Fundamental limits on communication latency for distributed control via electromechanical waves

摘要

Cyber enabling infrastructures such as the smart grid transforms many of the it's aspects. A key to many of the promised benefits is the performance of the communication network, mainly in terms of delay and quality. In one area of development, distributed control that rely on received system measurements have shown enhanced system performance against disturbances. We establish a propagation of events framework between the communication system and the physical power system based on electromechanical waves. The proposed framework is used to arrive at fundamental limits of communication latency beyond which distributed control would not be able to properly address disturbances.
