Advanced Clustering and Optimisation Techniques for Adaptive Protection in AC Microgrids With Hardware‐in‐the‐Loop Testing

Energy Science & Engineering
This study introduces an advanced adaptive protection approach for AC power systems, designed to address key limitations in current clustering‐based relay coordination methods. Using K‐means, hierarchical, and spectral clustering techniques, the proposed

Type-2 Fuzzy C-Means-Based Clustering-Decomposed Coordination of Directional Overcurrent Relays

Energies
Optimal coordination of directional overcurrent relays (DOCRs) in medium-to-large power systems constitutes a computationally demanding, mixed-integer, nonlinear optimisation problem whose complexity escalates rapidly with system size, making the ...

Enhanced real time coordination of distance and user defined over current relays

International Journal of Electrical Power & Energy Systems, 2018
Abstract Faults on the transmission lines are primarily cleared by pilot wire differential protection as well as from zone-1 and zone-2 of distance relays, depending upon their location on the lines. If the main distance relays fails to operate, then standard time inverse directional over current (DOCR) relays are set as backup protection in ...

Optimal overcurrent relay coordination: Balancing costs, time performance and generator placement in fault current limiter optimization

IET Generation, Transmission & Distribution
The integration of synchronous generators (SG) to the grid will present serious problems in some instances. The increase in fault current level is one of the most crucial issues, which causes miscoordination between directional over current relays (DOCRs)
