3)      Flow decomposition

4)      Single line diagram

Roadmap

core      

1) AMPL solver

2) Remplace half line with dangling line in a tie line -> breaking change

3) Support of sub networks

4) Support of voltage drops in short-circuit API

5) Network modifications serialization

6) Rework on scalable

7) Move merging view as deprecated

8) Automatons support

9) New limits: angle difference between 2 buses, power transfer corridor

open loadflow

1)      Support of bus and bus bar section contingency

2)      Refactoring of voltage controls because of switch open or close during contingencies or actions.

diagram

1)      standardizing sld/nad APIs, code coverage improved             

2)      sld: zone diagram, best effort for display bugs

3)      nad: Restricting oscillation of strongly connected points

dynawo

1)      New models: Generator pq, fixed ration transformer model, line model

2)      Merge loads feature

3)      Fix output of security analysis

enstoe

See you tomorrow !
