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).

Download or read book Multi terminal VSC based HVDC Systems for Offshore Wind Energy Systems Integration written by AlMutasim AlSammari and published by . This book was released on 2014 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The installation of wind energy has rapidly increased in the last decade, especially in countries in Europe and East Asia. Offshore wind energy is expected to be one of the major power generation sources in the near future. However, the integrating of offshore wind plants into onshore ac grids remains a challenge in both technical and economic terms. Offshore wind plants can be connected to ac grids using ac or dc transmission systems. HVDC transmission is favored over HVAC transmission as the transmission distance increases. Recently, with the improvement in the field of semiconductor, it became possible to build a VSC-based HVDC system providing many benefits including the ability to independently control active and reactive power transfer. VSC-based Multiterminal HVDC (MTDC) transmission systems allows the interconnection of multiple offshore wind farms with multiple onshore ac grids. The challenges of building MTDC systems has been a hot topic in the past years and it appears this will continue into the future. Different control schemes based on droop characteristics have been presented as a means to regulate the dc voltage and control the power flow in MTDC transmission systems. In this thesis, the control and steady state operation of VSC-based MTDC systems is studied. A generalized control scheme based on droop characteristics is presented. The control methodology is based on the design of the droop constants to control the grid side VSCs for three different operational modes taking into consideration the varying nature of wind power. The three operational modes differ in how the generated wind power is distributed between the ac grids in the MTDC system. The difficulties and challenges of adding tap stations on HVDC lines in MTDC systems is also discussed in the thesis. A new control scheme approach for adding multiple taps on HVDC lines in MTDC systems is presented. A switching VSC models of the MTDC systems discussed throughout the thesis are built in Matlab/Simulink software. The models are simulated for different case scenarios to verify the control and normal operation of the systems.

Download or read book Modeling of Multi terminal VSC based HVDC Systems written by Mohammed Mabrook Alharbi and published by . This book was released on 2014 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Improving the efficiency and operation of power transmission is important due to the continual increase in demand for electric power. In addition, many remote areas throughout the world lack sufficient access to electricity. Unfortunately, utilities cannot satisfy the high demand of power by building new power stations because of economic and environmental reasons. However, utilities can increase generation and transmission line efficiencies by controlling the power flow through their systems. One new attractive technology that enables the control of power flow in the system is Voltage-Source-Converter High Voltage Direct Current (VSC-HVDC) transmission. Multi-terminal-HVDC (M-HVDC) can be built using VSC technology. A model of a three-terminal VSC-HVDC system is presented in this thesis. One of the converters is used to regulate the DC voltage while the others converters control the active power independently and bi-directionally. The vector control strategy and pulse width modulation (PWM) technique are described and implemented in PSCAD/EMTDC. In addition, the region of controllability as a function of power flow has been analyzed. Furthermore, the steady-state and dynamic response characteristics as a function of capacitor size has been investigated"--Abstract, page iii.
