Autonomous microgrids are known to lack appropriate inertia and damping for grid stabilization. Due to this, a virtual synchronous machine (VISMA) has been introduced to provide necessary ancillary services through the control of power converters. In a multi-VISMA (n-VISMA) microgrid, relative rotor angle stability of the power system is dependent on the active power balance after a small perturbation . Using relevant analytical models is an essential issue for microgrid stability analysis. In this PhD dissertation, a comprehensive small-signal stability analysis to study the inherent electromechanical oscillations in the virtual rotors is presented. The subsystems of the microgrid consisting of VISMAs, network, loads and the outer power controller were all modelled in Synchronously-rotating Reference Frame. The small-signal model was tested on IEEE-9 bus system with VISMA replacing the electromechanical synchronous machines on the network. To validate the developed numerical analytics, dynamic responses of the small-signal model are compared with those of the nonlinear system dynamics and the results reveal that the developed linearized small-signal model is sufficient to accurately characterize behaviour of the VISMA microgrid when operated in autonomous mode. Eigenvalues analysis and parameter sensitivities of the critical modes were investigated. Oscillatory participations of the VISMAs and steady state stability limit of the microgrid have also been investigated. However, before starting the stability analysis of the multiconverter based power system with VISMA control, it is necessary to obtain the steady-state operating points (SSOPs) of all dynamic nodes in the network. Modified traditional iterative schemes using the concept of droop bus technique in an islanded microgrid are not feasible for load flow analysis of VISMA microgrid incorporating non-control dynamics. This dissertation thus proposes a closed-form steady-state, fundamental-frequency models for autonomous/islanded VISMA microgrid using the concept of virtual swing bus. In this technique, the virtual internal buses of all VISMAs in the network are governed by the swing equation. The voltage at all buses is variable except the virtual buses in which the pole wheel voltages are prespecified.

Converter-Based Dynamics and Control of Modern Power Systems addresses the ongoing changes and challenges in rotating masses of synchronous generators, which are transforming dynamics of the electrical system. These changes make it more important to consider and understand the role of power electronic systems and their characteristics in shaping the subtleties of the grid and this book fills that knowledge gap. Balancing theory, discussion, diagrams, mathematics, and data, this reference provides the information needed to acquire a thorough overview of resilience issues and frequency definition and estimation in modern power systems. This book offers an overview of classical power system dynamics and identifies ways of establishing future challenges and how they can be considered at a global level to overcome potential problems. The book is designed to prepare future engineers for operating a system that will be driven by electronics and less by electromechanical systems. - Includes theory on the emerging topic of electrical grids based on power electronics - Creates a good bridge between traditional theory and modern theory to support researchers and engineers - Links the two fields of power systems and power electronics in electrical engineering

Synchronous Generators, the first of two volumes in the Electric Generators Handbook, offers a thorough introduction to electrical energy and electricity generation, including the basic principles of electric generators. The book devotes a chapter to the most representative prime mover models for transients used in active control of various generators. Then, individual chapters explore large- and medium-power synchronous generator topologies, steady state, modeling, transients, control, design, and testing. Numerous case studies, worked-out examples, sample results, and illustrations highlight the concepts. Fully revised and updated to reflect the last decade’s worth of progress in the field, this Second Edition adds new sections that: Discuss high-power wind generators with fewer or no permanent magnets (PMs) Cover PM-assisted DC-excited salient pole synchronous generators Present multiphase synchronous machine inductances via the winding function method Consider the control of autonomous synchronous generators Examine additional optimization design issues Illustrate the optimal design of a large wind generator by the Hooke–Jeeves method Detail the magnetic equivalent circuit population-based optimal design of synchronous generators Address online identification of synchronous generator parameters Explain the small-signal injection online technique Explore line switching (on or off) parameter identification for isolated grids Describe synthetic back-to-back load testing with inverter supply The promise of renewable, sustainable energy rests on our ability to design innovative power systems that are able to harness energy from a variety of sources. Synchronous Generators, Second Edition supplies state-of-the-art tools necessary to design, validate, and deploy the right power generation technologies to fulfill tomorrow's complex energy needs.
