An investigation of power flow control methods in multi terminal high voltage DC grids

Abstract

Some significant problems prevent the formation of multi terminal high voltage DC grids until now. Absence of power flow control is considered one of the main challenges that have to be solved in the near future to allow building of an efficient DC grid. This paper investigates different power flow control methods. Simulation of series insertion of AC/DC converters is carried out using MATLAB/SIMULINK software package and results are discussed.
