Smart Grid Testing “Smart Grid Testing” group applies industry-oriented research approach to solve complex problems with a focus on real-time systems, co-simulation of multimodal energy systems, flexibility coordination and modular engineering processes. Supported by an extensive laboratory infrastructure, holistic testing and validation with hardware-in-the-loop and co-simulation can be carried out.
Implementing new technologies poses many technical challenges, for example, performance, scalability, interoperability, security, and resource management. New technologies and solutions typically begin with analytical methods, relying on simulation-based system analysis. Testing and validation are then conducted in the realistic laboratory prior the field tests and real deployment. In-between these two steps, new methods with cost-effectiveness and flexibility are needed to deal with system complexity, consisting of hardware and software rather than purely analytical approach alone. Our smart grid test group aims to bridge the research gaps on how to implement new solutions from initial design (i.e., simulation) to field test (i.e., validation). We adopt a holistic approach to ensure highly and secure automated energy system operations.
Real-time systems: Investigating the interaction between hardware and software components through real-time simulation and emulation, ensuring secure, interoperable, robust, and efficient communication for the seamless integration of all system components and processes.
Co-simulation: Co-simulation offers new opportunities for integrating various simulation components by enabling the coupling of different analytic methods using different interfaces to programming languages and paradigms within a simulation environment.
Flexibility Coordination: Coordination of flexibility requires data exchange and communication between players. Effective aggregation methods enhance resilience of flexibility management and coordination among market players.
Virtualized Services: Leveraging virtualization technologies enable fully automated service selection, configuration, parameterization, and execution for smart substation service management. In addition, engineering concepts based on IEC61850 and orchestration software supports the seamless integration across substations.
Holistic Testing and Validation: Transferring new solutions from initial design (e.g., simulation) to field testing (e.g., validation) through a holistic testing and validation, ensuring comprehensive prototype and successful deployment.
Automation laboratory: The Automation Laboratory provides large-scale real-time simulation and co-simulation with software and hardware coupling, offering realistic environments with industrial components and protocols to analyse system interdependencies, integrate new components, and address real-world challenges.
These five research topics complement each other, leveraging the automation laboratory infrastructure to conduct comprehensive research on pioneering technologies for energy systems and test their applicability in the real world.
