Review of the Application of Graph Database and Graph Computing in Power System Dispatch and Operation

As the widespread integration of new energy and interconnection of large power grids, the operation modes of power systems are undergoing transformations, which leads to a fast surge in data volumes and higher demands for real-time information processing, and makes system correlations increasingly complex. To meet the characteristics of new power systems, which are large in scale, instantaneous in time, and complex in association, advanced technological methods are needed to achieve efficient data analysis and computation. This paper conducts an in-depth investigation and review of the applications of graph databases and graph computing in power systems. It firstly introduces the basic concepts and development history of graph databases and graph computing, and then systematically reviews the specific application cases of these technologies in power systems with categorized summary. The investigation reveals that graph databases and graph computing have achieved a initial success in application to power systems, which can effectively handling large-scale, complex associated data, significantly improving the efficiency and accuracy of data analysis and computation in power systems. Moreover, the prospects for the application of graph databases and graph computing in power systems are broad. As these technologies continue to develop and improve, they will play an increasingly important role in the intelligent, automated, and efficient operation of power systems.
