How Baltic RCC is Using Open Source Technology to Overcome Energy Transition Challenges

The energy transition sweeping Europe presents a series of complex challenges for the region’s electricity networks. With the rise of renewable energy sources, electricity grids are becoming increasingly decentralized and interconnected across borders. Ensuring stability in this evolving landscape is the responsibility of Regional Coordination Centres (RCCs), such as the Baltic RCC, which oversees grid security and operational efficiency in the Baltic region. Facing a shifting energy ecosystem, the Baltic RCC has adopted innovative, open-source solutions to enhance grid stability, network model management, and compliance with European Union regulations.

Challenges in a Rapidly Evolving Energy Landscape

As Europe shifts toward a sustainable energy future, the electricity grid must adapt to accommodate the intermittent nature of renewable sources like wind and solar. For the Baltic RCC, this transition poses significant challenges:

• Complex Network Modeling: Each Transmission System Operator (TSO) across Europe has traditionally managed its own network models. To create a unified, Pan-European model, the RCCs must merge these independently developed systems, a complex process requiring precision and vast resources.
• Regulatory Compliance: The EU’s regulation 2019/943 mandates that RCCs maintain a Pan-European network model capable of assessing grid stability and handling potential outages without causing cascading failures.
• Avoiding Vendor Lock-In: Traditionally, many energy organizations have relied on proprietary software solutions, which often come with high licensing costs and long-term dependencies. The Baltic RCC wanted to avoid these limitations, seeking a flexible, scalable, and community-driven solution.
• Lack of Internal Expertise: Initially, the Baltic RCC lacked the internal expertise needed to develop and maintain an open-source grid management system. This challenge was particularly relevant given the complexity of the tasks at hand, from grid modeling to conducting simulations and “what-if” scenarios.

An Open Source Solution with LF Energy

Rather than relying on proprietary software, the Baltic RCC took a bold step towards adopting open-source solutions. At the heart of this initiative is its partnership with LF Energy, a foundation supporting the development of open-source software to accelerate the energy transition. The Baltic RCC’s core technology stack leverages LF Energy’s PowSyBl (Power System Blocks) project, which provides tools for grid modeling, simulations, and analysis.

PowSyBl offers crucial functionalities for managing network models and conducting load flow calculations, enabling the Baltic RCC to create a working Pan-European model that adheres to regulatory requirements. Central to this system is PyPowSyBl, a library used to manage Common Grid Model Exchange Standard (CGMES) files—an essential format for sharing and merging network models between TSOs.

Key Components of the Baltic RCC’s Open Source Approach

The Baltic RCC’s open-source architecture is built around a modular design, with several critical components working in tandem to ensure grid security and compliance:

• Data Exchange: Managed through OPDE (Operational Planning Data Environment) and RabbitMQ, ensuring reliable and secure message brokering across different systems.
• Data Storage: Implemented using Minio, an open-source, S3-compatible object storage platform that supports the vast amount of data involved in modeling and simulations.
• Visualization: The system utilizes Kibana, an open-source tool for monitoring and visualizing processes, enabling real-time insight into the grid’s performance and potential issues.

The Role of Collaboration

An essential part of the Baltic RCC’s success has been its collaboration with RTE International, an organization with extensive experience in open-source tools for grid management. This partnership allowed the Baltic RCC to access proven, well-maintained tools for conducting load flow analysis, ensuring that the open-source solutions were not only reliable but also scalable for future needs.

Moreover, the Baltic RCC adopted a community-driven development model, which allows them to continuously improve and evolve the system with input from a broader group of stakeholders, including other RCCs and technology experts. By fostering a community around the project, they were able to pool knowledge and resources, avoiding the pitfalls of vendor lock-in and ensuring long-term viability.

Results and Long-Term Benefits

The open-source approach employed by the Baltic RCC has yielded significant results, particularly in overcoming the complexity of grid modeling and regulatory compliance. Key outcomes include:

• A Pan-European Network Model: Using PyPowSyBl’s capabilities, the Baltic RCC successfully developed a Pan-European network model that supports detailed stability analysis. This model allows for comprehensive “what-if” scenarios, ensuring the grid can handle outages without cascading failures across borders.
• Avoidance of Vendor Lock-In: By choosing open-source tools, the Baltic RCC retained full control over its technology stack, avoiding the long-term costs and dependencies often associated with proprietary software solutions. This independence allows for greater customization and adaptability as the energy landscape continues to evolve.
• A Foundation for Future Development: The modular, open-source nature of the Baltic RCC’s solution provides a strong foundation for future development. As new challenges arise and technologies emerge, the system can be extended and improved with input from the wider community, ensuring it remains relevant and effective.

Fostering a Collaborative Future

While building a community around open-source grid management tools is an ongoing challenge—particularly in an industry where concerns about security and compliance are paramount—the Baltic RCC has made significant strides in engaging other RCCs and solution providers. As the system becomes more advanced and stable, interest and contributions from the broader energy sector are expected to grow.

The case of the Baltic RCC underscores the transformative potential of open-source solutions in addressing the challenges of the energy transition. By leveraging LF Energy’s PowSyBl project and building a collaborative development community, the Baltic RCC has created a scalable, compliant, and future-proof solution that can support Europe’s move towards a more sustainable and resilient energy grid.
