Graph Computing based Distributed Fast Decoupled Power Flow Analysis
Power flow analysis plays a fundamental and critical role in the energy
management system (EMS). It is required to well accommodate large and complex
power system. To achieve a high performance and accurate power flow analysis, a
graph computing based distributed power flow analysis approach is proposed in
this paper. Firstly, a power system network is divided into multiple areas.
Slack buses are selected for each area and, at each SCADA sampling period, the
inter-area transmission line power flows are equivalently allocated as extra
load injections to corresponding buses. Then, the system network is converted
into multiple independent areas. In this way, the power flow analysis could be
conducted in parallel for each area and the solved system states could be
guaranteed without compromise of accuracy. Besides, for each area, graph
computing based fast decoupled power flow (FDPF) is employed to quickly analyze
system states. IEEE 118-bus system and MP 10790-bus system are employed to
verify the results accuracy and present the promising computation performance
of the proposed approach.Comment: 5 figures, 3 tables, 2019 IEEE Power and Energy Society General
