The coordinated or selective power system can be considered as a sequence procedure
among two protective devices installed in series and having certain features. The …

The coordination of directional overcurrent relays (DOCRs) in meshed power grids with
multiple sources is a constrained optimization problem, which has been stated in recent …

This paper proposes a robust protection coordination scheme of directional overcurrent
relays (DOCRs) for multiple network topologies in the presence of on-load tap changers …

Directional overcurrent relays are often used in the protection of electrical power
transmission and distribution systems. These devices are installed along the network, and …

Power system faults can often result in excessively high currents. If sustained for a long time,
such high currents can damage system equipment. Thus, it is desirable to operate the relays …

In the process of determination of breakpoints for overcurrent relays (OCR), different sets
with equal number of OCRs can be selected as minimum breakpoint set (MBPS). Therefore …

Coordination of directional relays in large-scale power systems that are multi-loop structured
is a complicated and time consuming problem. Therefore, determination of the directional …

Determination of the minimum breakpoint set (MBPS) is essential for optimum coordination
of directional protection relays. However, in modern large-scale power networks, this task …

The current study presents a zero-one integer programming approach to determine the
minimum break point set for the coordination of directional relays. First, the network is …
