Application of Congestion Notifications in a Cyber-Physical System
Cyber-physical systems augment traditional physical systems with cyber control. These cyber controls are intended to improve the efficiency and availability of the physical system. Smart-grid research focuses on improving the existing power grid with intelligent cyber control. Some smart-grid projects consider a future power grid where energy generation is largely decentralized because of widespread renewable generation and energy storage capabilities. However, if a distributed system is used to control this future power grid, faults in the cyber domain can lead to failures in the physical domain. This work treats communications congestion as a potential fault and makes use of congestion notification techniques to anticipate congestion and reconfigure the distributed system. Dynamic reconfiguration of the system maintains its proper operation in the presence of communications congestion such that proper smart grid operation is maintained. Our approach can be applied to other cyber-physical systems where communication is required for the correct operation of the physical network.
