Traffic scheduling with sustainable Cyber Physical Systems applying in smart grid

Abstract

CPS, Cyber Physical Systems, one of key techniques in smart grid, makes the electric power system become more intelligent and easier to be controlled, and then the system can provide better quality electric power service for users, great efficiently utilize sustainable, green energy, and decrease carbon emission. Based on distributed agent technologies and traffic engineering, this paper proposes a novel multi-QoS data traffic scheduling algorithm with applying in sustainable cyber physical systems in smart grid. With the algorithm, multiple traffic from second equipments, distribute generation, and dispatching centre can effectively exchange electrical information. Theory analysis proves that the algorithm is convergence and validity. Using the simplified topology from “CERTS Micro-grid System” as simulation case, proposed algorithm's performance is evaluated in different traffic load levels. Bandwidth utilization ratios in light and high load levels are analyzed, it shows that the proposed algorithm makes resource used more balanceable, and congestion can be avoided effectively in high traffic load.
