Power DC-to-DC converters are critical to AC and DC microgrids. Among the DC-to-DC power converters, the boost converter has a right half plane zero, which makes it difficult to control. The load voltage must be kept constant, no matter the variations in the input voltage or the change of the load; to achieve this, a negative feedback loop and a control strategy are necessary. This research presents five different digital control strategies to regulate the output of a non-ideal DC-DC boost converter, operating either in continuous conduction mode (CCM) or discontinuous conduction mode (DCM). Four of them are innovative control strategies, implemented by modifying regular K-factor and regular voltage mode control. The fifth is current mode, which is widely used as the industrial standard. A simple algorithm to set up the parameters for each compensator was introduced. In an ideal system, these control strategies performed well, but when time delays were added the performance of the controllers changed significantly, and the stability of the system could be affected. The closed-loop performance of all controllers was evaluated and compared. Simulation results are provided to show the effectiveness of each controller and compare their performance. A laboratory experiment and parametric sweep measurements were made to validate the boost converter small-signal model.

As concerns about climate change, energy prices, and energy security loom, regulatory and research communities have shown growing interest in alternative energy sources and their integration into distributed energy systems. However, many of the candidate microgeneration and associated storage systems cannot be readily interfaced to the 50/60 Hz grid. In Power Electronic Converters for Microgrids, Sharkh and Abu-Sara introduce the basics and practical concerns of analyzing and designing such micro-generation grid interface systems. Readers will become familiar with methods for stably feeding the larger grid, importing from the grid to charge on-site storage, disconnecting from the grid in case of grid failure, as well as connect multiple microgrids while sharing their loads appropriately. Sharkh and Abu-Sara introduce not only the larger context of the technology, but also present potential future applications, along with detailed case studies and tutorials to help the reader effectively engineer microgrid systems.

Microgrids: Advanced Control Methods and Renewable Energy System Integration demonstrates the state-of-art of methods and applications of microgrid control, with eleven concise and comprehensive chapters. The first three chapters provide an overview of the control methods of microgrid systems that is followed by a review of distributed control and management strategies for the next generation microgrids. Next, the book identifies future research directions and discusses the hierarchical power sharing control in DC Microgrids. Chapter 4 investigates the demand side management in microgrid control systems from various perspectives, followed by an outline of the operation and controls of the smart microgrids in Chapter 5. Chapter 6 deals with control of low-voltage microgrids with master/slave architecture. The final chapters explain the load-Frequency Controllers for Distributed Power System Generation Units and the issue of robust control design for VSIs, followed by a communication solution denoted as power talk. Finally, in Chapter 11, real-time implementation of distributed control for an autonomous microgrid system is performed. Addresses issues of contemporary interest to practitioners in the power engineering and management fields Focuses on the role of microgrids within the overall power system structure and attempts to clarify the main findings relating to primary and secondary control and management at the microgrid level Provides results from a quantified assessment of benefits from economic, environmental, operational, and social point-of-views Presents the hierarchical control levels manifested in microgrid operations and evaluates the principles and main functions of centralized and decentralized control
