AC Microgrids Protection: A Digital Coordinated Adaptive Scheme [PDF]
Applied Sciences, 2021 A significant challenge for designing a coordinated and effective protection architecture of a microgrid (MG) is the aim of an efficient, reliable, and fast protection scheme for both the grid-connected and islanded modes of operation. To this end, bidirectional power flow, varying short-circuit power, low voltage ride-through (LVRT) capability, and ...

Reinforcement Learning for Optimal Protection Coordination
2018 International Conference on Smart Energy Systems and Technologies (SEST), 2018 The design of reliable protection systems is essential in order to guarantee the secure operation of power systems. The coordination of the response of protective equipment under fault conditions is a fundamental problem which is usually formulated as a non-linear optimization problem with the objective of minimizing the total operating time of the ...

An Optimization-based Protection Strategy in Active Distribution Network using Double Dual-Setting Directional Overcurrent Relays to Increase DG Penetration [PDF]
International Journal of Research and Technology in Electrical Industry, 2023 Coordination between protection devices is one of the important issues in any protection scheme of an electrical power system. The tendency to increasingly use distributed generation has jeopardized the selectivity of overcurrent relays in active ...

Minimum income protection and EU coordination [PDF]
European Journal of Social Security, 2018 A number of studies suggest that the Europeanisation process is having a profound impact on national labour market policies. Nevertheless, rather little research has been devoted to the development of social assistance schemes across countries and over time.

Protection Coordination Index Assessment Using Fuzzy Logic Controller
Energies, 2022 This paper proposes the assessment method of the protection coordination index (PCI) for overcurrent protection relay and upstream relay. The protection coordination index is an indicator of how properly the equipment is protected by protective relay ...

An Adaptive Overcurrent Coordination Scheme Withstanding Active Network Operations
IEEE Access, 2022 This paper aims to present a centralized adaptive protection scheme (APS) for the directional overcurrent relays (DOCRs) considering system dynamics such as load demand variations, topology changes and DGs to mitigate the above-mentioned effects.
