Graph Database and Graph Computing for Cyber-Physical Power Systems

Cyber-physical Power System (CPPS) presents a typical coupling graph structure composed of nodes and lines/links on both physical side and cyber side. With the rapid development of smart grids and coupling between cyber networks and physical networks, the CPPS network becomes larger and more complex. Since the natural graphic features of CPPS networks and its analysis methods are mostly inseparable from the graph theory, the application of graph computing systems and graph database will greatly help the analysis of CPPS problems. First, the representative graph computing systems are briefly introduced in this paper. And then, considering two-layer coupling structure of CPPS, the architecture consisting of the graph database and the graph computing system for CPPS is proposed.
