摘要：
The hybrid multi-terminal HVDC (MTDC) with a combination of LCC (Line Commutated Converter) and VSC (Voltage Source Converter) eliminates all the disadvantages of these two HVDC technologies. Complex control schemes are required to operate this system under different operating conditions. This paper presents control schemes for a hybrid MTDC to guarantee a safe operation under different loading conditions and when faults occur. The developed control scheme is implemented on the Simplified South East Australian 14 generator system in DIgSILENT PowerFactory environment. The simulation results demonstrate the effectiveness of the proposed control scheme in reducing the grid active power losses and significantly improving the system transient stability.
