The ATC model of AC-DC combined system based on voltage stability constrains is summed up as optimization problem
which is solved by original-dual interior point algorithm.First the Jacobi and Hessian matrix in the Cartesian coordinate system are derived from the converter conversion equations
coupling relation between AC system and DC system
then sub-solving method is proposed to solve ATC in varies control modes of AC-DC combined system within voltage stability constrains.The numerical example provides that the algorithm can consider DC variable constraint and operation mode adjustment easily
not sensitive to the initial value and have fewer numbers of convergence iteration.
