Book excerpt: A solid-state transformer (SST) is a power electronics converter that converts high voltage alternating current to low voltage alternating current and it aims to replace conventional 60 Hz power transformers. The SST has been regarded as one of the most emerging technologies in power distribution systems. Transferring energy through a high-frequency transformer with power electronics brings SST advantages of low volume, low weight, fault isolation, and potential additional functions, such as voltage regulation, harmonic filtering, reactive power compensation, etc. However, the involvement of a large number of power devices makes the control of an SST a challenge. In addition, the high voltage and high-power hardware design of the SST are not easy. To resolve these issues, this research seeks to develop a modular solid-state transformer (MSST). Specifically, the overall SST system is built by multiple identical isolated AC/AC converter modules connected in an input-seriesoutput-parallel configuration. Also, a distributed control algorithm has been developed for MSST to further increase modularity. The proposed solution of SST significantly reduced the overall system complexity and cost. Compared to previous research on SST, MSST improves both conversion efficiency and power density. The modular architecture allows more flexibility on converter module design optimization. Therefore, optimization of the isolated DC/DC converter stage is studied in this research. The hardware implementation and a distributed control algorithm will be illustrated in detail. Simulation and experiment results will be shown to demonstrate the feasibility and performance of MSST

Available in PDF, EPUB and Kindle. Book excerpt: "A Solid State Transformer (SST) performs the tasks of a conventional transformer by means of power electronic converters and high-frequency transformers. In addition to voltage level transformation, some SST topologies are able to provide ancillary services to the AC grid.In a three-stage SST, the first-stage is an AC/DC converter. In most designs, this stage employs a multilevel converter topology rather than a two-level converter. The reason for this is that a multilevel converter provides such advantages as capability to interface with a medium voltage AC grid. Among all multilevel converter topologies, a new generation of multilevel converters called Modular Multilevel Converter (MMC) has been considered to be a promising topology for medium/high voltage converters in back to back and High-Voltage DC (HVDC) applications.This thesis first studies the design, modulation, and control of an MMC. In this context, a modulation and control strategy is proposed which decreases the level of harmonics in the output voltage and current of the converter. Further, the proposed strategy pushes the harmonics towards higher frequencies and, hence, allows the converter to be switched at lower frequencies. Next, this thesis proposes a number of three-stage SST configurations employing an MMC in their first stage. An advantage of the proposed SST configurations is that they are readily scalable to higher voltage levels and power ratings; this enables the application of an SST in higher levels of electrical grids. Further, the proposed SSTs feature a high-voltage DC terminal in addition to the commonly provided terminals to enable connection of the SST to a DC distribution grid." --

D. in electrical and computer engineering) and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As an eventual replacement of the century-old line frequency transformer (LFT), the Solid-State Transformer (SST) has been investigated intensively in the past decade due to its ability to offer higher power density and many smart functionalities, such as output voltage regulation, grid reactive power support and power flow control in the distribution grid. As more and more distributed energy resources (DERs) are connected to the grid to achieve the high penetration of renewable energies, the SST serves as an Energy Router, the intelligent interface between the DERs and the distribution grid. To make the deployment of the SST simple and efficient, SSTs should also provide power and communication plug-and-play (PnP) feature. The power PnP feature enables instant power exchange between the medium voltage distribution grid and the DERs and loads, and the communication PnP enables the instant management and many SSTs as a collective Energy Routers. So far, the investigation on the SST with the PnP feature is limited. This thesis’s main contribution is to investigate the capability of a proposed PnP SST, which can achieve immediate power flow once the connection between SST and the medium voltage grid is established. The proposed PnP SST has an input-series-output-parallel (ISOP) modular configuration using a number of SST cells. This greatly improves the scalability and reliability of the PnP SST for medium voltage application. To better adopt the PnP feature, a distributed controller solution is proposed to control the SST cell. To further improve the power density and control robustness, a single stage direct AC/AC power conversion topology is used for the PnP SST. The AC/AC converter employs the soft switching LLC resonant converter to improve the power efficiency. To enable the PnP start-up of the SST, a distributed Flyback auxiliary power supply is proposed to facilitate automatic control power generation. For the modular PnP SST, the input voltage balance is a major concern and is investigated in this thesis. A major contribution from this research is