, 2021 The concept of microgrids goes back to the early years of the electricity industry although the systems then were not formally called microgrids. Today, two types of microgrids can be seen: independent and grid connected. The protection requirement of these two types differs as the protection needs of an independent microgrid are intended for ...

Voltage-Based Frequency Synchronization for Phasor Measurements in Microgrid Protection
2023 IEEE PES/IAS PowerAfrica, 2023 The accurate measurement of current phasors is crucial for the reliable and effective protection of microgrids. However, the presence of harmonics and variations in the fundamental frequency due to the integration of inverter-based resources (IBRs), can ...

A Novel Protection Method for Single Line-to-Ground Faults in Ungrounded Low-Inertia Microgrids
Energies, 2016 This paper proposes a novel protection method for single line-to-ground (SLG) faults in ungrounded low-inertia microgrids. The proposed method includes microgrid interface protection and unit protection. The microgrid interface protection is based on the
