This book presents novel contributions in the development of solid-state-transformer (SST) technology both for medium-voltage (MV) and low-voltage (LV) utility grid interfaces, which can potentially augment the grid modernization process in the evolving power system paradigm. For the MV interface, a single-stage AC-DC SST submodule topology has been proposed, and its modulation and soft-switching possibilities are analysed, experimentally validated and adequately benchmarked. A control scheme with power balance capability among submodules is developed for MV grid-connected single-stage AC-DC SST for smooth operation under inevitable parameter drift scenario, and experimental validation shows excellent performance under drastic load change conditions. A novel machine learning-aided multi-objective design optimization framework for grid-connected SST is developed and experimentally validated, which equips a power electronics design engineer with meagre computational resources to find out the most optimal SST design in a convenient time-frame. This book has also contributed towards the development of dual-active-bridge (DAB)-type and non-DAB-type LV grid-interfaced isolated AC-DC converters by providing solutions to specific topology and modulation-related shortcomings in these two types of topologies. A comprehensive comparison of the DAB and non-DAB-type LVAC-LVDC converters reveals the superiority of DAB-type conversion strategy.

Grid converters are the key player in renewable energy integration. The high penetration of renewable energy systems is calling for new more stringent grid requirements. As a consequence, the grid converters should be able to exhibit advanced functions like: dynamic control of active and reactive power, operation within a wide range of voltage and frequency, voltage ride-through capability, reactive current injection during faults, grid services support. This book explains the topologies, modulation and control of grid converters for both photovoltaic and wind power applications. In addition to power electronics, this book focuses on the specific applications in photovoltaic wind power systems where grid condition is an essential factor. With a review of the most recent grid requirements for photovoltaic and wind power systems, the book discusses these other relevant issues: modern grid inverter topologies for photovoltaic and wind turbines islanding detection methods for photovoltaic systems synchronization techniques based on second order generalized integrators (SOGI) advanced synchronization techniques with robust operation under grid unbalance condition grid filter design and active damping techniques power control under grid fault conditions, considering both positive and negative sequences Grid Converters for Photovoltaic and Wind Power Systems is intended as a coursebook for graduated students with a background in electrical engineering and also for professionals in the evolving renewable energy industry. For people from academia interested in adopting the course, a set of slides is available for download from the website. www.wiley.com/go/grid_converters

With the development of renewable energies, such as wind energy and solar energy, the dc power system becomes a promising candidate to manage and transfer the re-newable energy source, which stimulates the study of the dc-dc converters in the past decades. Among various dc-dc converters, the dual-active-bridge (DAB) dc-dc con-verter is regarded as one of the most promising candidates for the dc power conver-sion due to merits like isolated, high-efficiency, bidirectional, and ultrafast dynamic characteristics. Except the DAB dc-dc converter, there are some other isolated dc-dc converters such as full bridge dc-dc converter, three-phase DAB dc-dc converter, etc. They normally have similar dynamic characteristics as the DAB dc-dc converter featuring intermediary inductive ac-link (I2ACL) configuration. However, they are rarely investigated in existing literature, especially for better dynamic control performance. To fill such a gap, the dynamic equivalence between the DAB dc-dc converter and other I2ACL isolated dc-dc converters is revealed with the thorough overview of the existing I2ACL topologies in this work. Further, a unified fast-dynamic direct-current control scheme is proposed for significantly improving the dynamic performance of these I2ACL isolated dc-dc converters. With this predetermined analysis, the dynamic control schemes for the DAB-based dc-dc converter systems can be easily extended to other I2ACL converters with the same configurations. The single DAB dc-dc converter has been extensively investigated, but its modular-ized converter systems such as input-parallel output-parallel (IPOP), input-independent output-parallel (IIOP), in-put-parallel output-series (IPOS), and input-series output-parallel (ISOP) configurations have been seldomly covered in the existing research. Particularly, it is emergent to improve the dynamics, e.g. the input-voltage disturbance, the load-condition change and the power sharing disturbance. In this work, the advanced dynamic controls for these modular DAB dc-dc converter systems are proposed, featuring the flexible power sharing control performances with fast-dynamic responses. Moreover, to realize the reliable operation of these DAB-based systems, the hot swap operations are presented. To ensure the desired power sharing performance, the circuit-parameter estimating methods are proposed for these DAB-based converter systems. This work expands scope of the application of the DAB-based converter system in the partial power processing (PPP). Different from the existing literatures focusing on embedding renewable energy source into the strong ac system, this work proposes a PPP converter system, which can realize the independent control of the renewable energy source and the stabilization of the total dc bus. Combining with DAB module, the DAB-based PPP converter system is proposed. Then, as one of the important functions, the stabilization of the total dc bus should be further improved for this DAB-based converter system. In detail, a high-robustness control strategy is proposed to realize the fast-dynamic control, and the operation when one renewable energy source is out of work is also presented. Notably, the renewable energy should feature the current output and the limited output-voltage regulation such as PV, fuel cell and wind turbine with ac-dc conversion. By using the PV as an example, the effectiveness of the novel system is verified with following results: 1). The maximum power point tracking of the PV panels can be realized by using the existing method. 2). By using the proposed high-robustness control scheme, the total dc-link voltage can maintain at its desired value when the irradiance of PV panels, the voltage of the battery and the load condition are changed, and even when the PV panel is heavily shaded.