that the LLC based modular PnP SST solution can achieve input voltage balance even with an open loop control, eliminating complex centralized controller needed in traditional SST. The voltage balance performance is capable of tolerating component parameter variations within a reasonably large range. This paves the way for the PnP to achieve very high input voltage needed for medium voltage grid connection. The modular PnP SST also features very high input impedance hence very low in-rush current. Direct PnP to the medium voltage grid can be applied to simplify the installation and the need for a large in-rush current limiter is eliminated. The salient smart functions of the proposed PnP SST is also investigated. The investigation indicates that the proposed PnP SST has the capability of achieving fast dynamic voltage regulation, bi-directional power flow, and reactive power processing. A SiC based PnP SST prototype was developed as part of this thesis. Experiments verified that the SST cell achieves 97.88% peak efficiency. Each cell has a 11 kW power capability and a 550Vrms input voltage. The natural input voltage balance is verified by the PnP SST prototype with two SST cells

Available in PDF, EPUB and Kindle. Book excerpt: What Is Solid State Transformer In actuality, an AC-to-AC converter, also known as a solid-state transformer (SST), power electronic transformer (PET), or electronic power transformer, is a type of electric power converter that replaces a conventional transformer in AC electric power distribution. This type of electric power converter is known as an AC-to-AC converter. Because it works at a higher frequency, this kind of transformer is more complicated than a traditional transformer that uses the utility frequency, but it also has the potential to be more space-efficient and smaller than a traditional transformer. The two primary varieties are referred to as "real" AC-to-AC converters and AC-to-DC-to-DC-to-AC converters, respectively. The AC-to-AC converter or DC-to-DC converter that is often found inside of a solid-state transformer is really a transformer. This transformer is what provides the electrical isolation and carries the entire power. This transformer is more compact because the DC-DC inverting stages that occur between the transformer coils are on the smaller side. As a result, the transformer coils that are needed to step up or step down voltages are also on the smaller side. Active regulation of voltage and current may be performed via a solid-state transformer. There are several that are able to convert electricity from single-phase to three-phase and vice versa. The amount of conversions that need to take place may be decreased by having variations that can either input or output DC power. This results in increased end-to-end efficiency. A Modular Solid-state transformer is similar to a Multi-level converter in that it is made up of numerous high-frequency transformers and has the same function. Because it is an intricate electrical circuit, it has to be constructed such that it can survive surges of various kinds, such as lightning. The solid-state transformer is a relatively new kind of transformer.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modern electrical power grid increasingly features semiconductor-based power electronics converters in place of traditional transformers. Known as solid-state transformers (SST), these converters are distinguished for their controllability, their efficiency, and their reduced size and weight. Of the existing converter topologies, the modular multilevel converter (MMC) is popular for implementation as a solid-state transformer, including in direct current (DC) grid interfaces. In the existing engineering literature, the MMC is often studied operating under a low-frequency sinusoidal modulation, and is often implemented with large passive components. This tends to make the converter more stable, and relaxes the requirements placed on the control system. By changing the MMC so that it instead operates with a medium-frequency square waveform in a DC SST, the passive components can be significantly reduced, as well as the semiconductor device ratings. However, a greater emphasis and burden is then placed on the control system's speed and accuracy. This is problematic because an MMC with small passive components experiences tight coupling among its state variables, which significantly complicates efforts to design a traditional control system for it. This dissertation proposes and investigates methods for modeling and controlling an MMC that uses small passive components. Two major strategies are investigated: two approaches based on the traditional proportional-integral (PI) control, and one approach based on the increasingly popular model predictive control (MPC). By taking advantage of the square-wave operation, it is possible to design simplified model-based PI controllers that achieve power flow control. A more complete model that fully accounts for the MMC's internal dynamics is also proposed and studied in this dissertation. Although it is difficult to apply the full benefits of this model to PI controller design, an MPC-type controller can easily make full use of it and achieve good control of the MMC's power flow and internal dynamics. Unlike most other MPC controllers in the engineering literature, the MPC controller proposed in this dissertation has a very low computational burden and does not require iterative solutions. Simulation and experimental results are provided to validate the proposed models and the developed control systems.

