“…Based on this principle, many different approaches have been proposed [15,17,14,18,19], all aiming at avoiding the use of additional equipment, and therefore lowering the cost and power losses. It is noted, though, that there are numerous challenges yet to be considered including properly handling mechanical stresses, overcoming the need for communication signals to achieve faster responses, and addressing the frequency/angular stability issues of the AC system.…”

Multi-terminal Voltage-Sourced Converter (VSC) High Voltage Direct Current (HVDC) transmission is expected to play a key role in future power transmission grids. Compared with AC transmission, DC transmission is more vulnerable to faults due to the lower DC side impedances and sensitive power electronics used in the converters. DC protection issues must be solved before any multi-terminal VSC-HVDC grid can be established. In terms of DC protection, apart from using a DC circuit breaker to interrupt and isolate a DC fault, a Fault Current Limiter (FCL) may be employed to limit the fault current. FCLs could potentially form an important part of any future DC protection system. This paper investigates such a FCL. The main contribution of this paper is that, the resistive type superconducting FCL (SCFCL) is modelled in detail to perform DC protection with the ABB hybrid circuit breaker, in a high fidelity four-terminal VSC-HVDC system model. The simulation results show that the SCFCL has great potential to be employed for DC protection.

This work presents the analysis of a radial plus VSC-HVDC scheme in terms of its impact on AC and DC system dynamics. This study uses the classical two-area system with modified demand as an onshore AC grid. Full converter wind power plants (WPPs) are connected to the main grid through two point-to-point VSC-HVDC links, which are connected offshore through an AC cable to form a 'radial plus' strategy for VSC-HVDC connection. A variety of different control schemes for the radial plus VSC-HVDC are described and analysed to find out the impact of these controllers on the dynamic behaviour of the system. Simulation results are presented to illustrate the impact of different control combinations on system dynamic performance under various grid disturbances.
