A Full-Newton AC-DC Power Flow Methodology for HVDC Multi-Terminal Systems and Generic DC Network Representation

The use of Direct Current (DC) transmission links in power systems is increasing continuously. Thus, it important to develop new techniques model the inclusion these devices network analysis, order allow studies operation and expansion planning large-scale electric systems. In this context, main objective paper present a methodology for simultaneous AC-DC flow multi-terminal High Voltage (HVDC) system with generic representation DC network. proposed based on full Newton formulation solving problem. Equations representing converters steady-state control strategies are included problem formulation, resulting an expanded Jacobian matrix method. Some results presented HVDC test confirm effectiveness approach.
