Book Description
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).

Control of a Multi-terminal VSC-HVDC System
Operation and Control of Multi-terminal VSC-HVDC Transmission System
Modeling of Multi-terminal VSC-based HVDC Systems

ISBN:
Category : Electric power systems
Languages : en
Pages : 49
Book Description
"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.
