Just published: IEC 61850-7-420 Basic Communication Structure – Distributed Energy Resources And Distribution Automation Logical Lodes

IEC TC 57 just published one of the most crucial parts of the standard series IEC 61850:

This second edition of the 548 pages long bilingual standard (EN/FR) has been developed over a period of - I guess more than 10 years - taking into account the experience with IEC 61850 in general and with distributed power systems.

Now it is time to implement and use the standard in conjunction with the other core parts like IEC 61850-6, 7-1, -7-2, -7-3, and 7-4.

IEC 61850 - Model Extensions To Support Microgrids

IEC TC 57 just published a proposal for a new work:

57/1888/DC

Model extensions to IEC 61850 to support microgrids

From the preamble:

"An important market trend is to enable the operation of DER in islandable mode supplying a local process such as campus, buildings, industries, …. Thus it is important to complement the existing and/or coming IEC 61850 series of standards to support such an operation mode, including the protection of considered assets, the management of their transitioning between grid-tied and islanded mode, but also to the support the management of frequency, voltage, and quality of supply to the process. ..."

Comments to the proposal are welcome by 2018-07-20 at the latest.
