Abstract:
With the advancement of power electronics technologies, DC microgrids have emerged as a viable alternative to AC microgrids thanks to their higher reliability and power quality. The most important issues that limit the use of DC microgrids are related to the protection of these grids. Despite many studies on this subject, there are still major challenges in this area including the reliable detection of high impedance faults in DC microgrids. This paper presents a new method of high impedance fault detection in DC microgrids based on real and imaginary components of power. The proposed method is implemented using PSCAD software and Python programming language. The results demonstrate that the proposed method can detect high impedance faults without malfunctioning and issuing incorrect tripping commands during common events such as motor starting or load switching.
