DSO interacting with heterogeneous DER in distribution grid

摘要

On one hand, DER companies are facing a need for productivity improvement along the whole activity chain from investment to maintenance healing towards standardization of equipment and control systems while on the other hand, the French DSO needs a wider monitoring and control ability of DER resources whose connection to MV networks is bursting: DSO related needs that are definitely at the beginning of what will be continuously evolving with Smart grids in the coming years; only standards could cope with this pace. The conjunction of standardization needs gave ERDF, the French DSO and MAIA EOLIS an opportunity to get deeply involved in a practical implementation of IEC 61850 standard improve drastically the monitoring and control interface between wind power plants and distribution networks dispatching and IT systems. In this frame, ERDF, MAIA EOLIS and EDF R&D experiment since 2015 a communication infrastructure based on Web service technology and IEC 61850 data model. Data exchanges between wind power plant monitoring and control system and ERDF ITs systems shall include I/O statuses, measurements, weather data, maintenance scheduling, active and reactive load scheduling programs and remote controls (set points, O/C commands, On/Off controls and automatisms etc.). This paper presents the project as a whole, the participating companies' motivation, details the technical issues (infrastructure, data model technology, cyber security issues, etc.) and stresses the standardization awaited outcomes.
