Are microgrid protection schemes based on traditional principles?
This paper presents a comprehensive review of the available microgrid protection schemes which are based on traditional protection principles and emerging techniques such as machine learning, data-mining, wavelet transform, etc. A categorical assessment of the reviewed protection schemes is also presented.
Do microgrids have protection challenges?
In this work, solutions to the protection issue in a microgrid that have been suggested in various studies are analyzed. This study examines the proposed protection challenges, such as auto-reclosure and coordination of protection equipment, associated to significant penetrations of embedded generation in distribution networks.
Are time-domain and communication-assisted protection schemes suitable solutions for Microgrid protection?
The key findings of the paper suggest that the time-domain and communication-assisted protection schemes could be suitable solutions to address the identified protection challenges in the microgrid. Index Terms—Distributed generation, distribution systems pro-tection, microgrid, microgrid protection.
How to protect a dc microgrid?
Different protection strategies for DC microgrid. 1. Calculate distance of the fault location using signal processing approach and impedance using Active Impedance Estimation method. To detect the fault location, transient part of current and voltage signal having high frequency is excerpted and send to the feeder.
What are the advantages and disadvantages of microgrids?
Microgrids develop many benefits such power factor correction, voltage and frequency regulation and also improve power quality in case of using a proper control strategy; in addition, microgrid faces operation and technical challenges, including system stability, voltage/frequency regulation, protection issues, and power quality .
Are over current protection devices suitable for AC microgrids?
Therefore, traditional over current protective devices are not suitable for protecting the AC microgrids. According to literature, in both grid-tied and island mode, there is consequential difference in fault current level and this fault current is perpetually changing due to the existence of distributed generation (DG) resources.
