energy systems with massive integration of renewable energy resources, high-resolution sensors, and advanced measurement devices are more susceptible to cyber-attacks and physical stresses due to their increased complexity and exposure to external systems
and stakeholders. Security and reliability of energy systems are, therefore, crucial for maintaining operational integrity and providing seamless electricity to customers. Modeling the complex energy systems as graphs allows for the incorporation of topology,
interconnection, and inter-relation among the system components into the data analysis for enhancing situational awareness in energy systems. In this presentation, the applications of two powerful graph data analytic tools: graph signal processing (GSP) and
graph neural network (GNN) will be discussed to show their effectiveness in addressing several security and reliability-related problems: 1) detection, localization, and characterization of cyber-attacks, energy theft, and physical stresses in smart grids
and advanced metering infrastructures, 2) recovery, estimation, and prediction of system states, and 3) optimum meter placement in the systems. This presentation covers both accomplished work and future research directions, including extending GSP and GNN
to other networked systems beyond energy systems, e.g., smart cities connecting smart grids, smart transportation systems, and internet-of-things. </span></i></span><span style="color:black"> <o:p></o:p></span></p>
