Available in PDF, EPUB and Kindle. Book excerpt: State Estimation for Dynamic Systems presents the state of the art in this field and discusses a new method of state estimation. The method makes it possible to obtain optimal two-sided ellipsoidal bounds for reachable sets of linear and nonlinear control systems with discrete and continuous time. The practical stability of dynamic systems subjected to disturbances can be analyzed, and two-sided estimates in optimal control and differential games can be obtained. The method described in the book also permits guaranteed state estimation (filtering) for dynamic systems in the presence of external disturbances and observation errors. Numerical algorithms for state estimation and optimal control, as well as a number of applications and examples, are presented. The book will be an excellent reference for researchers and engineers working in applied mathematics, control theory, and system analysis.

Book excerpt: With the increasing complexity resulting from uncertainties and stochastic variations introduced by intermittent renewable energy sources, responsive loads, mobile consumption of plug-in vehicles, and new market designs, more and more dynamic behaviors are observed in everyday power system operation. To operate a power system efficiently and reliably, it is critical to adopt a dynamic paradigm so that effective control actions can be taken in time. The dynamic paradigm needs to include three fundamental components: dynamic state estimation; look-ahead dynamic simulation; and dynamic contingency analysis (Figure 1). These three components answer three basic questions: where the system is; where the system is going; and how secure the system is against accidents. The dynamic state estimation provides a solid cornerstone to support the other 2 components and is the focus of this study.

Book excerpt: Research in the area of power system transient stability has recently focused on dynamic state estimation using high rate Phasor Measurement Unit (PMU) data. Several mathematical models for synchronous machine are developed and various estimation approaches are proposed for this purpose. In this thesis, the mathematical formulation of nonlinear state space modeling and the principles of Kalman Filter are explained. Extended and Unscented Kalman Filters (EKF and UKF), as two nonlinear estimation methods, are applied for state and parameter estimation in an induction motor. In the next stage, after presenting a thorough explanation about modeling of the synchronous machine, dynamic state estimation is applied on different power system case studies and the results of estimation methods are compared. The simulation results provided in this thesis show the great potential of the proposed estimation approaches for accurately estimating the states of the machine as well as reducing the effect of noise on input signals.

Download or read book Holomorphic Embedded State Estimation for AC DC Power Systems written by Shaun Mendoza Cruz and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The desire for more autonomous and resilient architectures coupled with the increased inclusion of power electronics is shifting the topology of power systems to be more integrated alternating current (AC) and direct current (DC) where AC dominance can no longer be assumed. Because of the unique physical and mathematical properties of AC-DC power systems, existing tools for power system development and operation may require modification and/or a new approach may be warranted. Issues encountered by AC-DC power systems will require the development of new and practical tools, analyses, and algorithms. State estimation is a key component in the operation and control efforts of power systems. The objective of state estimation is to provide an estimate of the complex voltages values at all buses for a power system, given redundant measurements of varying accuracy. The traditional approach to solving the static state estimation problem is to utilize a non-linear weighted least squares approach solved via iterative methods. Traditional AC-DC state estimation methods will be more prone to convergence issues as the amount of DC subsystems increases and system stability is stressed due to larger and more dynamic loads. This work proposes a non-iterative approach to the static state estimation problem applied to AC-DC power systems. Specifically, it details the development of the Holomorphic Embedded State Estimation (HESE) method. By employing a holomorphic embedding approach, the state estimation problem is framed in the field of complex analysis and analytic continuation. By taking advantage of strategic complex embedding and features of holomorphic functions, a non-iterative state estimator is developed which does not inherit the convergence issues derived from the nature of iterative solvers. The results of the HESE method applied to a physical AC power system, simulated DC power system, and simulated AC-DC converter is discussed. Finally, results of the application of the HESE method to a simulated AC-DC power system in a sequential and unified fashion is discussed.
