Data transmission of cyber physical power system

Abstract

Aiming at monitoring the behaviour of power system to make it work correctly and better, cyber physical power system (CPPS) was introduced. However, due to the high integration of cyber system, the complexity of power system is greatly enhanced, which puts forward higher requirements for the reliable and safe operation of CPPS. Moreover, when the cyber system is under attack, abnormal information flow may lead to abnormal energy flow. Therefore, this paper proposes a data transmission mechanism to analyse the information flow among CPPS. A data transmission optimization model based on the transmission matrix is constructed. The data transmission from the cyber system to the power system is quantified by the model. The practicability of the proposed data transmission mechanism is given by numerous cases.
