Overcurrent and Directional Overcurrent Protection for Microgrid
Andalasian International Journal of Applied Science, Engineering and Technology, 2023 Microgrids will become common in future electrical distribution networks. Numerous operating modes that occur in microgrids make the development of protection schemes and settings challenging. This paper aims to develop a simple protection scheme for the Microgrid IEC Benchmark without any expensive equipment such as communication apparatus.
