In an era where the demand for reliable and efficient power systems is surging, a groundbreaking study led by Salvatore D’Arco from SINTEF Energy Research in Trondheim, Norway, unveils a sophisticated approach to testing power converters and intelligent electronic devices (IEDs). This research, published in the IEEE Open Journal of Power Electronics, introduces a multi-hardware-in-the-loop (M-HiL) testing framework that could revolutionize how we monitor and control large-scale power systems.
D’Arco’s team has developed a laboratory infrastructure that leverages digital real-time simulation (RTS) platforms, capable of executing both phasor-based simulations and hybrid electromagnetic transient (EMT) simulations. This dual capability is crucial for enhancing the accuracy and reliability of power system testing. “Our approach allows for a more dynamic interaction between real hardware and simulated environments, which is essential for developing advanced grid technologies,” D’Arco explains.
The M-HiL testing environment incorporates high-bandwidth power amplifiers that serve as the interface between real-time simulated power systems and actual hardware. This integration is particularly significant for sectors like renewable energy, where the complexities of systems such as offshore wind farms require meticulous testing to ensure stability and performance. The research highlights how two phasor measurement units (PMUs) work in tandem with a converter configuration that emulates a high-voltage direct current (HVDC) transmission system, providing insights into system behavior under various conditions.
One of the most compelling aspects of this study is the demonstration of a grid forming converter operated as a Virtual Synchronous Machine (VSM). This innovative technology can offer frequency support to the Nordic power system, a critical capability as we transition to more decentralized energy resources. D’Arco emphasizes the importance of this development: “By simulating real-world scenarios, we can ensure that our power systems remain stable and efficient, even as we integrate more renewable sources.”
The implications of this research extend beyond theoretical frameworks; they promise tangible commercial impacts. As energy companies strive to enhance the resilience and efficiency of their operations, the ability to conduct rigorous testing in a controlled environment can lead to faster implementation of new technologies. This is particularly relevant in the context of increasing regulatory pressures and the urgent need for sustainable energy solutions.
The research not only paves the way for improved testing methodologies but also sets the stage for future innovations in grid technology. By refining the tools available for power system monitoring and control, D’Arco and his team are contributing to a more robust energy infrastructure that can adapt to the evolving landscape of energy generation and consumption.
