A Graph Computation based Sequential Power Flow Calculation for LargeScale ACDC Systems
This paper proposes a graph computation based sequential power flow calculation method for Line Commutated Converter (LCC) based largescale AC/DC systems to achieve a high computing performance. Based on the graph theory, the complex AC/DC system is first converted to a graph model and stored in a graph database. Then, the hybrid system is divided into several isolated areas with graph partition algorithm by decoupling AC and DC networks. Thus, the power flow analysis can be executed in parallel for each independent area with the new selected slack buses. Furthermore, for each area, the nodebased parallel computing (NPC) and hierarchical parallel computing (HPC) used in graph computation are employed to speed up fast decoupled power flow (FDPF). Comprehensive case studies on the IEEE 300bus, polished South Carolina 12,000bus system and a China 11,119bus system are performed to demonstrate the accuracy and efficiency of the proposed method
