This paper illustrates how dedicated droop controls may take advantage of an offshore DC grid topology to implement different power flow policies, without any communication or master control. The issue of DC grid extension is also tackled with a special emphasis on wind spillage: a process to synthesize spatially correlated winds is described and used to assess the value for different extensions and...
The prevalence of cabled infrastructure associated with wind farms, combined with the surge in power-electronic interfaces in wind turbines and reactive power plant, has highlighted the pervasive nature of harmonics on electricity networks. Insufficient consideration is given to the effects of harmonics through the low prioritisation of power quality in the Front-End Engineering and Design (FEED)...
This paper focuses on the control schemes required on offshore VSC-HVDC networks to transmit the power to the onshore grid and provide fast frequency response for the AC grid. The simulation results show the benefits of such control scheme to restore the frequency in the grid after a loss of generation. The results further investigated the consequence of frequency disturbance in the islanded offshore...
