A method and an apparatus for Security Constrained Economic Dispatch SCED calculating for a hybrid power system (10) that includes one or more AC grids (12) and one or more multi-terminal High Voltage DC HVDC grids (14). Included are optimizing a non-linear objective function, subject to a set of constraints that include AC and DC grid constraints, for determining the SCED solution using successive linear approximation. The linear programming model used in the linear approximations is advantageously augmented with a DC grid (12) portion in a manner that accounts for the effects of the DC grid (14) on the AC grid (12), and which conforms the resultant SCED solution to all applicable AC and DC grid constraints, including AC grid line flow constraints, AC grid power balance constraints, DC grid line flow constraints, and DC grid power balance constraints. |
