Why CDPSM ? What is it ?

• CIM was used at transmission level since 2000, and the profile was named “Common Power System Model”

• CDPSM was created to insure that Distribution needs were covered

• CDPSM will enable the information exchange between TSO and DSO

CDPSM 3

• Aims to Model Distribution Networks (MV, LV)

• Balanced, Unbalanced

• These Distribution Networkswill be exchanged in global, differential model

• The syntax used is RDF

• Load Flow calculation will be run upon these conforming data sets

• Node/Breaker & Bus/Branch

Keep it simple first, but preserve evolutivity

CDPSM Ed 2 : What has been done?

• Use Cases

• Gap Analysis between CGMES and CDPSM needs

• CIM issues

• UML Profiling and Document Generation

• The CDPSM UML Tool chain

• Data Conversion from 2011 CDPSM 1.0 IOP test to CDPSM Ed 2.0

CDPSM 11


Use Cases (What has been done?) Use of 62559-2 IEC Use Case Template

Name of Use Case Short description Actors General

remarks

DSO provides its power system

models to TSO

In order to calculate the TSO grid power

flow, the DSO provides to TSO an aggregate

view of its power system model, including

the related states and measurements.

TSO

DSO

A customer provides its DER

plant power system models to

DSO

A DER connection to Distribution grid

request is supported by the description of an

aggregate view of the DER plant power

system model

DSO

DER

Could also be

applied for

“operational

planning” and

“network

operation” ?

DSO1 and DSO2 mutual

exchange their power system

models

DSO1 and DSO2 mutual exchange their

power system models in order to manage

the grid in case of outages on a boundary

feeder

DSO1

DSO2

TSO and DSO provides their

power system models to a third

party

TSO and DSO provides their power system

models to a third party in order to perform an

ex-post analysis of a power quality issue (i.e

Voltage Dips)

TSO

DSO

Authority

DSO/DNO internal information

exchange

A DSO/DNO exchanges various information

or data between different systems within the

company

DSO or

DNO

DNOs provide their power system

models to DSO

In order to perform network planning,

various analyses, outage management, etc.,

of the whole distribution grid, the DSO needs

power system models of the subordinate

DNOs grids.

DSO

DNO

DNOs own and

operate a part

of the whole

distribution grid

for which the

DSO is

responsible of

(Slovenian

case).

Feeder task force status report

• Approx. 5 conference calls until now

• Approx. 10 people actively participating

• First objective is to gather as many use cases and requirements as possible from DNOs/DSOs

• Currently in the process of reviewing different requirements that havebeen expressed by different participants and also possible solutions

• Our aim is not to modify the UML model significantly

• We always have to have backward compatibility in mind

Feeder modelling – some open issues

• What is the start of the feeder (The breaker, the terminal) ?

• Where does the feeder end (with a substation, a sectionalizer) ?

• What are the rules in a meshed network vs a radial network?

• Does it contain equipment ?

• Does it associate with the Bay ?

• What are the rules in a LV network ?

• What are the rules when using the Line class vs the feeder class ?

• Where is the feeder class derived from?

• Does this solution support all our requirements?

CDPSM 23


Conclusion

This work will support DSO Network Modeling issues• Its goal is to clarify what are :

• DSO requirements• Common TSO/DSO requirements• TSO/DSO information exchange requirements

• Its goal is to get the most of Vendor Tools• Minimization of specificities

• A good standard can’t be defined without good requirements• DSO representatives are welcome to join IEC TC57

• Our aim is to walk the talk…
