Book Description :

Frequency Variations in Power Systems: Modeling, State Estimation and Control presents the Frequency Divider Formula (FDF); a unique approach that defines, calculates and estimates the frequency in electrical energy systems. This authoritative book is written by two noted researchers on the topic. They define the meaning of frequency of an electrical quantity (such as voltage and current) in non-stationary conditions (for example the frequency is not equal to the nominal one) and pose the foundation of the frequency divider formula. The book describes the consequences of using a variable frequency in power system modelling and simulations, in state estimation and frequency control applications. In addition, the authors include a discussion on the applications of the frequency divider in systems where part of the generation is not based on synchronous machines, but rather on converter-interfaced energy resources, such as wind and solar power plants. This important book: Offers a review that clearly defines and shows how the Frequency Divider Formula can be applied Discusses the link between frequency and energy in power systems Presents a unified vision that accurately reveals the common thread that links modelling, control and estimation Includes information on the many implications that “local frequency variations” have on power system dynamics and control Contains several numerical examples Written for researchers, academic staff members, students, specialised consultants and professional software developers, Frequency Variations in Power Systems questions the conventional transient stability model of power system and proposes a new formulation.

Book Description :

Growing system size and complexity along with the large amount of data provided by phasor measurement units (PMUs) are the drivers for accurate state estimation algorithms for online monitoring and operation of power grids. State estimation is the process of estimating unknown state variables in a power grid, which are then used for energy management system (EMS) functions in the control centre. Even with modern computing power, the large volume of computation in the state estimation process is highly time and memory intensive, and a serious bottleneck for online operation and control of the grid. Furthermore, the deployment of new smart grid technologies in communication and smart metering technologies brings new challenges to the state estimation problem. In addition to failure of physical infrastructure, the smart grid is also sensitive to cyber-attacks on its communication layer. Intelligent cyber-attacks can be designed to be unobservable by the traditional bad data detector. Such attacks can significantly impact the decision making process in control centres and can result in potentially catastrophic outcomes. The focus of this research is to design parallel computational algorithms to accelerate dynamic state estimation for both static and dynamic states in large-scale power networks. Moreover, a stochastic model is proposed to guard the system against intelligent cyberattacks. Utilizing the massively parallel architecture of graphic processors and using detailed models of power system components, the proposed research achieved the required accuracy as well as the computational speed-up in the results.

Book Description :

Decentralized Estimation and Control for Multisensor Systems explores the problem of developing scalable, decentralized estimation and control algorithms for linear and nonlinear multisensor systems. Such algorithms have extensive applications in modular robotics and complex or large scale systems, including the Mars Rover, the Mir station, and Space Shuttle Columbia. Most existing algorithms use some form of hierarchical or centralized structure for data gathering and processing. In contrast, in a fully decentralized system, all information is processed locally. A decentralized data fusion system includes a network of sensor nodes - each with its own processing facility, which together do not require any central processing or central communication facility. Only node-to-node communication and local system knowledge are permitted. Algorithms for decentralized data fusion systems based on the linear information filter have been developed, obtaining decentrally the same results as those in a conventional centralized data fusion system. However, these algorithms are limited, indicating that existing decentralized data fusion algorithms have limited scalability and are wasteful of communications and computation resources. Decentralized Estimation and Control for Multisensor Systems aims to remove current limitations in decentralized data fusion algorithms and to extend the decentralized principle to problems involving local control and actuation. The text discusses: Generalizing the linear Information filter to the problem of estimation for nonlinear systems Developing a decentralized form of the algorithm Solving the problem of fully connected topologies by using generalized model distribution where the nodal system involves only locally relevant states Reducing computational requirements by using smaller local model sizes Defining internodal communication Developing estimation algorithms for different models Applying the decentralized algorithms to the problem of decentralized control Demonstrating the theory to a modular wheeled mobile robot, a vehicle system with nonlinear kinematics and distributed means of acquiring information Extending the applications to other robotic systems and large scale systems Decentralized Estimation and Control for Multisensor Systems addresses how decentralized estimation and control systems are rapidly becoming indispensable tools in a diverse range of applications - such as process control systems, aerospace, and mobile robotics - providing a self-contained, dynamic resource concerning electrical and mechanical engineering.

Dynamic Phasor Estimation in Electrical Power Systems Based on IEC61850 Process Bus

Book Description :

State estimators in electrical power systems are implemented based on measurements that are provided by the SCADA systems or more recently, by dynamic phasor measurement units. The shortages of traditional SCADA systems such as the asynchronicity, the lack of using measurements with high sampling rates and complexity make them ineffective in capturing the dynamic response of a power system. Enhancing the performance of the state estimation by adding more dedicated phasor measurement units is costly. For reducing the cost and complexity of delivering measurements, IEC 61850 part-9-2 has been proposed using technology of Ethernet network communication. It uses a Process-Bus to link the equipment at switchyard and devices of protection and control at bay level. To enhance the phasor estimation and move from static to dynamic estimation, the high sampling rate of raw data provided by the Merging Unit as defined in IEC 61850 part-9-2 in combination with a Unscented Kalman filter as a dynamic estimator is proposed in the thesis. The major technical challenge that arises in applying Ethernet network communication is the impact of traffic performance on the estimated phasors and hence the substation protection and control reliability. This thesis work is to study the performance of proposed dynamic phasor estimator influenced by delay and/or loss of the Sampled Measured Value time critical messages over the Ethernet network communication. Detailed modelling of the Sampled Measured Value packet format and the IEC 61850 based digital communication are carried out using C programming language and TrueTime simulation tool is presented. To benefit from the raw Sampled Measured Values streamed with high sampling rate from Merging Units at substation process level, Unscented Kalman Filter Model-Based for dynamic phasor estimation is developed and proposed to be used at substation bay level in this thesis. To show how some protective relays can react to the proposed dynamic phasor estimation model under the IEC 61850-9-2 communication, an overcurrent protective relay is implemented based on the proposed dynamic phasor estimation and tested against different operation conditions of the IEC 61850 Process-Bus.
