Implementation of a Testbed with SDN-enabled Communication Networks to Experiment on Physical Function Virtualization that Disrupts Reconnaissance of Cyber-Physical Infrastructures
… deployed in the real world. Large ICSs, such as smart power grids, consist of the supervisory control and data acquisition (SCADA) systems and the programmable logic controllers (PLCs). PLCs and SCADA exchange control signals and measurement data through a communication network. As an ICS scales, …

Distributed online algorithms for energy management in smart grids
The 21st-century electric power grid is transitioning from a centralized structure designed for bulk-power transfer to a distributed paradigm that integrates the variable renewable energy (VRE) resources spatially distributed across the grid. This work proposes algorithmic solutions for distributed …
