“…In this context, the HVDC link co-exists with other parallel AC lines and other elements as machines, injectors, etc. This is the case, for example, of the existing links as Caprivi link (Namibia), Kii Channel HVDC Project (Japan), Fenno-Skan (Finland-Sweden), Guizhou-Guangdong (China) [3], Kingsnorth HVDC Link (England) and the HVDC Pacific inter-tie [4] for which many studies as [5,6] were carried out. Note that some of these lines are of considerable length (about 950 km for Caprivi link).…”

When a high voltage direct current (HVDC) link connects two distinct power systems, the latter are usually modelled by two infinite buses. However, in some context of use, the HVDC links are no longer separating two systems but they are embedded into meshed AC systems in parallel with other AC lines and interact with other elements of the power system. This led us to enhance the control objectives by considering stability requirements. In this context, the previous modeling assumption presents serious limitations. Instead, a more efficient control model is used. It is developed such that the concerned dynamics of the system are taken into account during the synthesis. It is shown how the controllers of the HVDC converters can be synthesised using the control model mentioned above such that global grid performances are ensured, in addition to the local objectives like power and DC voltage control. In order to avoid remote measures, an output feedback control which uses only local measures is developed. The new controller is tested in comparison with the standard vector control and a non-linear feedback linearisation control via simulation tests. The tests showed that the controller synthesised using the new control model contributes to a better coordination of the control actions and thus improve grid performances. In particular, the transient stability of the neighbour zone is a priori taken into account at the synthesis level.

The main objective of this paper is three-fold. First, to provide an overview of the current status of the power electronics technology, one of the key actors in the upcoming smart grid paradigm enabling maximum power throughputs and near-instantaneous control of voltages and currents in all links of the power system chain. Second, to provide a bridge between the power systems and the power electronic communities, in terms of their differing appreciation of how these devices perform when connected to the power grid. Third, to discuss on the role that the power electronics technology will play in supporting the aims and objectives of future decarbonized power systems. This paper merges the equipment, control techniques and methods used in flexible alternating current transmission systems (FACTS) and high voltage direct transmission (HVDC) equipment to enable a single, coherent approach to address a specific power system problem, using 'best of breed' solutions bearing in mind technical, economic and environmental issues.

“…The SEPS Laboratory employs a number of power electronic tools including four sets of three-phase thyristor banks (that may be configured as line-frequency, phase-controlled rectifiers and inverters) and two switch-mode inverters with appropriate filters. • Direct Current Transmission-Europe's power grid contains almost 30 high-voltage direct-current transmission links [17]- [19]. The technology becomes increasingly popular with that of power electronics.…”

In this work, the author discusses development of the Smart Electric Power System (SEPS) Laboratory at The College of New Jersey (TCNJ). The fully reconfigurable six-bus, three-phase power system hardware operates with ratings of 208 (at 60 Hz) and 0.2 kW. It is composed of various synchronous generators with associated prime movers, induction motors with associated dynamometers, transformers, transmission lines, contactors, constant-impedance loads, renewable generation-emulator modules, battery storage devices, and appropriate power electronic converters. The SEPS lab significantly expands the ability of faculty and students at TCNJ to study energy problems, providing a sound foundation for the institution's small but growing power engineering program. The National Science Foundation Major Research Instrumentation Program provided external funding for the hardware.
