Large scale penetration of distributed generation is one of the most important challenges that Smartgrids will need to deal with. Among the possible solutions to increase the amount of distributed generation, there is one that consists in meshing the existing looped (but radially operated) distribution-grid topologies. In order to migrate towards meshed and actively operated topologies, this PhD proposes:- The study a solution that is able to modulate power-flow (active and reactive powers independently) in the ties between distribution grids.- The analyzed solution must also be able to improve power-quality or to avoid propagation of power quality disturbances from one grid to the other.In order to satisfy the double challenge of controlling power-flow and power quality simultaneously, this PhD proposes the use of a Unified Power Line Conditioner (UPLC). Considering the outstanding functionalities of UPLC, the main ambition of the PhD is to explore the potential and the interest of using such an apparatus for interconnecting MV distribution grids.It must nevertheless consider that UPLC is not the only a device capable of combining these functions. A device named Medium Voltage Direct Current (MVDC) can also deal with these multiple objectives. One part of the PhD is thus committed to a comprehensive comparison between both apparatus.