This book was released on 2015 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Due to recent advancements in semiconductor technology, power electronic converters for high voltage, high power, and high frequency applications will soon be commercially available. Conventional single phase distribution transformers are replaced by solid state transformers (SST) in a distribution test system to investigate their interactive dynamics. Under certain circumstances, instabilities due to harmonic resonance are observed. A design criterion for solid state transformer during no load conditions has been proposed in order to avoid instability using an impedance-based analysis. Stability assessment is also extended to include the impact of distribution system voltages and system wide impedance analysis. It is shown that if the SST filters throughout the system are designed with regards to the proposed stability criterion, then system stability is guaranteed regardless of configuration. This leads to two resulting applications: (1) the order in which the SSTs are connected to the system will not generate instability if the criterion is satisfied, and (2) a system configuration change due to a fault will not produce instability. In distribution power systems, feeder voltages can be very sensitive to changes in load and/or distributed generation. A solid-state-transformer-based local voltage control strategy is introduced to reduce variability distribution system bus voltages. An on-line dynamic volt-var control (VVC) algorithm is proposed to regulate bus voltages by injecting or absorbing reactive power through a solid state transformer. The main goal of the algorithm is to enforce strict voltage constraints on the system voltages. The proposed control algorithm is validated in both a radial and meshed distribution system."--Abstract, page iv.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional radial AC distribution systems cannot effectively accommodate the rapidly increasing renewable energy sources (RESs) and new loads such as fast charging stations of electric vehicles. To address the pressing challenges, active distribution grids and DC systems have attracted significant interests with their many potential benefits. Considering that AC and DC systems will coexist in future distribution grids wherever suitable, hybrid AC/DC distribution is regarded as a promising and practical solution for future distribution systems. The focus of this work, multiport interlink modular multilevel converter-based solid-state transformers (iMMC-SSTs), is expected to play a key enabling role in hybrid distribution systems to integrate different grid entities, including both AC and DC networks at both medium and low voltage levels. The iMMC-SST features capabilities such as bidirectional power transfer, fault isolation and restoration, system reconfiguration, and voltage regulation. However, power electronics-based SSTs are more vulnerable under abnormal conditions, which hinders their adoption in practical systems. The high number of circuit elements are potential fault sources in the iMMC-SST. The possible faults of the SST and the connected feeders can destroy balance of the system and even result in second faults. A comprehensive protection scheme for the iMMC-SST is indispensable to ensure the device's safety and improve the system's reliability and robustness. Based on the fault location, abnormal conditions are in general divided into external and internal types. In this work, grounding scheme for the SST is designed and investigated to address typical external fault conditions such as the single line-to-ground (SLG) short-circuit fault and single pole-to-ground (SPG) short-circuit fault. For internal abnormal conditions, power switch faults are of major concerns of the iMMC-SST since a switch failure will lead to arm voltage imbalance, circulating current increase, and second faults. The submodule (SM) switch open-circuit (OC) fault analysis is presented considering different operation modes of the iMMC-SST in Chapter 4. Unlike traditional MMC applications, the iMMC-SST has different fault characteristics, and the previous fault diagnosis and fault-tolerant schemes developed for other applications are not applicable here. Based on detailed analysis of the fault behaviors, a fault-tolerant scheme based on the global redundant module and unbalanced control is proposed in Chapter 5. Similarly, the dual active bridge (DAB) switch OC fault is studied in detail, and a DC current injection fault-tolerant method is proposed to address the overcurrent and transformer saturation issues in Chapter 6. The proposed solutions and their analysis are verified with MATLAB simulations and experiments with scaled-down laboratory prototypes.