HVDC-Light has the advantages of flexible operating ways and reliability, especially in the transmission problem of offshore wind power. But it needs many PI controllers in the two converters (wind farm side, grid side). So there are many parameters need to be set which is difficult. This paper adopted the control mode that the outside loop controlled the voltage and the inside loop controlled ...

With the increase in use of power electronics in transmission and distribution applications there is a growing demand for cost effective and highly efficient converters. Most of the utility applications have power electronics integrated in the system to improve the efficiency and functionality of the existing system. The development of semiconductor devices is vital for the growth of power elec...

This paper describes the design of controllers for a Voltage Source Converter High Voltage Direct Current (VSC HVDC) power terminal, a MIMO plant that must operate over a wide range and that experiences disturbances due to Pulse Width Modulation (PWM) switching. The controllers are designed using two approaches: the Glover–McFarlane loop shaping procedure (LSDP), and a novel implementation of a...

TERNA, the Italian TSO, is planning new HVDC interconnections with neighboring countries including underground links based on VSC technology; short circuit transient studies of such links require accurate cable line modeling in a frequency range from dc to 10 kHz at least. The finite section approach was used to this purpose. Short-circuit transient simulation results evidenced significant temp...
