Owing to the unavailability of official release on the microgrid standard as yet at home and abroad， this paper is intended to make some suggestions along these lines. An analysis is made of foreign standards for interconnecting distributed resources with the power system and those for power quality， distribution networks， PV or wind power in China. According to the typical and operation characteristics of the microgrid， a proposal for developing the microgrid standard system is presented for future research on the microgrid.
