This paper proposes a graph computation based sequential power flowcalculation method for Line Commutated Converter (LCC) based large-scale AC/DCsystems to achieve a high computing performance. Based on the graph theory, thecomplex AC/DC system is first converted to a graph model and stored in a graphdatabase. Then, the hybrid system is divided into several isolated areas withgraph partition algorithm by decoupling AC and DC networks. Thus, the powerflow analysis can be executed in parallel for each independent area with thenew selected slack buses. Furthermore, for each area, the node-based parallelcomputing (NPC) and hierarchical parallel computing (HPC) used in graphcomputation are employed to speed up fast decoupled power flow (FDPF).Comprehensive case studies on the IEEE 300-bus, polished South Carolina12,000-bus system and a China 11,119-bus system are performed to demonstratethe accuracy and efficiency of the proposed method
