This book reviews and examines how power system low-frequency power oscillations and sub-synchronous oscillations may be affected by grid connection of wind power generation. Grid connection of wind power generation affects the power system small-signal stability and has been one of the most actively pursued research subjects in power systems and power electronics engineering in the last ten years. This book is the first of its kind to cover the impact of wind power generation on power system low-frequency oscillations and sub-synchronous oscillations. It begins with a comprehensive overview of the subject and progresses to modeling of power systems and introduces the application of conventional methods, including damping torque analysis, modal analysis and frequency-domain analysis, presented with detailed examples, making it useful for researchers and engineers worldwide.

Power System Small Signal Stability Analysis and Control presents a detailed analysis of the problem of severe outages due to the sustained growth of small signal oscillations in modern interconnected power systems. The ever-expanding nature of power systems and the rapid upgrade to smart grid technologies call for the implementation of robust and optimal controls. Power systems that are forced to operate close to their stability limit have resulted in the use of control devices by utility companies to improve the performance of the transmission system against commonly occurring power system disturbances. This book demonstrates how the application of power system damping controllers such as Power System Stabilizers (PSSs) and Flexible Alternating Current Transmission System (FACTS) controllers—namely Static Var Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC)—can guard against system disruptions. Power System Small Signal Stability Analysis and Control examines the signal stability problem, providing an overview and analysis of the concepts and of the controllers used to mitigate it. Detailed mathematical derivations, illustrated case studies, the application of soft computation techniques, designs of robust controllers, and end-of-chapter exercises make it a useful resource to researchers, practicing engineers, and post-graduates in electrical engineering. Examines the power system small signal stability problem and various ways to mitigate it Offers a new and simple method of finding the optimal location of PSS in a multi-machine power system Provides relevant exercises to further illustrate chapter-specific content

This book provides a systematic introduction to power system sub/super-synchronous oscillations caused by grid-connected wind power generation. The authors look at why oscillations occur and present methods for examining the risk of oscillations. Coverage includes state-space model based analysis and impedance model based analysis, which are the two main methods for examining the power system sub/super-synchronous oscillations. In addition, new methods for examining oscillations in wind farms are proposed. Analysis of Power System Sub/Super-Synchronous Oscillations Caused by Grid-connected Wind Power Generation provides researchers and students with a single-volume introduction to the subject and will be a valuable professional reference for practicing engineers looking for solutions to oscillation problems.

Synchronous generator stability is an essential issue in the studies of dynamic performance of electric power systems. One important category of stability analysis is the low-frequency oscillations of machine rotor due to disturbances to which the power system is susceptible. These oscillations may sustain and grow in magnitude to cause machine separation if adequate damping is not provided. To enhance system damping, the generating unit is equipped with a power system stabilizer (PSS). Conventional PSS's are widely utilized to damp the low-frequency inertial oscillations. The design of such stabilizers involves finding the set of PSS parameters which yield the best achievable damping response. Several design approaches were proposed over the years and some of them are given in the literature review of this study. A novel genetic-algorithm based optimization approach to design a robust PSS is presented in this study. The proposed approach employs optimization of damping to obtain minimum speed deviation and best possible time-domain transient performance. The single machine infinite bus system is used in this work. Simulations of the linearized system in addition to a simpower model based on the SimPowerSystems(r) are presented. The machine speed response has been investigated for both models in the case of Classic-PSS and GA-PSS designs. Their results are compared at different operating conditions, and the comparison shows that the proposed method gives encouraging results against classic method based on system response while being subjected to disturbances which mean that the system maintains its stability during ( 20 %) of perturbations in the load or the system is robustly stable."

The environmental and economic impact of fossil fuel generating plants has resulted in the need to find more efficient and clean sources of electricity power generation. As an alternative, promising power generation options such as renewable energy sources, especially wind energy, are receiving increased interest. This dissertation addresses some important problems in power system operations (stability and power quality) when renewable energy resources (generation and storage) are integrated into the conventional power system. In particular, the use of energy storage (STATCOM/Battery) to enhance the small-signal stability, transient stability, and voltage regulation of an electrical power system with renewable power generation is investigated as follows. 1) A linearized model of the nonlinear power system in the region of a steady-state operating point is used in conjunction with an LMI-based control design method, including D-stability, to achieve small-signal angle and frequency stability, voltage regulation, when the system is perturbed by changes in mechanical power inputs to the synchronous generators in the system. 2) A nonlinear model of the power systems with energy storage is used with an Interconnection and Damping Assignment-Passivity-Based Control design (IDA-PBC) framework to achieve transient power angle stability along with frequency and voltage regulation after the occurrence of a large disturbance (a symmetrical three-phase short circuit transmission line fault). 3) Using the combination of the IDA-PBC control law and a reduced-order nonlinear observer, voltage regulation and system stability enhancement are simultaneously accomplished following both temporary and permanent faults. To illustrate the effectiveness of the STATCOM/Battery to enhance small-signal and transient stability, the LMI-based controller design with D-stability and IDA-PBC controller design are validated using the following simulation studies: (1) a single machine infinite bus (SMIB) (2) a two-machine (synchronous generator and doubly-fed induction generator) connected to an infinite bus. For the small-signal case, simulation results show that the proposed controller can simultaneously achieve frequency and voltage regulation along with improved transient performance. For the large-signal case, the results show that the proposed controller provides improved critical clearing times (CCTs) and an enlarged domain of attraction (DOA) along with improved frequency and voltage regulation.
