Abstract
This paper proposes the use of a transformer-less
DC-DC Modular Multilevel Converter (MMC) topology, based
on cascaded H-bridge converters, for power flow control in High
Voltage Direct Current (HVDC) grids used to connect off-shore
wind power plants to on-shore grids. An energy based approach
is used to regulate the DC voltage of H-bridge modules. Results
for the operation of the DC-DC MMC supplying energy to a DC
network and controlling the power flow in a HVDC system are
presented.The support of Fondecyt grant 1151325,
