This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates novel ways to utilize the potential of wide area synchrophasors for improved real-time monitoring and control of power systems. The performance of phasor measurement units (PMUs) was examined at the outset, since the accuracy and consistency of synchrophasor applications heavily rely on the input measurements. Two performance class algorithms: P-class and M-class, published in the IEEE standard C37.118.1-2011 were implemented on a commercial PMU and a simple test setup was developed to evaluate it. Tests revealed some inadequacies of the M-class algorithm and remedies were suggested. Moreover, several minor inconsistencies in error limits imposed by the existing synchrophasor standard were found and reported. Two new computationally efficient and stable algorithms for real-time estimation of transmission line parameters were developed. A third algorithm was developed to estimate parameters of series compensated lines. The proposed algorithms were validated through simulations carried out with a real-time digital simulator (RTDS), experiments conducted using a laboratory scale test setup, and using a set of field measurements. The second application is the prediction of transient stability status of a power system after a fault using synchrophasors. A novel algorithm, which utilizes the nature of rate of change of voltage vs. voltage deviation characteristics of the post-disturbance voltage magnitudes obtained from synchrophasors, was proposed. This algorithm is computationally simple and fast compared to the rotor angle based methods, capable of predicting the multi-swing transient instabilities, and pinpoints the generators that become unstable first, which is very useful for emergency controls. Offline and RTDS simulations demonstrated over 99% overall success rate under both symmetrical and asymmetrical faults, and robust performance under changes in pre-disturbance loading and network topology. Finally, a wide area response based emergency generator and load shedding scheme, which operates in conjunction with the prediction algorithm, was developed. A simple method to recognize the unstable cluster of generators using the synchronously measured voltages magnitudes is proposed and the unstable cluster is tripped if the system is predicted unstable. A frequency based load shedding scheme is applied to maintain the generation-load balance. The effectiveness of the approach was demonstrated using the RTDS based experimental test setup.

Download or read book On The Security of Wide Area Measurement System and Phasor Data Collection written by Kateb Reem and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Smart grid is a typical cyber-physical system that presents the dependence of power system operations on cyber infrastructure for control, monitoring, and protection purposes. The rapid deployment of phasor measurements in smart grid transmission system has opened opportunities to utilize new applications and enhance the grid operations. Thus, the smart grid has become more dependent on communication and information technologies such as Wide Area Measurement Systems (WAMS). WAMS are used to collect real-time measurements from different sensors such as Phasor Measurement Units (PMUs) installed across widely dispersed areas. Such system will improve real-time monitoring and control; however, recent studies have pointed out that the use of WAMS introduces significant vulnerabilities to cyber-attacks that can be leveraged by attackers. Therefore, preventing or reducing the damage of cyber attacks onWAMS is critical to the security of the smart grid. In this thesis, we focus our attention on the relation between WAMS security and the IP routing protocol, which is an essential aspect to the collection of sensors measurements. Synchrophasor measurements from different PMUs are transferred through a data network and collected at one or multiple data concentrators. The timely collection of phasors from PMU dispersed across the grid allows to maintain system observability and take corrective actions when needed. This collection is made possible through Phasor Data Concentrators (PDCs) that time-align and aggregate phasor measurements, and forward the resulting stream to be used by monitoring and control applications. WAMS applications relying on these measurements have strict and stringent delay requirements, e.g., end-to-end delay as well as delay variation between measurements from different PMUs. Measurements arriving past a predetermined time period at a data concentrator will be dropped, causing incompleteness of data and affecting WAMS applications and hence the system's operations. It has been shown that non-functional properties, such as data delay and packet drops, have a negative impact on the system functionality. We show that simply forwarding measurements from PMUs through shortest routes to phasor data collectors may result in data being dropped at their destinations. We believe therefore that there is a strong interplay between the routing paths (delays along the paths) for gathering the measurements and the value of timeout period. This is particularly troubling when a malicious attacker deliberately causes delays on some communication links along the shortest routes. Therefore, we present a mathematical model for constructing forwarding trees for PMUs' measurements which satisfy the end to end delay as well as the delay variation requirements of WAMS applications at data concentrators. We show that a simple shortest path routing will result in larger fraction of data drop and that our method will find a suitable solution. Then, we study the relation between cyber-attack propagation and IP multicast routing. To this extent, we formulate the problem as the construction of a multicast tree that minimizes the propagation of cyber-attacks while satisfying real-time and capacity requirements. The proposed attack propagation multicast tree is evaluated using different IEEE test systems. Finally, cyber-attacks resulting in the disconnection of PDC(s) from WAMS initiate a loss of its phasor stream and incompleteness in the observability of the power system. Recovery strategies based on the re-routing of lost phasors to other connected and available PDCs need to be designed while considering the functional requirements of WAMS. We formulate a recovery strategy from loss of compromised or failed PDC(s) in the WAMS network based on the rerouting of disconnected PMUs to functional PDCs. The proposed approach is mathematically formulated as a linear program and tested on standard IEEE test systems. These problems will be extensively studied throughout this thesis.
