Abstract: A micro-grid is an aggregation of electrical and heat loads and small capacity micro-sources operating as a single controllable unit at the low or medium voltage level. Nowadays, digital telecommunications have been used in many industrial applications which micro-grid protection has also been benefited. Occurred challenges in distribution network caused by micro-grids presence, telecommunication and distribution engineers failure in recognizing the protection schema requirements and telecommunication networks restrictions always have made problems in implementation and utilization of the protection schema. In this paper, in addition to introducing types of telecommunication technology and protection system, problems existed in applying the digital telecommunication network is also evaluated for protection purpose in micro-grids and some points which a schema should consider for teleprotection system to make improvement and dependability is also explained.
