Roadmap

The purpose of this part is to update, after each TSC meeting, the roadmap: https://github.com/powsybl/.github/blob/master/ROADMAP.md

Open loadflow supports now sensitivity analysis (DC and AC), with some improvements needed for HVDC management. As explained in last TSC, we have concentrated our effort on refactoring and performances to be able to deal with complex network configurations. Call for help to test the next release!

IIDM C++ Patch release v1.3.2. The IIDM version 1.4 will be supported early April.

Metrix C++ code has been merged. No release for metrix-integration for the moment.

Dynawo Luma is working on updating the network + topological changes after Dynawo and DynaFlow calculations.

Time series The work is going to be presented in the technical discussion.

Balances-adjustment From a CGMES control area and net positions we are able to perform a balances adjustment on two merged networks.

Eurostag The conversion has been migrated to Powsybl organization, and plugged on Powsybl version 4.0.1. The quality level has improved but Mathieu needs help to improve the conversion of some equipments.

Core Note that we are also working on a CNE export from security analysis results and on a power factory importer ([WIP] PowerFactory import by geofjamg · Pull Request #1653 · powsybl/powsybl-core (github.com)).

Technical discussion

Benjamin Horvilleur and Arthur Michaud, from Artelys (Home - Artelys), will present us their work on the future time series sore. Their work is followed by Jon and Paul. I will send you the presentation as soon as possible.
