1 Scope
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 systems with a controllable power converter . It defines the IEC 61850 information models to be used in the exchange of information between these power converter -based 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.
These power converter -based DER systems 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.
The namespace of this document is:
“(Tr) IEC 61850‑90‑7:2012”
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...
