Cyber-Physical Modeling and Control of Smart Grids - A New Paradigm

The purpose of this paper is to analyze the dynamics of a smart grid in a cyber-physical context. Due to highly complex and interactive nature of smart girds, there is a high risk of instabilities and dynamic variations depending on numerous cyber and physical parameters. An integrated algorithm and simulation involving both cyber and physical variables provide the basis to assure superior performance. In this way, the overall complexity of the system is confined to a high-level hybrid model and thus enables a unified control design to simulate not only the electrical behavior but also the physical interactions with the real world. The basic framework is outlined, demonstrating with an example how interactions between different modes take place, the power processing ability and the system transient response.
