Adaptive grid resilient based protection method for multi fault scenarios in medium voltage quintuple DC microgrid system.

Multi-microgrid systems offer a versatile solution to many of the challenges including issues on power glitches, grid flow optimization, stability and protection system malfunction faced by traditional centralized power grids. By enhancing resilience, integrating renewable energy, improving efficiency, and supporting economic and environmental goals, they represent a forward-looking approach to modern energy management. Despite of technological progress in fault current detection, significant challenges oriented to false tripping and protection blinding in multi- microgrid structures compared to single microgrid topology still remain unresolved.

An advanced graph algorithm-based protection strategy for detecting kilometric and cross-country faults in DC microgrid.

Low voltage DC microgrids (LVDC) are on rise, because of increase in usage of electronics-based utility loads. However, the protection and safety aspects of these grids remain unresolved due to the fault current magnitude, unnecessary tripping, and blinding of protection. In this paper, an adaptive differential protection system incorporated with an advanced graph algorithm is proposed for DC microgrid.
