These slides focus on preliminary discussions about wide area monitoring, protection and control in future smart grid. Later in the class i will show its application through simulation and case study results.
The modern-day power grid aims at providing reliable and quality power, which requires careful monitoring of the power grid against catastrophic faults.

Reliability analysis of pmu using hidden markov modelamaresh1234
As modern electric power systems are transforming into smart grids, real time wide area monitoring system (WAMS) has become an essential tool for operation and control. With the increasing applications of WAMS for on-line stability analysis and control in smart grids, phasor measurement unit (PMU) is becoming a key element in wide area measurement system and the consequence of the failure of PMU is very severe and may cause a black out. Therefore reliable operation of PMU is very much essential for smooth functioning of the power system. This thesis is focused mainly on evaluating the reliability of PMU using hidden Markov model. Firstly, the probability of given observation sequence is obtained for the individual modules and PMU as a whole using forward and backward algorithm. Secondly, the optimal state sequence each module passes through is found. Thirdly, the parameters of the hidden Markov model are re-estimated using Baum-Welch algorithm.
Joint State and Parameter Estimation by Extended Kalman Filter (EKF) techniqueIJERD Editor
In order to increase power system stability and reliability during and after disturbances, power grid
global and local controllers must be developed. SCADA system provides steady and low sampling density. To
remove these limitation PMUs are being rapidly adopted worldwide. Dynamic states of power system can be
estimated using EKF. This requires field excitation as input which may not available. As a result, the EKF with
unknown inputs proposed for identifying and estimating the states and the unknown inputs of the synchronous
machine.
Voltage Stability Assessment using Phasor Measurement Units in Power Network ...Satyendra Singh
This paper presents the assessment methodology for
voltage stability using Phasor Measurement Unit (PMU) with
complete system observability. For full power system
observability, the PMU placement is considered with and without
conventional power flow as well as injection measurement such
that minimum number of PMU’s is used. Data obtained by
PMU’s are used for voltage stability assessment with the help of
L-Index. As the PMU gives real time voltage and current phasors
and L-index is dependent on voltage and admittance values, thus
the L-index so obtained can be used as real time voltage stability
indicator. The case study has been carried out on IEEE-14 bus
system.
There is rapidly-growing industry interest in the potential uses for streaming synchronized measurements from Phasor Measurement Units (PMUs). Vendors and users continue to develop and deploy new applications and infrastructure to take advantage of the new measurement data. San Diego Gas & Electric Company (SDG&E) is among users who are deploying Wide-Area Situational Awareness (WASA) systems in which PMUs distributed across the grid are streaming data to control centers for situational awareness of dynamic wide-area behavior of the grid to system operators, and as a tool for engineers to perform post-event analysis of disturbances and operating events along with system model validation. These uses are just a part of a broader roadmap for many important new applications using PMU measurements. Over time, synchrophasors will serve as the new unified wide-area data-gathering platform serving system observation, operating data collection for SCADA and EMS, control, automation, market functions, asset management and maintenance support, and even high-speed wide-area fault and failure protection functions that supplement and back up local fault protection. A full-function PMU-based deployment is described as a Wide-Area Monitoring, Protection, Automation, and Control (WAMPAC) system.
The paper reviews the applications of operator situational awareness, SCADA and EMS data gathering, disturbance monitoring and analysis with model tuning, system state and condition monitoring, adaptive RAS, fire and hazard risk reduction, wide-area backup fault protection and swing mitigation, wide-area voltage stability monitoring and mitigation, wide-area voltage control, and PMU system self-monitoring. It characterizes the key elements and architecture of a wide-area PMU system from the PMUs through communications networks with redundancy and timing services to centralized processing locations or clouds.

Phase Measurement Units based FACT’s Devices for the Improvement of Power Sys...IJECEIAES
This paper describes the importance of FACTS devices; it presents the outcome of the study of its reflectance on the performance of power system networks. It seeks to increase and guarantee the fact and accuracy of response systems under disturbance conditions when the phase measurement units are introduced as Real-Time Measurement (RTM) stations. This paper also describes the importance of FACTS devices. The combination of FACTS devices and PMUs is presented to increase the controllability performance of power systems. This paper demonstrates how PMUs measure voltage, current and their angles. It provides, through a communication link, a Phase Angle Data Concentrator (PDC) to make an appropriate decision to correct the power system state using the FACTS device (TCSC). We utilized the Graph-Theoretic Algorithm to optimize the number and location of PMUs. The technique proposed was tested on the Iraqi National Super Grid’s 24bus network, Diyala City’s regional 10bus network and the 14bus IEEE standard test system. The MATLAB/PSAT package was utilized for the simulation of results. It is evident that our proposed algorithm and technique achieved the purpose of this paper as confirmed by the level of accuracy of the results obtained from most of the cases tested.
Real Time Dynamics Monitoring System (RTDMS): Phasor Applications for the Co...Power System Operation
The electric power grid in the US has evolved
from a vertically integrated system to a mixture of
regulated and deregulated competitive market system.
Grid oversight is transitioning from local utilities to an
assortment of transmission companies, regional
Independent System Operators (ISOs) and Regional
Transmission Organizations (RTOs). Regulatory and
economic pressures have caused new transmission
construction to lag the growth in demand. These forces
have increased pressure on electricity markets and
caused operators to maximize the utilization of the
system. The result is an operating environment where
operators are faced with quick changing and previously
unseen power flow patterns and operational conditions
with limited information available for real-time
operation and decision-making. Furthermore, the aging
