Abstract AC-DC power flow calculation is the basis for studying HVDC system. Since the traditional iterative methods need alternative iteration for many times and have convergence problem, this paper analyses the causes of many iterations firstly, and then proposes a new AC-DC power flow calculation method that is suitable for AC-DC power grid with voltage source converter (VSC). The algorithm re-divides AC-DC power system, incorporates interface equation into AC power system, and augments AC Jacobi matrix with variable of DC system. This algorithm can realize AC-DC decoupled power flow calculation, and has the convergence property of unified method while inheriting convenient control mode strategy of traditional alternating iterative method. The examples of modified IEEE 30-node system and IEEE 57-node system show the correctness and effectiveness of the method.

Key words： Power flow calculation augmented Jacobian matrix VSC-HVDC AC-DC power grid alternating iterative method decoupling
