A security constrained non-convex power dispatch problem with prohibited operation zones and ramp rates is formulated and solved using an iterative solution method based on the modified subgradient algorithm operating on feasible values (F-MSG). Since the cost function, all equality and inequality constraints in the nonlinear optimization model are written in terms of the bus voltage magnitudes, the phase angles, the off-nominal tap settings, and the susceptance values of Static-VAR (SVAR) systems, they can be taken as independent variables.
