microgrid is a developed form of a distribution system, which is integrated
with a set of different types of distributed generation (DG) to supply local
demand. In spite of that microgrids have many advantages as they increase
reliability, raise efficiency, decrease feeder losses and voltage sag correction.
However, there are many technical challenges faced, one of them is the
protection of microgrid. Conventional protections have been made for radial
distribution systems configuration. Where supplying source has one
direction and the power flow is defined. The DG penetration converts the
distribution network to a multi sources system causes a bidirectional power
flow. Also, the most of DG uses a DC to AC converter which limit the fault
current level. Therefore, a suitable protection scheme for microgrid ought to
be designed to protect a microgrid from any disturbances may occur for both
modes of operation grid-connected and islanded. The purpose of this paper is
to summarize the challenges and problems facing microgrid protection. As
well as the most strategies to date are presented with a discussion of their
basic principles of operation to solve these problems. Finally, some
conclusions and suggestions for microgrid protection in the future are
presented.
