Available in PDF, EPUB and Kindle. Book excerpt: This Master Thesis presents the modelling, control and simulation of a hybrid multi-terminal High Voltage Direct Current (HVDC) grid. This network is composed by two point-to-point lines linked by a DC/DC converter. One point-to-point line is based on Line-Commutated Converters (LCC) and the other one is based on Voltage Source Converters (VSC), modeled as Modular Multilevel Converters (MMC). These two technologies are the most used ones in HVDC. The DC/DC converters chosen to analyze the multi-terminal grid are the Front-to-Front MMC and the DC-MMC. In order to achieve the final multi-terminal HVDC grid, the basics of both HVDC technologies are studied. It also includes the modelling, control and simulation of two point-to-point lines. One for LCC technology and the other one for VSC technology. The principles of DC/DC converters are also studied, including the modelling and control of a Front-to-Front MMC converter and a DC-MMC converter. Finally, simulations of the multi-terminal grid are performed with Matlab Simulink in di↵erent scenarios, including four cases for each DC/DC converter. In these di↵erent cases the DC/DC converter is placed regulating the DC voltage or controlling the power flow in the di↵erent point-to-point links.

Book Synopsis Topology and Control of Transformer-less Modular Multilevel DC-DC Converters for HVDC Grid Application by : Fei Zhang
Download or read book Topology and Control of Transformer-less Modular Multilevel DC-DC Converters for HVDC Grid Application written by Fei Zhang and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "A high-voltage direct current (HVDC) system is more efficient at transmitting power over long distances than a high-voltage alternating current (HVAC) system. With the increase in renewable energy integration, HVDC technology is more important for the efficient integration of distributed energy sources (DERs) into grids. The features of a modular multilevel converter (MMC) make it the topology of choice for high-power applications for HVDC systems. To interconnect DC networks with different voltage levels, a DC-DC converter is a crucial component that plays the role of the AC transformer in the AC system. This thesis focuses on the topology of a transformer-less MMC DC-DC converter for HVDC grid applications and its control strategy. The main objective of the thesis is to develop a fully switch-based MMC DC-DC topology without using a transformer or passive filters. The proposed topologies have a hybrid combination of half-bridge submodules (HBSMs) and full-bridge submodules (FBSMs). Moreover, by taking advantage of both HBSMs and FBSMs, the proposed MMC DC-DC converter has the DC fault ride-through capability, which is necessary in DC systems. A family of transformer-less hybrid MMC DC-DC converters with T-type connections is investigated. The optimal selection rules of the submodule (SM) type, based on switch utilization and DC fault blocking capability, are evaluated under different voltage conversion ratios. A modified topology is also investigated to reduce the circulating current that balances the energy between the arms, which has delta-connected FBSMs to simultaneously maintain the unity power operation of the arms with HBSMs and the DC fault ride-through capability. In addition to the topology of an MMC DC-DC converter, a control strategy based on the model predictive control (MPC) of the MMC is presented. A voltage-level based MPC is proposed to address the issue of the large computational burden of conventional MPC used in MMC applications. Instead of directly selecting the switching states, the proposed predictive control has a hierarchical structure that first selects the optimal voltage level by assuming that the capacitor voltage of all SMs is balanced and then balances the capacitor voltages by using a separate control loop. The proposed predictive control is applied to the MMC DC-DC converter to guarantee the converter's fast response during transient operation.The performance of the proposed topology and control strategy is validated using both real-time simulation and a lab-scale, experimental test bench." --

