Protection coordination in active distribution grids with IEC 61850.

This paper presents an adaptive protection scheme developed for distribution networks that include large number of Distributed Energy Resources and are capable to dynamically change configuration, i.e. active in nature. The system is based on a centralized controller running the real-time analysis of the data received from the field Intelligent Electronic Devices and communicating with IEDs by means of IEC 61850 communications.
