Standardization of power system protection settings using IEC 61850 for improved interoperability [PDF]

, 2013
One of the potential benefits of smart grid development is that data becomes more open and available for use by multiple applications. Many existing protection relays use proprietary formats for storing protection settings.

Adaptive directional overcurrent relaying scheme for meshed distribution networks [PDF]

IET Generation, Transmission & Distribution, 2018
Distribution networks are evolving into active meshed networks with bidirectional power flow as the penetration of distributed generation (DG) sources is increasing. This necessitates the use of directional relaying schemes in these emerging active distribution networks. However, conventional directional overcurrent (OC) protection will not be adequate

Influence of fault-ride-through requirements for distributed generators on the protection coordination of an actual distribution system with reclosers [PDF]

, 2017
This paper analyses the existing protection scheme of a real distribution system with distributed generators, in Greece. Network protection utilizes three successive reclosers at the main trunk and fuses at the laterals.

Optimal Linear Protection Scheme of Inverter‐Based Distributed Energy Resources: Meeting Fault‐Ride‐Through Requirement

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper presents a new two‐stage protection strategy for active distribution networks that not only addresses selectivity constraints along protected lines but also incorporates fault‐ride‐through (FRT) requirements of inverter‐based distributed energy resources (IBDERs). The proposed coordination strategy (PCS), which distinguishes it from previous
