The recent progress of high-voltage high-power fully controlled semiconductor technology laid the foundation of VSC technology, which continues to advance the developments of HVDC technology and FACTS., However, the high penetration of VSC based systems may introduce certain risks to existing power systems in two primary aspects: dynamic stability and protection. This thesis investigates the impacts of VSC HVDC and VSC FACTS on system dynamic stability and protection. An integrated small-signal stability model for the study of interactions between CFC and VSC is established. Modal analysis results are verified by simulation results from RTDS under both small and large AC/DC disturbances. The impacts of control parameters of CFC on the integrated AC/DC system and the interactions between VSC and CFC are investigated using both modal analysis and time-domain simulations. The mathematical representation of the apparent impedance measurements of distance relay is derived considering the infeed current from VSC HVDC and VSC FACTS at different locations. A RTDS-based HIL testing platform is established. The impacts of VSC HVDC and VSC FACTS on feeder distance protection are investigated, based on different types of internal/external fault test simulation occurred at various locations.

Electric power systems are headed for a true changing of the guard, due to the urgent need for achieving sustainable energy delivery. Fortunately, the development of new technologies is driving the transition of power systems toward a carbon-free paradigm while maintaining the current standards of quality, efficiency, and resilience. The introduction of HVDC and FACTS in the 20th century, taking advantage of dramatic improvements in power electronics and control, gave rise to unprecedented levels of flexibility and speed of response in comparison with traditional electromechanical devices. This flexibility is nowadays required more than ever in order to solve a puzzle with pieces that do not always fit perfectly. This Special Issue aims to address the role that FACTS and HVDC systems can play in helping electric power systems face the challenges of the near future.

This thesis investigates the use of flexible AC transmission systems (FACTS) and voltage source converter (VSC) high-voltage direct current (HVDC) transmission systems for improving the power transfer capability of the Libyan internal tie-line between east and west, for a secure, reliable and efficient operation of this power corridor. Mathematical-based analysis supported by numerical-based analysis, which employs NEPLAN power system analysis tool, are carried out to investigate the steady state and dynamic behaviour of the power system.Different FACTS technologies, including variable impedance based and converter-based shunt and series FACTS devices, are studied during steady-state and transient operating conditions to evaluate the capabilities, control systems and weaknesses in these technologies. The investigations focus on the common types of shunt and series FACTS including: the static VAr compensator, static synchronous compensator, and thyristor controlled series compensator. A challenge in this thesis is to find an efficient method to allocate and size FACTS devices, to ensure maximum utilization of the tie-line considering technical constraints including:; voltage rise at a point of voltage collapse, equipment terminal voltage and subsynchronous resonance risk.For the VSC-HVDC system, a mathematical model that calculates power flow throughout the HVDC link and at both AC sides is confirmed as an efficient steady-state model facilitating estimation of reactive power requirements at the converter terminal and at the point of common coupling. This model can be used to estimate the optimal converter rating based on the system strengthens at both sides. Further modelling and analysis investigates the operation of a hybrid AC/DC system. Multi-tasking control systems for voltage source converter HVDC systems are used to facilitate operation of the hybrid AC/DC system during normal and emergency operating conditions. The controllers include: frequency control in the case of an unsynchronized connection and power management control necessary to balance the power flow during an emergency, in additional to the primary control of the AC and DC voltages, and active and reactive powers.Well-known and referenced two areas Kundur test system with a weak tie-line, which suffers from a limited power transfer capability between the operating areas, is used throughout the analysis. the tie-line between two regions in the Kundur test system is investigated when incorporating different FACTS technologies and a VSC-HVDC system. Based on the introduced approaches and models the benefits and challenges of these technologies in the Libyan internal tie-line are explored. The research shows that the power transfer capability of the tie-line can be improved by shunt and to a lesser extent, by series compensation. Comparison between FACTS devices and VSC-HVDC indicates, apart from the cost, VSC-HVDC transmission may be the better option for Libyan internal tie-line improvement, especially in the near future, when secure and reliable interconnected power system is required.

Flexible AC Transmission Systems (FACTS): Newton Power-Flow Modeling of Voltage-Sourced Converter-Based Controllers introduces different voltage-sourced converter (VSC)-based FACTS controllers and VSC-based high-voltage direct current (VSC-HVDC) systems and their working principles, explaining how FACTS controllers exchange real and reactive power with systems. Subsequently, the book: Describes the Newton–Raphson method and its application for solving the power-flow problem Presents the Newton power-flow modeling of the static synchronous series compensator (SSSC), unified power-flow controller (UPFC), interline power-flow controller (IPFC), generalized unified power-flow controller (GUPFC), and static synchronous compensator (STATCOM), accommodating the practical device constraint limits (because of the unique modeling strategy, the existing Newton power-flow codes can be reused) Develops a unified Newton power-flow model of AC systems incorporating multiterminal VSC-HVDC systems with pulse-width modulation (PWM) control schemes, directly yielding the VSC modulation indices from the power-flow solution Provides numerous case studies for validation of Newton power-flow models, elaborating on the occurrences and checking of unrealistic power-flow solutions in isolated cases Includes detailed derivations of all the difficult formulae as well as solved problems on typical VSC-based FACTS controllers Flexible AC Transmission Systems (FACTS): Newton Power-Flow Modeling of Voltage-Sourced Converter-Based Controllers assumes at least an undergraduate-level understanding of engineering mathematics, network analysis, electrical machines, electrical power systems, and power electronics. Thus, the book provides a valuable reference for practitioners as well as senior-undergraduate and graduate students in electrical engineering and electrical power systems.
