This study offers an approach for determining power flow in an AC system with HVDC link. For AC/DC systems, an unadorned and sound approach for sequential method with modified Gauss Seidel load flow is devised. The conventional technique for solving AC-DC load flow is a simultaneous technique in which the computation burden exists. This leads to the power flow analysis using sequential technique. This technique is based on the implementation of node infusion concept to every bus. The Direct Current system is influenced by the power injected into the buses to which it is linked. The constraints of both the systems are linked by iterations between Alternating Current and Direct Current load flow algorithms. With each iteration of the algorithm of this technique, the connection between the Alternating Current and Direct Current equations of the real and reactive powers at the rectifier buses and also the Alternating Current voltages at the rectifier buses, are used. The devised algorithm to solve 5 bus and 30 bus systems has been run and results are obtained desirably.
