DER RFI (request for information)

The standard under way for distributed energy resources will be as good as we receive the crucial requirements from the domain experts.

You as a domain expert can provide your input through this webpage. The input will be collected and - if useful - be used as input to the ongoing standardization process by Karlheinz Schwarz (SCC).

We are looking for input for the following domains:

photovoltaic systems
fuel cell systems
combined heat and power
diesel gensets
et cetera
as well as distribution feeder equipment

We would appreciate your valuable input.

Note that the definitions of information models and information exchange methods for wind power, hydro power and substation automation and integration have already been published!

Two examples of the information models we have already defined for photovoltaic systems are:

Photovoltaic Panel Characteristics

Status Information

StrStow (Panel in stowed position)

Settings

DERId (Master Resource Id of DER device)
MdulCnt (Number of modules per panel)
PvArea (Panel area meters**2)
PvTilt (Panel elevation - degrees from horizontal)
PvOrien (Panel azimuth - degrees from true north)

Photovoltaic Array Characteristics

Settings

DERId (Master Resource Id of DER device)
PanlCnt (Number of panel per string)
StrgCnt (Number of parallel strings per sub-array)
SubACnt (Number of parallel sub-array per array)
PvArrArea (Array area: meters**2)
PvArrWRtg (Array power rating: W
PvArrAziShade (Array of obstruction elevations vs azimuth)

We are looking for your requirements: Please fill out the fields below or send your complete list ... Thanks.

source and destination of information	kind of information	communication network	rate of exchange
example: Photovoltaic park controller to operator and maintenance stations	measurements of current power production of each array with timestamp	IEC 60870-5-101	on request; spontaneous when a specific threshold is reached; cyclic

If you have a more comprehensive list of signals to be exchanged you may send me the complete list as well.

After you have filled out all fields of this page please send us the request .
