With the continuous expansion of the scale of the power system and the rapid development of smart grid

distributed energy and demand-side response technology

the role of power grid communication system in real-time scheduling

control and monitoring is becoming increasingly critical. Traditional power communication systems often face problems such as high communication delay

uncontrollable jitter

and difficult to ensure authenticity in complex dynamic environments

which seriously affect the stability and security of the system. Due to its advantages in system modeling

state estimation and dynamic compensation

the control theory method provides a new research path for power communication delay optimization. This paper proposes a network control method that integrates control and communication collaborative optimization

covering latency modeling and impact analysis

event triggering and predictive compensation control

edge computing and time-sensitive network (TSN) scheduling

and authenticity and security mechanism integration. By constructing an integrated verification platform of "simulation-hardware-in-the-loop (HIL)-physical prototype"

the performance is evaluated in the IEEE 39-node system and the actual power grid environment. Experimental results show that the proposed method can significantly reduce communication delay and jitter

improve control performance and system robustness

and provide a systematic solution for the real-time performance and security of smart grid.
