A Graph Computing based Power System Transient Analysis Software

With the increasing penetration of inverter based renewable energy and distributed energy storages in nowadays’ power systems, the system status and operation conditions are hard to track with traditional scheduling-based power system transient analysis approach, and more fast and efficient transient analysis methods are needed to address the power system dynamic security problems. This paper proposed a graph computing based power system transient analysis approach to achieve efficient and accurate solution for power system stability analysis. To overcome the data management challenges, a spatiotemporal graph model is constructed for efficient data management in power system transient analysis. Then, a graph computing based transient analysis method is proposed to leverage the parallel computing power to speed up the computational process. Finally, a power system transient analysis software is developed based on the graph computing based transient analysis method to validate the proposed approach.
