“…In (Rice et al, 2008), state estimation uses measurements to obtain important power system operating information ("states"). Tiwari et al (2007) treated the operating state of power system changes dynamically due to severe change in system conditions such generation, load or line trip. Such severe disturbances effect voltage phasor, current phasor and system frequency.…”

“…A characteristic ellipsoid (CELL) method to monitor the power system dynamic behavior and provide wide-area situational awareness using PMU data is presented in [14]. A logic-based method to identify a contingency severity and to assess voltage stability from PMU data is proposed in [15]. A vulnerability assessment method for quickly assessing the post-contingency status of a multi-area power system, using PMU data and Wide Area Severity Indices (WASI), is developed in [16].…”

In recent years, some Smart Grid applications have been designed in order to perform timely Self-Healing and adaptive reconfiguration actions based on system-wide analysis, with the objective of reducing the risk of power system blackouts. Real time dynamic vulnerability assessment (DVA) has to be done in order to decide and coordinate the appropriate corrective control actions, depending on the event evolution. This paper presents a novel approach for carrying out real time DVA, focused on Transient Stability Assessment (TSA), based on some time series data mining techniques (Multichannel Singular Spectrum Analysis MSSA, and Principal Component Analysis PCA), and a machine learning tool (Support Vector Machine Classifier SVM-C). In addition, a general overview of the state of the art of the methods to perform vulnerability assessment, with emphasis in the potential use of PMUs for post-contingency DVA, is described. The developed methodology is tested in the IEEE 39 bus New England test system, where the simulated cause of vulnerability is transient instability. The results show that time series data mining tools are useful to find hidden patterns in electric signals, and SVM-C can use those patterns for effectively classifying the system vulnerability status.

Abstract-Nowadays the increase of power electronic devices at the distributed side, which has ability to provide power factor correction and reactive power control at the same end. The device connect to distributed side are resonant converter, saticVar co mpensator, power buffer, solar panels, and pluggable hybrid electric vehicles (PHEVs ),Such equip ment are not presently utilized by the power system to fulfill the react ive power for unity voltage profile. The integration of these enduser RCD are done to support the grid via a secure communicat ions infrastructure.The real t ime data of bus system measured by PMU and transfer to control center through GPS system. PMU and SCADA measurement data can be displayed in the same line monitoring and displaying on power substations. Ttraditionally the un-authentic communicat ion network has used via fiber-based networks, cellu lar netwo rk, Wi-Fi and Wi-Max networks as well as more ad-hoc radio and wireless mesh networks .in this paper the new communicat ion network with authentic signature is suggested and also the optimal p lacement of PM Us Due high cost.
