The project Service-based Open-source Grid automation platform for Network Operation of the future (SOGNO) is creating plug-and-play, cloud-native, micro-services to implement our next generation of data-driven monitoring and control systems. It will simplify the life of distribution utilities by enabling them to optimize their network operations through open source to deliver cost-effectively, and seamless, secure power supply for their customers. SOGNO introduces the idea of grid automation as a modular system in which components can be added through time. This is in opposition to classical monolithic solutions.
SOGNO is maturing data-driven control services. The architecture is independent of the communication media but it has been designed originally to have 5G in mind and its edge cloud approach. By using the upcoming 5G mobile network standard they will be characterized by low latency and high availability.
Power system networks of the future will be composed of assets whose profiles may shift between loads, resources, and the ability to provide flexibility back to the grid. This will have a transformational impact on the operation of the distribution system and its relationship to transmission and utility generation. Reinforcing the current system is not sufficient to deal with the increasing complexity of distribution systems. Rather, we are at the cusp of needing deployment of advanced distribution management systems down to the low voltage network. These solutions can be implemented as centralized but even better as distributed architecture to better support the sparsity of distribution grids.
SOGNO – which means “dream” in Italian – facilitates network operators in the transition to a modular microservices-based control center software solution. Our vision is to integrate today’s SCADA systems with SOGNO and then to gradually move functionalities into microservices. As a result, SOGNO is not in opposition to classical solutions but it can be seen as an add-on that supports a flexible growth of the automation architecture. This allows operators to adapt faster with components that can be updated independently from each other while recognizing the “brown field” that most utilities continue to operate in. SOGNO provides system operators and automation software developers a pathway to the future through an open source framework that exposes open APIs that plug-in new automation functions, while supporting industry standards such as CIM IEC61970.
