Open Source for Power Grids: The Business Model of a Service Provider - Nicolas Omont, Artelys

Generally speaking, open-source adoption requires the development of an ecosystem of IT service providers to develop, customize, support, and maintain the corresponding software. Power grid operators are not an exception to this rule. They have additional specificities like the requirement to coordinate closely so that they exchange a massive amount of complex information and run coordinated operational processes. Through the experience of Artelys as a service provider using extensively PowSyBl, a path to a sustainable ecosystem will be sketched out.

PowSyBl AC Optimal Power Flows - Nicolas Omont, Artelys

PowSyBl includes a framework to design AC Optimal Power Flows. It was used to develop Open Reac, dedicated to the voltage plan initialization needed when forecasting future grid states that are very different from historical ones, and a divergence analyzer, used to identify issues in data that prevent load flow convergence. Contrary to the other OPFs of PowSyBl (Open RAO and Metrix), these OPFs natively handle the non-linear equations of static power grid models, making them particularly suited to manage voltage constraints. The use of a tabular format makes it easy to prototype new OPFs. The roadmap involves the development of fully open-source OPFs based on Julia JuMP.

Workshop Preview: Using PyPowSyBl to Assess Transfer Capacitiy of New Electricity Interconnections - Fabrice GUY, RTE

Join us for a 15-minute workshop preview to learn more about this workshop.

Workshop Description:
Assessing the benefits of interconnection projects is one of the goals of ENTSO-E Ten-Year Network Development Plan (TYNDP). New electricity interconnections, by increasing power exchange capabilities between countries are key elements to make the energy transition happen in a cost effective and secure way. Being able to evaluate the increased power flows brought by a new interconnection project is then of major importance. To calculate this indicator (named ΔNTC: increase in Net Transfer Capacity), a tool chain based on pyPowSyBl (from Powsybl Linux Fundation Energy project) has been developed within an ENTSO-E working group and will be used for the next TYNDP. Based on a real HVDC interconnection project between France and Spain and publicly available data, we will illustrate the methodology used and all pyPowSyBl fonctionnalities involved through a Jupyter notebook: • Importing TYNDP2022 French and Spanish transmission grid model (in CGMES format) and merging them to build a common grid model, • Calculating yearly load flow on hourly basis, • Taking into account the impact of line tripping, • Calculating the ΔNTC brought by the interconnection project.

This LF Energy Project Webinar took place 3 June 2024.

Abstract:
Do you want to learn how to model and simulate an electrical network from scratch in under an hour?

Then welcome to this PowSyBl workshop, hosted by Rte, the French Transmission System Operator (TSO)!

During the webinar, you will discover the PowSyBl ecosystem as well as handle and study an electrical network through an interactive Python notebook.

PowSyBl is an open source project hosted by LF Energy, which offers a comprehensive set of features for electrical grid modelling and simulation. Among other advanced features, PowSyBl provides:
- A fully editable and extendable library for grid component modelling;
- Visualization tools to display your network;
- Grid simulation tools, such as power flows, security analyses (with or without remedial actions) and sensitivity analyses;

The framework is mostly written in Java, with a Python binding so that Python developers can access PowSyBl functionalities as well.

What you will learn during the webinar:
- For beginners: discover PowSyBl's functionalities through a quick general presentation and the notebook, without needing any expert coding skills;
- For advanced developers: master the skills to efficiently apply PowSyBl functionalities to your real-world scenarios.

Speakers:
Sophie Frasnedo, Software Engineer, RTE
Coline Piloquet, Software Engineer, RTE

"GridSuite and PowSyBl: an Open Source approach to develop advanced tools for grid analysis and simulation of power systems" was presented in the FOSDEM 2024 Energy Devroom by Jean-Baptiste Heyberger of RTE.

During these last two decades, transmission system operators (TSOs) have been facing profound changes such as penetration of renewables, DC networks, redefinition of European market mechanisms leading to major evolutions in the way to operate the electrical transmission grids. The goal of carbon neutrality implies that most of the challenges for TSOs are still to come. All those changes imply drastic changes in the way to perform grid analysis and have appropriate computation modules to perform efficient security assessment. Legacy tools are evolving slowly with low information about used approximations. RTE, the French TSO, believes that Open Source is the perfect answer to build power system tools in an efficient, flexible, transparent, and collaborative way. RTE has significantly invested in these Open Source tools and would like to share his experience with demo of tools currently in operation based on PowSyBl framework.
