Application of Max Flow- Min Cut Theory To Find The Best Placement Of Electronic-based DC-PFCs For Enhancing Static Security In MT-HVDC Meshed Grids

This paper proposes an approach for selecting an optimal placement and control variable setting by finding the worst contingencies for the recently proposed Interline Direct Current Power Flow Controller (IDC-PFC) in MultiTerminal High-Voltage DC (MT-HVDC) Grids based on Max Flow- Min Cut Theory. It is for Optimal PFCs’ placements that purposes to optimize the maximum capacities of the transmission grid. Optimal settings for finding the most critical HVDC lines in a meshed grid and deciding where to place the PFC afterward. The controllable Voltage Source Converters (VSC)s are computed by applying a sequential quadratic programming solver in MatLab to the developed security-based DC optimal power flow problem including several corrective constraints.
