Simulation of HVDC System Connected to AC Buses In Close Proximity

This paper highlights the simulation of multiple-infeed converter (MIC) system with the help of "Matlab/Simulink" as AC/DC systems become further integrated as multiple in feed converter (MIC) system can be expected to become more common. In this a) different categories of MIC systems are defined , b) the impact of AC system strength & c) dynamic interaction between HVDC system connected to AC buses in close proximity and performance of such systems are highlighted. Simulation results with the help of "Matlab/ Simulink" are presented which provides some insight into dynamic behaviour of 1 category of such systems.
