Area Interchange Control as OuterLoop
Describe the current behavior
No support for Area Interchange Control
Describe the expected behavior
Ability to include Area Interchange Control (AIC) in OLF simulations. The classical methods of doing AIC in a load flow are:
- Though an OuterLoop
- Directly in the Newton-Raphson
We propose as a first step to implement the OuterLoop approach only. The feature can be enabled/disabled through OpenLoadFlowParameters.
Describe the motivation
Area Interchange Control is a classic feature of load flows - just like simulating ratio/phase tap changers. A quick google search reveals e.g. AIC is supported by:
Entso-e documents consider also AIC as a load flow option:
- EMF requirements section 4.8
-
ENTSO-E SKOS codelist in EDI Library also here:
cim:PowerFlowSettings.interchangeControlEnabled": "true"
In the PowSyBl ecosystem this can be achieved today using powsybl-entsoe/balance-adjustment module, which is a quite complicated and slow implementation. Integrating the feature directly in OLF as an OuterLoop allows for faster performance, and enables also simulating AIC in security analysis - while powsybl-entsoe/balance-adjustment approach is not suitable when simulating thousands of contingencies.
Extra Information
Requires https://github.com/powsybl/powsybl-core/issues/2883 to be implemented first in powsybl-core/iIDM
@jeandemanged can you please give a rough timeline on when this is expected to be implemented? thank you

Hi @amir-saadat,
I terms of timeline we expect:
- June 2024 release: area model definitions in powsybl-core/iIDM (https://github.com/powsybl/powsybl-core/issues/2883)
- (hopefully) September 2024 release: this AIC feature
