  • In order to calculate voltage stability margin of hybrid AC/DC system, the primal dual interior point(PDIP)is applied in global optimization. Then a predictor corrector technology is adopted to improve the convergence speed by coordinating the optimality and feasibility. The accuracy and calculation speed of the two algorithms are compared through analyzing the key factor of σ, and the feasibility and the ability of global optimization of both algorithms are compared by taking IEEE 14 bus and 30 bus system as example. Satisfying results are obtained under the same constraints, and also show that the calculation speed has no relation to system scale.
