A HVDC grid based on voltage source converters (VSC) is an attractive solution for the grid-integration of offshore renewable energy, interconnection of AC grids, facilitation of power markets, and energy emergency support. However, the power flow within the DC grids is determined by the line resistance, and cannot be fully controlled by the VSCs only. Thus, Power flow control of DC grids are needed not only to realize the economic operation and power markets, but also to prevent overload of DC… CONTINUE READING
