Documentation

• Improve our functional documentation
• More and more user stories
• More and more tutorials
• A more logical plan for the website

Demonstrator

We have started to create a web-based demonstrator packaged as docker images to show the world what PowSyBl is: https://demo.powsybl.org/study-app/. It is available for everyone to experiment, with some great features:

• Import networks (we are working on TSOs part of the European network)
• Display networks on a map using CIM-CGMES Geographical Location (GL) profile
• Display substations (single line diagram) using CIM-CGMES Diagram Layout (DL) profile
• Apply simple modifications to the network topology (tap changes, setpoints changes, status of switches)
• Run power flows and display the calculation results
• Run security analyses and display violations on the network map and in a synthetic table

Converters

CIM-CGMES

→ Importer

• End of basic importer (operational limits and HVDC conversions improvement)
• Diagram layout (DL) profile management
• Geographical location (GL) profile management
• Generation and Load Shift Keys (GLSK) and Contingency list, Remedial Actions and additional Constraints (CRAC) management
• Merging through the merging view

← Exporter

• Incremental export: Export back to a CIM-CGMES file, a network imported from a CIM-CGMES file.
• Full export: Export to a CIM-CGMES file, a network imported from any supported format.

XIIDM

→ Importer

• Version management (backward and forward compatibility).
• The C++ implementation is almost finished and will be in open source in February 2020. Then, we have planned to work on version management.

Grid modeling

The backward compatibility management has been done last year. We have now a strong basis to change the core network model:

• Three windings transformers modeling improvement: almost done.
• HVDC modeling improvement
• Operational limits modeling
• Linear and non linear shunt compensators
• Extenstions for automatic generation control and for monitoring
• DC network modeling (maybe for 2021)
• Merging view when several networks are merged.
• A listener that records events occurring on the network has been implemented. We have planned to functionally validate it.

Simulators

• Integration of Dynawo: work in progress.
• Improving our open load flow used for tests, experimental and collaboration purposes. For more information, please read the README file.

Data management

• A persistent implementation of the network core model (IIDM) based on Apache Cassandra
• A persistent implementation of the triple store
• A Persistent implementation of the extensions
• A permissions and quotas management in the AFS
• A log collector in the AFS

Viewing

• Voltage level view: display clean, pretty and interactive drawings of voltage levels
• Substation view: display clean, pretty and interactive drawings of substations
• Improvement of the graphical charter of electro-technical components
• A geographical web view of the network

Grid Study Environment

• A nice view of dependencies between objects
• Provide the new features of AFS in the Grid Study Environment

High level services

• Package and distribute computation services based on spring, as docker images

Functional tests

We plan to validate a CIM-CGMES based workflow, focusing on the functional validation, the computation time and the memory consumption. The CIM-CGMES workflow consists in importing networks (also called Individual Grid Model), running a power flow, merging the networks (topologically at least), running a power flow on the merged network (also called Common Grid Model), applying modifications and exporting the updated network(s).
