Virtualized Services in Smart Grids
How can the technological implementation of scalable and flexible services in smart grids be achieved at the substation level?

The energy transition and the increasing decentralization of power generation necessitate the involvement of distribution networks in addressing the challenges of planning and controlling the electricity system. This requires the adoption of suitable monitoring and control mechanisms and is closely linked to the ongoing digitalization of the energy sector. The integration of information and communication technologies (ICT) has led to a cyber-physical energy systems (CPES).

A CPES combines the physical components of the energy system with computational technologies and networks. Within such a system, sensors, actuators, and control systems are deployed to capture, transmit, and analyse data regarding the state and operation of the energy system. This data serves as the foundation for providing functionalities and services at the distribution network level, which contribute to improved system management and enhanced ancillary services. These services, often referred to as grid service, include, for instance, state estimation, protection functions, voltage regulation, and redispatch measures.

Traditional local substations within distribution networks require manual interventions and offer limited data and control capabilities. In contrast, modern digital substations enable more precise and automated system management through real-time data transmission and remote monitoring. The increased flexibility and adaptability of digital technologies support more efficient operations and the optimization of grid services. Paradigms such as edge, cloud, and fog computing have become integral components of modern digital systems. These paradigms address the required flexibility and adaptability through concepts such as virtualization, orchestration, and process management. Figure 1 provides a schematic representation of a CPES with virtualized Services (VF) at the edge of the energy system.

Flagship Projects

i-Automate and i-Autonomous

The projects i-Automate and i-Autonomous addresses the virtualized provision, orchestration, and management of services at the substation level. The project used core technologies such as containerization using Docker or CRI-O, along with Kubernetes as orchestration software, and tests these on industrial hardware within a "hardware-in-the-loop" approach.

Additionally, applications of existing engineering processes, such as IEC 61850, challenged to perform automated approaches to them. This includes extending the IEC 61850 standard description language with new elements and experimenting with automated approaches for fully automated service selection, configuration, parameterization, and execution on distributed devices.

The overarching goal is to enhance transparency, controllability, and resilience in smart grids through the flexible deployment of virtualized services. Current and future work focuses on adapting digital paradigms to the needs of smart grids.