Book Synopsis LCC-HVDC Bipole System with MMC-based DC Tapping Stations by : Manish Persand
Download or read book LCC-HVDC Bipole System with MMC-based DC Tapping Stations written by Manish Persand and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Line Commutated Converter based High Voltage DC (LCC-HVDC) is the dominant technology of HVDC power transmission worldwide. LCC-HVDC has lower cost of implementation and lower power losses, accompanied by higher voltage capabilities and higher power levels, in comparison to Voltage Source Converter based HVDC (VSC-HVDC) technology. However, VSCHVDC has technical superiorities such as independent control of active and reactive powers, elimination of the risk of commutation failures, and drastically reduced size of harmonic filters. Combining the advantages of both the existing LCC-HVDC systems and newer VSC-HVDC technology, hybrid LCCVSC HVDC transmission systems are being developed. As LCC-HVDC lines span very long distances, one particular hybrid system of interest is HVDC line power tapping where a small amount of power is tapped using VSC technology. To date, most systems level research studies on HVDC tapping have focused on using DC-AC VSC stations implemented on monopole systems with simplified controls Moreover, few works explore HVDC tapping using DC-DC converters that can create intermediate medium-voltage DC (MVDC) output buses, which offer increased flexibility for connection to downstream DC-AC VSCs or even for renewable energy integration. This thesis develops a comprehensive tapping study system in RSCAD on an RTDS Novacor simulator, which consists of a ±500 kV 3 GW LCCHVDC bipole system, designed based on the existing 3-Gorges HVDC system, and includes two DC-DC tapping converters using modern Modular Multilevel ii Converter (MMC) technology, one connected at the middle of the HVDC line on each pole. The LCC-HVDC bipole system is modeled on the processor cores of the simulator. The two DC-DC MMCs are implemented using both processor and GT-FPGA based valve models: averaged MMC5 and detailed U5-MMC models for positive and negative pole tapping stations, respectively. The firing controls for the DC-DC MMCs are also modeled using the GTFPGA units. The LCC-HVDC bipole is rated at 500 kV, 1500 MW per pole and each DC-DC MMC is rated at 75 MW, designed with a 500/40 DC step ratio to create a bipolar ±40 kV MVDC output bus. Controls are provided to operate each tap independently. The resulting hybrid LCC-VSC system therefore offers significant flexibility for systems level tapping studies, owing both to its independent pole design but also the realistic LCC-HVDC controls and modes of operation. Simulations are carried out to study independent pole power tapping feasibility as well as bidirectional power flow scenarios involving the tapping stations and their effects on existing LCC systems. Fault Studies were also carried out. Different types of AC and DC line-to-ground faults were triggered on the rectifier and inverter AC networks and HVDC links respectively. In all fault scenarios, the whole hybrid LCC-VSC HVDC system recovers to its pre-fault operating modes once they are cleared.

This book was released on 2019-09-03 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses novel methods for planning and coordinating converters when an existing point-to-point (PtP) HVDC link is expanded into a multi-terminal HVDC (MTDC) system. It demonstrates that expanding an existing PtP HVDC link is the best way to build an MTDC system, and is especially a better option than the build-from-scratch approach in cases where several voltage-sourced converter (VSC) HVDC links are already in operation. The book reports in detail on the approaches used to estimate the new steady-state operation limits of the expanded system and examines the factors influencing them, revealing new operation limits in the process. Further, the book explains how to coordinate the converters to stay within the limits after there has been a disturbance in the system. In closing, it describes the current DC grid control concept, including how to implement it in an MTDC system, and introduces a new DC grid control layer, the primary control interface (IFC).

Book Synopsis A Hybrid LCC-VSC HVDC Transmission System Supplying a Passive Load by : Omar Kotb
Download or read book A Hybrid LCC-VSC HVDC Transmission System Supplying a Passive Load written by Omar Kotb and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High Voltage Direct Current (HVDC) transmission systems continue to be an excellent asset in modern power systems, mainly for their ability to overcome the problems of AC transmission, such as the interconnection of asynchronous grids, stability of long transmission lines, and use of long cables for power transmission. In the past 20 years, Voltage Source Converter (VSC)-HVDC transmission systems were developed and installed in many projects, thereby adding more operational benefits to DC transmission option, such as high controllability, ability to supply weak networks, and reduced converter reactive power demand. Nevertheless, VSC-HVDC transmission suffers from the disadvantages of high losses and cost. In this research, a hybrid HVDC employing a Line Commutated Converter (LCC) as rectifier and a VSC as inverter is used to supply a passive network through a DC cable. The hybrid system is best suited for unidirectional power transmission scenarios, such as power transmission to islands and remote load centers, where the construction of new transmission lines is prohibitively expensive. Control modes for the rectifier and inverter are selected and implemented using Proportional Integral (PI) controllers. Special control schemes are developed for abnormal operating conditions such as starting at light load and recovering from AC network faults. The system performance under steady state and transient conditions is investigated by EMTP-RV simulations. The results show the feasibility of the hybrid system.

