding the dynamical behavior of a particular system. Knowledge of the system natural modes, frequencies and its associated damping ratio, provide valuable information regarding the system performance after being subjected to a disturbance. Due to the operational requirements, topological changes in the transmission network of the electrical power systems are quite common. This causes modification in both frequency and damping values of the natural system modes. In the past, normal changes in the operating condition have kicked up undamped power oscillations in the Mexican system, thus assessing the damping of critical oscillation modes of the system is of utmost importance. This paper reports on the application of modal analysis and time domain simulations for computing and tracking the most dominant low frequency oscillations, also known as interarea modes, in the Mexican power system under different operating conditions. As a result, the most influential system variables on the low frequency oscillations have been identified. RESUMEN:Existe un comportamiento dinámico típico asociado a todo sistema. Las oscilaciones son fenómenos inherentes a los sistemas dinámicos, por lo que el análisis de estos resulta fundamental para entender el comportamiento dinámico de un sistema en particular. El conocimiento de la frecuencia de oscilación y su correspondiente razón de amortiguamiento, asociados con los modos naturales del sistema, resulta fundamental para inferir el comportamiento dinámico del sistema después de que ha experimentado un disturbio. En un sistema eléctrico de potencia los cambios topológicos en la red de transmisión son bastante comunes debido a los requerimientos operativos. Esto ocasiona cambios en los valores tanto de la frecuencia de oscilación como el amortiguamiento de los modos naturales del sistema. En el pasado, cambios normales en la condición de operación del sistema mexicano han dado como resultado la aparición de oscilaciones de potencia no amortiguadas, por esta razón el conocer el amortiguamiento asociado con los modos críticos del sistema resulta de vital importancia. Este artículo reporta la aplicación del análisis modal y simulaciones en el dominio del tiempo para el rastreo de las oscilaciones de baja frecuencia dominantes, también conocidas como modos inter-área, en el sistema eléctrico mexicano durante diferentes condiciones de operación. Los resultados obtenidos permiten identificar a las variables del sistema de potencia más importantes sobre las oscilaciones de baja frecuencia.
