*5.2. MGMS Communication Standard Development*

The development of relevant standards introduced in Section 3 is a prerequisite to meet wireless technologies in MGMS. For instance, WirelessHART in [68] was noticed facilitating IEC 61850 in the distributed generation sector. A communication stack of IEC 61850, which is the OSI model, is changed and information model and exchange mapped to the wirelessHART protocol. However, it could not meet time limitation requirements of the standard, and the authors referred to solving this weak point to future work. This practice shows that since the most serving MGMS communication standard is IEC 61850, the communication stack of this standard should consider technology developments of wireless communication concerning their coordination with new trends in MGMS.
