Abstract:
This paper investigates the viability of using VSC-HVDC transmission to reinforce the existing HVAC Scottish-English interconnectors in an attempt to increase their power transfer capability without compromising network stability. Two reinforcement schemes are investigated: (1) decoupling the Scottish and English grids by converting the interconnectors into VSC-HVDC links, and (2) reinforcing the interconnectors with parallel VSC-HVDC links. The technical features of each scheme are demonstrated based on a generic model of the GB network implemented in Matlab/Simulink. Key simulation results are presented and discussed in detail.
