VIII. CONCLUSIONS
In this paper, recent advances of the VSC-HVDC technology are presented. The development of high-voltage high-power semiconductors has assisted utilities to exploit the benefits of the four-quadrant static converter interlinking two AC systems through HVDC. The key benefits include independent control of active and reactive power through the PWM control of the converter, fast dynamic response and possibility to connect AC islands with the grid where no synchronous generation

VSC-HVDC technology have delivered systems at voltage levels up to ±150kV and power levels up to 350MW. VSC-HVDC undoubtedly will continue to provide solutions for many challenging issues associated with the modern deregulated power systems where installations and