Available in PDF, EPUB and Kindle. Book excerpt: The MMC is the dominant voltage-sourced converter technology for HVDC systems including terrestrial power transmission and offshore wind power integration. It is also a state-of-the-art solution for emerging MVDC applications such as bipolar dc distribution and grid integration of renewable energy resources. Significant research has been recently targeting the development of new MMC-based topologies that can reap the benefits of the conventional dc-ac MMC in dc grids and hybrid ac/dc power systems. Notable examples include dc-dc converters, multi-port converters, line power flow controllers and power tapping stations. This thesis introduces the concept of multi-frequency power transfer in MMCs where the magnetics windings are multi-tasked to carry currents with multiple frequency components, namely dc and fundamental frequency. Core dc flux cancellation is imposed by appropriate orientation of the individual windings. This novel power transfer mechanism can eliminate redundant energy conversion through partial-power-processing while offering increased flexibility in converter port power flows. Based on the multi-frequency power transfer concept, new MMC-based topologies are proposed that are well suited for MVDC and HVDC grids and hybrid ac/dc systems. Firstly, a new class of single-stage modular multilevel dc-dc converter, termed the M2DC-CT, is proposed for applications requiring either high or low dc stepping ratios. By placing center-tapped transformer windings in series with the arms in each phase leg, the advantages of minimized ac arm currents and absence of dc voltage stress between windings are simultaneously obtained unlike in prior art. Modeling and analysis gives insight into the M2DC-CT multi-frequency power transfer characteristics and suitable converter controls are developed. Converter operation is validated through simulation and experiment. %The M2DC-CT is further extended into a three-port converter by addition of a grid side transformer winding. Secondly, a dual MMC structure is presented that achieves multi-frequency power transfer by tying together the three mid-points of the converter-side center-tapped transformer windings to form an additional dc port. This creates a bipolar MMC with the ability to balance the dc pole power flows in bipolar dc grids. The employed center-tapped transformer has a Volt-Ampere rating that is the same as a conventional grid interfacing transformer. Dynamic controls formulated in the $\alpha\beta$-frame provide tight regulation of the port power flows while ensuring balanced capacitor voltages. The independent pole balancing capability is confirmed through simulation of detailed MVDC-level and HVDC-level PSCAD models and rigorous experimental testing on a scaled-down laboratory prototype. Thirdly, the aforementioned multi-frequency dual MMC structure is proposed for use as a three-port MMC. It allows simultaneous dc-dc and dc-ac conversions between an ac grid and two dc systems, which is distinctly different from the earlier bipolar dc grid application. The $\alpha\beta$ controls developed earlier are easily extended for the three-port application by assigning appropriate reference signals. Steady-state and dynamic operation of the three-port dual MMC topology is validated by simulation with a HVDC-level PSCAD model and extensive experimental tests. Lastly, a detailed comparative assessment of three-port MMCs for high-power applications is conducted. The proposed three-port dual MMC structure and three-port version of the M2DC-CT are compared against two other existing three-port MMCs, on the basis of efficiency, semiconductor effort, internal energy storage and magnetics. Both MVDC and HVDC case studies are examined including several different power flow cases, with provisions for fault blocking. The results indicate the use of multi-frequency power transfer can enable significant reductions in converter operating losses and cost relative to prior art, depending on the application.

This book was released on 2021-04-22 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photovoltaic (PV) energy generation is an excellent example of large-scale electric power generation through various parallel arrangements of small voltage-generating solar cells or modules. However, PV generation systems require power electronic converters system to satisfy the need for real-time applications or to balance the demand for power from electric. Therefore, a DC-DC power converter is a vital constituent in the intermediate conversion stage of PV power. This book presents a comprehensive review of various non-isolated DC-DC power converters. Non-isolated DC-DC converters for renewable energy system (RES) application presented in this book 1st edition through a detailed original investigation, obtained numerical/experimental results, and guided the scope to design new families of converters: DC-DC multistage power converter topologies, Multistage "X-Y converter family", Nx IMBC (Nx Interleaved Multilevel Boost Converter), Cockcroft Walton (CW) Voltage Multiplier-Based Multistage/Multilevel Power Converter (CW-VM-MPC) converter topologies, and Z-source and quasi Z-source. Above solutions are discussed to show how they can achieve the maximum voltage conversion gain ratio by adapting the passive/active component within the circuits. For assessment, we have recommended novel power converters through their functionality and designs, tested and verified by numerical software. Further, the hardware prototype implementation is carried out through a flexible digital processor. Both numerical and experimental results always shown as expected close agreement with primary theoretical hypotheses. This book offers guidelines and recommendation for future development with the DC-DC converters for RES applications based on cost-effective, and reliable solutions.
