Time-series modelling of IEC 61850 GOOSE communication traffic between IEDs in smart grids -- a parametric analysis
Résumé
Nowadays power grids are intelligent since their protection, supervision and control areheld by a communication network through which different Intelligent Electronic Devices (IEDs)are interoperating. To design and maintain an efficient Substation Communication Network (SCN)with high transmission quality, developing a unitary mathematical model of the SCN data traffic asunderlying paradigm of any control design approach is an important issue. In this paper, a stochasticrepresentation of data traffic is derived, and a parametric analysis over the communication channelcharacteristics is presented. The identification method is illustrated on an electrical distributiongrid containing two renewable sources which are exchanging information by means of IEC 61850GOOSE (Generic Object-Oriented Substation Event) communication protocol in the context of asimple distributed reactive power control. The simulation and code process of both electrical andcommunication configurations are performed in MATLAB®/Simulink®.
