Strategy of Active and Reactive Power Inter-coordination Control Among HVDCs

Applying high‐voltage direct current emergency control to suppress the peak value of ultra‐high‐voltage tie‐line power oscillation

“…Due to the quick response and short-term overload capacity, a supplementary controller can be designed for HVDC to improve the stability performance of AC-DC hybrid power system [7][8][9][10][11][12][13][14][15][16][17][18]. The authors [7][8][9][10][11][12][13] proposed to share the imbalance power by use of HVDCs to improve the transient stability of power system. Besides, many studies show that HVDC supplementary control can effectively improve the damping of interconnected power system and suppress the tie-line power oscillation [14][15][16][17][18].…”
