This part of IEC 61850 describes the functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER system s with a controllable power converter. It defines the IEC 61850 information models to be used in the exchange of information between these power converterbased DER systems and the utilities, energy service providers (ESPs), or other entities which are tasked with managing the volt, var, and watt capabilities of these power converter-based systems.<\/p>\n

These power converter-based DER system s can range from very small grid-connected systems at residential customer sites, to medium-sized systems configured as microgrids on campuses or communities, to very large systems in utility-operated power plants, and to many other configurations an d ownership models. They may or may not combine different types of DER systems behind the power converter, such as an power converter-based DER system and a battery that are connected at the DC level.<\/p>\n

The namespace of this document is:<\/p>\n

\u201c(Tr) IEC 61850-90-7:2012\u201d<\/p>\n

The namespace “IEC 61850-90-7” is considered as “transitional” since the models are expected to be included in IEC 61850-7- 420. Potential extensions\/modifications may happen if\/when the models are moved to International Standard status.<\/p>\n

Only the new data objects and CDCs which are represented in bold-italic font<\/i><\/b> will be tagged with this namespace name. The others should still refer to the namespace where they are primarily defined.<\/p>\n

\n

NOTE The term power converter is being used in place of \u201cinverter\u201d since it covers more types of conversion from input to output power:<\/p>\n<\/blockquote>\n
