Utilizing Network QoS for Dependability of Adaptive Smart Grid Control

摘要

A smart grid is a complex system consisting of awide range of electric grid components, entities controlling powerdistribution, generation and consumption, and a communicationnetwork supporting data exchange. This paper focuses on theinfluence of imperfect network conditions on smart grid con-trollers, and how this can be counteracted by utilizing Qualityof Service (QoS) information from the communication network.Such an interface between grid controller and network QoSis particularly relevant for smart grid scenarios that use thirdparty communication network infrastructure, where modificationof networking and lower layer protocols are impossible. Thispaper defines a middleware solution for adaptation of smart gridcontrol, which uses network QoS information and interacts withthe smart grid controller to increase dependability. In order toverify the methodology, an example scenario of a low voltagegrid controller is simulated under imperfect network conditions.