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The solid state transformer (SST) is seen as a proper replacement of the conventional iron-and-copper transformer in the future smart grid . The SST offers several benefits (e.g. enhanced power quality performance or reactive power control at both primary and secondary sides) that can be of paramount importance for the development of the smart grid . This research focuses on the development and implementation of an advanced model of a three stage bidirectional SST in Matlab/Simulink. The goal is to obtain an realistic SST model (i.e. as close to the real SST as possible) that could duplicate the performance of a real MV/LV SST. This considered design consists of three main stages: medium voltage (MV) stage, isolation stage, and low voltage (LV) stage. When the power flows from the MV side to the LV side, the input power-frequency ac voltage is converted into a MV dc voltage by the three-phase ac/dc converter, which in such case works as rectifier. The isolation stage, which includes a high-frequency transformer (HFT) and the two corresponding MV- and LV-side converters, first converts the MV-side dc voltage into a high-frequency square-wave voltage applied to the primary of the HFT; the secondary side square-wave signal is then converted to a LV dc waveform by the LV-side converter, which also works as rectifier. Finally, the output LV-side three-phase dc/ac converter, which works as inverter, provides the output power-frequency ac waveform from the LV-side dc link. Si-based semiconductor technologies can be used for MV applications using a multilelvel configuration. Recently, modular multilevel converter (03C) topologies have attracted attention for high or medium voltage applications. These converters can provide an effective topology for the MV side of the SST; their main advantages are modularity and scalability: the desired voltage level can be easily achieved by a series connection of 03C sub-modules (SMs). In addition,a 03C topology can provide high power quality and efficiency with reduced size of passive filters. These features made the 03C option an attractive topology for the MV stage of the SST. This thesis proposes a three-stage SST configuration based on 03C technology for MV converters. * The input stage of the SST is connected to the distribution system via RL filters and its three-phase configuration uses a 03C technology. A half-bridge configuration is proposed for each SM. * The isolation stage consists of three parts: a MV single-phase 03C, the high-frequency transformer (HFT), and a single-phase LV PWM converter. * The LV side of the SST uses a three-phase four-leg PWM converter, with an RL impedance for filtering currents and a capacitor bank for filtering voltages. The converters and their controller have been implemented adn tested considering models without and with semiconductor losses, while the SST model has been tested as a stand-alone device and a compnent of a distribution system. The model has been tested under severe dynamic and unbalanced conditions. The simulation results support the choices made for any SST stage and proves that the proposed design could be a feasible choice for the future SST.

Book excerpt: The Modular Multilevel Converter (MMC) or the Bridge of Bridge Converter (BoBC) are emerging to be a technically viable approach for realizing a wide range of power conversion applications, thanks to its use of identical power circuit modules as building blocks, and scalability for freely extending to multiple series levels or parallel branches. In spite of this, the application range of MMC have been highly restricted by two major disadvantages. (1) While commercial applications of MMC at utility scale has expanded in recent years, where robustness is as important as power rating, they have no share in the market for board and chip level power conversion applications, where power density and overall price are highly sought after, due to size constraints and profit margins. (2) Control strategy and data communication interface between MMC system controller and MMC modules become increasingly complicated as more modules are added into the system. This disadvantage overpowers the advantages brought by the MMC topology due to increased system control complexity. The proposed MMC system in this research aims at overcome the disadvantages of conventional MMC system, by developing reconfigurable system architecture based on identical modules at chip-level or board-level, including the control system. In light of this, following solutions are presented in this research following a progressive manner: (1) Design similarities in modularity and scalability between MMC and very large scale integration (VLSI) are identified as an advantageous feature that enables mass manufacture of MMC modules. Using modern fabrication techniques of integrated circuit (IC), partially integrated prototype modules have been developed and fabricated, and MMC prototypes for different power conversion applications have are demonstrated based on these modules. (2) A distributed control strategy with minimal requirements for global control and communications that is specially tailored for the MMC is proposed and demonstrated. The conventional pulse width modulation (PWM) with stringent time synchronization requirements is replaced by the delta-sigma modulation (DSM) which requires no switching signal synchronization, with a primary goal to reduce the required data transfer rate. Digital controller is embedded into each module and generates control commands locally, with a goal to reduce the total amount of tasks been processed by the system controller, and reduced the state variables required for feedback. In order to demonstrate these solutions, various designs, simulations, fabrications, prototyping and testing have been conducted at different scales ranging from chip-level to system level. The experimental results establish the viability of the proposed approach, and analysis of the experimental data has confirmed the technical feasibility of concepts. Directions for further investigations to translate this work to practice are identified in the thesis.
