The subject of this thesis is modeling and control of voltage source converter (VSC) fed microgrids. These microgrids are powered by modern distributed generators that require VSCs as part of their grid interface circuitry. This thesis develops two supervisory control schemes that allow VSCs with standard inductor interface and the ubiquitous dq-frame current control to operate in both grid connected and islanded modes. Both of these supervisory control schemes are based on a dynamic model of a VSC fed islanded microgrid, which reveals that the microgrid voltage depends on the real power balance between the VSCs and the load while reactive power balance determines the frequency. Thus, both control schemes set the real and reactive power references of the VSCs to regulate the microgrid voltage and frequency respectively. The Voltage-Power Droop/Frequency-Reactive Power Boost (VPD/FQB) control scheme acts as a supervisory control over the dq-frame current control of a VSC. It allows parallel operating VSCs to jointly regulate a common microgrid voltage and frequency. A VPD/FQB controller droops its voltage reference against the VSC real power output for joint regulation of the microgrid voltage and autonomous real power sharing among the VSCs. Similarly, a frequency-reactive power boost characteristic is employed to achieve joint frequency regulation and autonomous reactive power sharing. A systematic method of coordinating the parameters of parallel operating VPD/FQB controllers is also presented to guarantee damping of inter-controller modes and provide instantaneous load sharing. The second supervisory control scheme, called the Voltage-Power/Frequency-Reactive Power Cross Droop (VP/FQ Cross Droop) control scheme, allows a current controlled VSC to share a common load with synchronous generators as well as other VSCs. A VP/FQ Cross Droop controller droops its frequency reference against the VSC real power output and voltage reference against the reactive power output to share a common real and reactive load respectively. Despite its versatility, the VP/FQ Cross Droop control scheme does not replace the VPD/FQB control scheme in purely VSC fed microgrids due to the former's comparatively poorer inter-controller dynamics.

Microgrids are the most innovative area in the electric power industry today. Future microgrids could exist as energy-balanced cells within existing power distribution grids or stand-alone power networks within small communities. A definitive presentation on all aspects of microgrids, this text examines the operation of microgrids – their control concepts and advanced architectures including multi-microgrids. It takes a logical approach to overview the purpose and the technical aspects of microgrids, discussing the social, economic and environmental benefits to power system operation. The book also presents microgrid design and control issues, including protection and explaining how to implement centralized and decentralized control strategies. Key features: original, state-of-the-art research material written by internationally respected contributors unique case studies demonstrating success stories from real-world pilot sites from Europe, the Americas, Japan and China examines market and regulatory settings for microgrids, and provides evaluation results under standard test conditions a look to the future – technical solutions to maximize the value of distributed energy along with the principles and criteria for developing commercial and regulatory frameworks for microgrids Offering broad yet balanced coverage, this volume is an entry point to this very topical area of power delivery for electric power engineers familiar with medium and low voltage distribution systems, utility operators in microgrids, power systems researchers and academics. It is also a useful reference for system planners and operators, manufacturers and network operators, government regulators, and postgraduate power systems students.

This text is an introduction to the use of control in distributed power generation. It shows the reader how reliable control can be achieved so as to realize the potential of small networks of diverse energy sources, either singly or in coordination, for meeting concerns of energy cost, energy security and environmental protection. The book demonstrates how such microgrids, interconnecting groups of generating units and loads within a local area, can be an effective means of balancing electrical supply and demand. It takes advantage of the ability to connect and disconnect microgrids from the main body of the power grid to give flexibility in response to special events, planned or unplanned. In order to capture the main opportunities for expanding the power grid and to present the plethora of associated open problems in control theory Control and Optimization of Distributed Generation Systems is organized to treat three key themes, namely: system architecture and integration; modelling and analysis; and communications and control. Each chapter makes use of examples and simulations and appropriate problems to help the reader study. Tools helpful to the reader in accessing the mathematical analysis presented within the main body of the book are given in an appendix. Control and Optimization of Distributed Generation Systems will enable readers new to the field of distributed power generation and networked control, whether experienced academic migrating from another field or graduate student beginning a research career, to familiarize themselves with the important points of the control and regulation of microgrids. It will also be useful for practising power engineers wishing to keep abreast of changes in power grids necessitated by the diversification of generating methods.
