Hi everybody,

Our next TSC meeting will be on February 23^rd.

For this public meeting, it would be great if we follow these items:

Release of powsybl-core (4.0.1) on February 12^th, please refer to the release notes to know what the release will contain: Release v4.0.0 · powsybl/powsybl-core (github.com) + Release v4.0.1 · powsybl/powsybl-core (github.com)

This was a major release and our first release in Java 11.

Only one fix has been performed about ratio tap changer validation (4.0.1).

The Next Release will be on the 31^st of March. We hope to have as new functionalities:

-          A new security-analysis API (expected) ;

-          CGMES SV node/breaker export (expected) ;

-          A new sensitivity-analysis API (postponed for the moment) ;

-          A new PSSE conversion ;

-          CGMES Control area conversion.  

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] we support now a DC implementation of the sensitivity API (but we don’t support factors by contingency) ; we have decided to spend time on refactoring and performances. 

- [Core] We want to work on a new sensitivity-analysis API directly in the powsybl-open-loadflow to validate the design for powsybl-core.

- [Metrix] the Java part has been merged but the C++ part has a Sonar confirguration issue. Documentation has been merged.

- [Dynawo] Luma is working on the dynawo and dynaflow integrations: reporting?

- [Time series] the time series module cannot be moved out of powsybl-core because of a dependency in simulation-api.

- CGMES 3.0: we have the test cases and we will start to work on that after the control area conversion.

Other subjects? Sylvain? Sébastien?

Technical discussion

- Move the simulation-api out of powsybl-core ;

- Move the Eurostag export from IPST repository to powsybl.

If you have subjects, do not hesitate to send it to me.

Hi everybody,

There is a call for proposal for the LFE Spring Summit. If you want to present something, let me know.

Hi everybody,

Our next TSC meeting will be on January 28^th.

For this public meeting, it would be great if we follow these items:

Release of powsybl-core (4.0.0) expected on 3^rd of February, please refer to the release notes to know what the release will contain: Release v4.0.0 (expected-date: 2020-02-03) · powsybl/powsybl-core (github.com)

This is a major release.

The Next Release will be on March 31^st. We hope to have as new functionalities:

-          A new security-analysis API ;

-          CGMES SV node/breaker export ;

-          A new sensitivity-analysis API ;

-          And more…

Roadmap

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

- Gaël Macherel (Artelys) is still working on the openloadflow around sensitivity calculation. A first beta version of the DC sensitivity calculation will be available in the next release (maybe excepted HVDC sensitivity factor and reference functions for N-K simulations).

- We are working on a new sensitivity-analysis API directly in the powsybl-open-loadflow (Geoffroy) ;

- A new repository powsybl-metrix has been created and work has started (Mathieu) ; the Java part will be okay after the review process but it seems that the C++ part will not have the expected quality level (test coverage, translation, documentation, sonar issues, etc.) ;

- Sylvain is going to work on a schematic vision of the network for analysis purpose. Florian proposes to work a little bit on Cytoscape. In CGMES, we have a lot of voltage regulations that can be confictuous. We are looking for a network vizualisation that show them (switched shunts, regulating ratio tap changers, generators, static var compensators) ;

- Luma will work on the dynawo and dynaflow integrations ;

- Arthur Michaut and Benjamin Horvilleur (Artelys) are going to work on time series and  it could lead to the future “time-series-store” that we need in a micro-service architecture in order to deal with time series.

Other subjects ?

Technical discussion

It would be great if we have a discussion on management of networks that differ just from a few number of equipments (for network planning).

If you have subjects, do not hesitate to send it to me.

Hi everybody,

Our next TSC meeting will be on December 3^th.

For our third public meeting, it would be great if we follow these items:

Release of powsybl-core (3.8.0) expected on 2^nd of December, please refer to the release notes to know what the release will contain: https://github.com/powsybl/powsybl-core/releases

Open discussion if needed. This release is more a fix release but with some breaking changes.

The Next Release will be on January 13^th. This release will be more consequent with:

-          New concept of Boundary for Dangling Line and Tie Line ;

-          New operational limits API (maybe) ;

-          CGMES SSH export ;

-          CGMES SV node/breaker export (maybe) ;

-          New Contingency API.

Roadmap

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

- Alliander (https://www.alliander.com/nl/) is still discussing with us and with Plasma team to build a network model manager. It seems that they will use the single line diagram.

- Gaël from Artelys (https://www.artelys.com/) is working on the openloadflow around sensitivity calculation. A first beta version of the DC sensitivity calculation (with and without contingency) is expected in January.

- We are going to work on a new sensitivity API.

- A new repository powsybl-metrix has been created : Metrix, a simulator from RTE and uses by Imagrid project is going to be open source.

- Sylvain is going to work on a schematic vision of the network for analysis purpose.

- We still have an issue of design in dynawo integration.

Other subjects ?

Technical discussion

It would be great if we have a discussion on log management in Powsybl.

For next TSC meeting, do not hesitate to send me subjects days before !

Hi TSC members, hi Powsybl community,

I have just received that from Naomi, who asks for an answer for tomorrow ! The idea is to have a short presentation in the Open Source Summit Japan in the beginning of December. I think we have to make it ! It will be great to separate our Powsybl presentation in a short presentation of the library and in 2 demos of projects that use Powsybl in the model layer.

I was thinking about open source projects :

-          FARAO https://farao-community.github.io/

-          GridSuite https://github.com/gridsuite

But maybe we can also have other demos ! If you are interested in presenting what you are doing with Powsybl, please contact me.

Best regards,

Anne

Hi everybody,

The next TSC meeting will be on November 5^th (and not on next Thursday).

For our second public meeting, it would be great if we follow these items:

Next release of powsybl-core (3.8.0) expected on 25^th of November, please refer to the draft release notes to know what the release will contain: https://github.com/powsybl/powsybl-core/releases

Open discussion if needed.

We can also discuss about powsybl-core 3.7.1 as a feedback if needed. 

Roadmap

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

-          In last TSC meeting, we discuss about CGMES roadmap. We have been contacted on Spectrum last week by Alliander (https://www.alliander.com/nl/). They want to use Powsybl to import a EQ profile in node/breaker (only) and display a single line diagram. Maybe, it could be great to add in the roadmap a CGMES conversion with default values for SSH profile. Thanks Luma for your help !

-          We are going to work with Artelys (https://www.artelys.com/) on the openloadflow around sensitivity calculation.

-          Other subjects ? Feel free to send me emails, I will update the items.

Technical discussion

-          Geoffroy is going to make a demo of GridSuite ! Feel free to invite other  people to this TSC meeting.

-          Mathieu, what about py-powsybl status ?

For next TSC meeting, do not hesitate to send me subjects days before !

Hi TSC members,

The LF Energy asks me to have a roadmap for 2020 with the main features for PowSyBl organization. Please take a few minutes to complete the following file:

https://github.com/powsybl/.github/blob/master/ROADMAP.md

You can also send me an e-mail with the roadmap elements.

I also have to present in the next TAC (Technical Advisory Council, next Tuesday) our main goals. As an example, one of our goals is to have a CIM-CGMES based workflow that can import IGMs, merge them, make some modifications and export the updated European network in one or several CIM-CGMES files.

Thanks a lot.

Anne.
